Not all matrices are invertable (e.g. when a transformation matrix is has
a scale of zero), and it's sometimes important when a matrix is.
This also better specifies the behavior when the matrix is not invertable:
the identity matrix is returned.

For various reasons, the animation system can't properly update the node tree
so that the socket availability caused by changing node enum properties
propagates completely. So animating node properties that affect
socket visibility to change isn't possible without issues like crashes.
Unfortunately that wasn't disallowed before. In this commit there is
a balance of disabling animation on sockets that could reasonably expected
to affect socket visibility, and minimizing breaking changes.

This fixes the following name collisions:
* Compositor Box/Ellipse Mask node: `width` -> `mask_width`
(also renamed the `height` property accordingly)
* Shader AOV Output node: `name` -> `aov_name`
* Geometry Color node: `color` -> `value`.
Those are breaking changes unfortunately, because looking up those property
names yielded the node-specific and not the common property. Therefore, this is
targeted at `main` instead of `4.1`.

`sock_rotation` has higher priority (6) than the vector socket (4).
Hence inserting node between vector-vector link joins thorugh "rotation"
socket (`get_main_socket()` / `get_main_socket_priority()`).
This can be fixed by making "vector" input socket as default for link.
But this will break the link creation when node is inserted between
rotation-rotation link. It seems rotation is converted to vectors so
perhaps make sense to make "vector" as default socket for link.

Implements the design from #116067.
The socket type is called "Matrix" but it is often referred to as "Transform"
when that's what it is semantically. The attribute type is "4x4 Matrix" since
that's a lower level choice. Currently matrix sockets are always passed
around internally as `float4x4`, but that can be optimized in the future
when smaller types would give the same behavior.
A new "Matrix" utilities category has the following set of initial nodes"
- **Combine Transform**
- **Separate Transform**
- **Multiply Matrices**
- **Transform Direction**
- **Transform Vector**
- **Invert Matrix**
- **Transpose Matrix**
The nodes and socket type are behind an experimental flag for now,
which will give us time to make sure it's the right set of initial nodes.
The viewer node overlay doesn't support matrices-- they aren't supported
for rendering in general. They also aren't supported in the modifier interface
currently. But they are supported in the spreadsheet, where the value is
displayed in a tooltip.

In 4.1 we deprecate the `Rotate Euler` node in favor of the `Rotate Rotation`
node which uses the new rotation socket type. The node is not removed
(for now) because that would come with compatibility issues. More generally,
we'll likely run into the situation where nodes are deprecated more often in the
future, without actually removing them to keep compatibility. This patch improves
how such nodes are handled in the UI.
The patch does three things:
* Adds a new `Utilities > Deprecated` entry in the add node menu in geometry nodes.
* Moves search items which are deprecated to the bottom in the search results
(currently, this only works in English, can be fixed in bcon3).
* Adds a new `bNodeType->deprecation_notice` that will result in a deprecation
warning when the node is used.

All the option does internally is reverse the order of the rotations,
but this is the same as old "Rotate Euler" node, and it's a bit more
intuitive this way. Also use the same socket names, "Rotation" and
"Rotate By" which are much more intuitive.
Technically it would be better to not have to duplicate the multi-
function just to switch the order of the arguments. But the
evaluator assumes that the order always matches the socket
order currently.

This is meant as a replacement for the Rotate Euler node. Overall it
should be more performant, and the clarity given by the separate socket
type should help distinguish its purpose.
The Rotate Euler node is removed from search and the add menu by this
commit. In the future it can be versioned away. That isn't done now to
avoid a breaking API change and to make this commit less risky.

The previous commit introduced a new `RPT_()` macro to translate
strings which are not tooltips or regular interface elements, but
longer reports or statuses.
This commit uses the new macro to translate many strings all over the
UI.
Most of it is a simple replace from `TIP_()` or `IFACE_()` to
`RPT_()`, but there are some additional changes:
- A few translations inside `BKE_report()` are removed altogether
because they are already handled by the translation system.
- Messages inside `UI_but_disable()` are no longer translated
manually, but they are handled by a new regex in the translation
system.

Due to changes in the build environment shader_builder wasn't able to
compile on macOs. This patch reverts several recent changes to CMake files.
* dbb2844ed9
* 94817f64b9
* 1b6cd937ff
The idea is that in the near future shader_builder will run on the buildbot as
part of any regular build to ensure that changes to the CMake doesn't break
shader_builder and we only detect it after a few days.

This helps solving the problem encountered in #113553. The problem is that we
currently can't support link-drag-search for nodes which have a dynamic declaration.
With this patch, there is only a single `declare` function per node type, instead of
the separate `declare` and `declare_dynamic` functions. The new `declare` function
has access to the node and tree. However, both are allowed to be null. The final
node declaration has a flag for whether it depends on the node context or not.
Nodes that previously had a dynamic declaration should now create as much of
the declaration as possible that does not depend on the node. This allows code
like for link-drag-search to take those sockets into account even if the other
sockets are dynamic.
For node declarations that have dynamic types (e.g. Switch node), we can also
add extra information to the static node declaration, like the identifier of the socket
with the dynamic type. This is not part of this patch though.
I can think of two main alternatives to the approach implemented here:
* Define two separate functions for dynamic nodes. One that creates the "static
declaration" without node context, and on that creates the actual declaration with
node context.
* Have a single declare function that generates "build instructions" for the actual
node declaration. So instead of building the final declaration directly, one can for
example add a socket whose type depends on a specific rna path in the node.
The actual node declaration is then automatically generated based on the build
instructions. This becomes quite a bit more tricky with dynamic amounts of sockets
and introduces another indirection between declarations and what sockets the node
actually has.
I found the approach implemented in this patch to lead to the least amount of
boilerplate (doesn't require a seperate "build instructions" data structure) and code
duplication (socket properties are still only defined in one place). At the same time,
it offers more flexibility to how nodes can be dynamic.
Pull Request: https://projects.blender.org/blender/blender/pulls/113742
Strings that include Latin1 encoding or corrupt UTF8 byte sequences
could read past the buffer bounds (stepping over the null terminator).
Resolve by passing in the string length.
Other changes to support non-UTF8 byte sequences:
- BLI_str_utf8_offset_{to/from}_index were accumulating
the UTF8 offset without accounting for non-UTF8 characters
which could cause a buffer underflow or enter an eternal loop.
- BLI_str_utf8_offset_to_index would read past the buffer bounds if the
offset passed in if it was in the middle of a UTF8 byte sequence.
Now that specific menus can be searched directly (see 7f9d51853c),
there is no need to maintain separate search functionality for adding
nodes. This PR removes the add node search. In a way this brings us
closer to the `NodeItem` situation before, but the setup is more
flexible since the menus are more standard and easier to customize.
In the few ways we customized the node search items before, this gives
us the same results as before. Overall the searching is less flexible,
but I think that is just a tradeoff we have to accept for the simplicity
of searching menus. In the future menus could be made more dynamic,
with each builtin node's menu path stored on the node type, similar to
assets. That might be a nice compromise. In the meantime this code
is just dead weight.

This was noted in code comments and checked in Python documentation
generation but not at build time.
Since these enums are identifiers that end up included in various places
enforce the `rna_enum_*_items` convention which was noted as
the convention but not followed strictly.
Partially reverts [0], avoids having to deal with multiple prefix types.

This PR adds an initial set of nodes using the new rotation socket.
6 nodes build rotations or convert them to other formats, a 7th rotates
a vector with a rotation, and the last inverts rotations.
The design task #109965 describes the choice to use separate nodes
for the rotation construction and separation operations. In the future,
a "Switch Node" operator (#111438) will help to make working with
these separated nodes faster.
- **Axis Angle to Rotation**
- **Rotation to Axis Angle**
- **Combine Quaternion**
- **Separate Quaternion**
- **Euler to Rotation**
- **Rotation to Euler**
- **Rotate Vector**
- **Invert Rotation**

This commit allows both `rna_enum_` and `rna_node_`to be used for enum prefixes
This also fixes one enum by adding `rna_` to the prefix.
Together these changes fix the API documentation generation.
Including <iostream> or similar headers is quite expensive, since it
also pulls in things like <locale> and so on. In many BLI headers,
iostreams are only used to implement some sort of "debug print",
or an operator<< for ostream.
Change some of the commonly used places to instead include <iosfwd>,
which is the standard way of forward-declaring iostreams related
classes, and move the actual debug-print / operator<< implementations
into .cc files.
This is not done for templated classes though (it would be possible
to provide explicit operator<< instantiations somewhere in the
source file, but that would lead to hard-to-figure-out linker error
whenever someone would add a different template type). There, where
possible, I changed from full <iostream> include to only the needed
<ostream> part.
For Span<T>, I just removed print_as_lines since it's not used by
anything. It could be moved into a .cc file using a similar approach
as above if needed.
Doing full blender build changes include counts this way:
- <iostream> 1986 -> 978
- <sstream> 2880 -> 925
It does not affect the total build time much though, mostly because
towards the end of it there's just several CPU cores finishing
compiling OpenVDB related source files.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
Using ClangBuildAnalyzer on the whole Blender build, it was pointing
out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file
that is included a lot).
However, there's very little (actually zero) source files in Blender
that need "all the math" (base, colors, vectors, matrices,
quaternions, intersection, interpolation, statistics, solvers and
time). A common use case is source files needing just vectors, or
just vectors & matrices, or just colors etc. Actually, 181 files
were including the whole math thing without needing it at all.
This change removes BLI_math.h completely, and instead in all the
places that need it, includes BLI_math_vector.h or BLI_math_color.h
and so on.
Change from that:
- BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec
to parse -> now 36.3sec)
- BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec).
Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not
affected much (342sec -> 334sec). Most of benefit would be when
someone's changing BLI_simd.h or BLI_math_color.h or similar files,
that now there's 3x fewer files result in a recompile.
Pull Request #110944
The goal here is to reduce the number of files that need to be edited when
adding a new node. To register a node, one currently has to add a line to
`node_geometry_register.cc` and `node_geometry_register.hh` (for geometry
nodes). Those files can be generated automatically.
There is a new `NOD_REGISTER_NODE` macro that nodes can use to register
themselves. The macro is then discovered by `discover_nodes.py` that generates
code that calls all the registration functions. The script also works when the
register functions are in arbitrary namespaces. This allows simplifying the node
code as well.
In the past I tried a few times to get auto-registration working without resorting to
code generation, but that never ended up working. The general idea for that would
be to use non-trivial initialization for static variables. The issue always ends up
being that the linker just discards those variables, because they are unused and it
doesn't care if there are side effects in the initialization.

The cleanup of blenkernel last weeks , caused the house of cards to
collapse on top of bf_gpu's shader_builder, which is off by default
but used on a daily basis by the rendering team.
Given the fixes forward in #110394 ran into a ODR violation in OSL that
was hiding there for years, I don't see another way forward without
impeding the rendering teams productivity for "quite a while" as there
is no guarantee the OSL issue would be the end of it.
the only way forward appears to be back.

The problematic commit was 07fe6c5a57
as blenkernel links most of blender, it's a bit of a link order issue
magnet. Given all these commits stack, it's near impossible to revert
just that one without spending a significant amount of time resolving
merge conflicts. 99% of that work was automated, so easier to just
revert all of them, and re-do the work, than it is to deal with the
merge conflicts.

There's quite a few libraries that depend on dna_type_offsets.h
but had gotten to it by just adding the folder that contains it to
their includes INC section without declaring a dependency to
bf_dna in the LIB section.
which occasionally lead to the lib building before bf_dna and the
header being missing, while this generally gets fixed in CMake by
adding bf_dna to the LIB section of the lib, however until last
week all libraries in the LIB section were linked as INTERFACE so
adding it in there did not resolve the build issue.
To make things still build, we sprinkled add_dependencies wherever
we needed it to force a build order.
This diff :
Declares public include folders for the bf_dna target so there's
no more fudging the INC section required to get to them.
Removes all dna related paths from the INC section for all
libraries.
Adds an alias target bf:dna to signify it has been updated to
modern cmake
Declares a dependency on bf::dna for all libraries that require it
Removes (almost) all calls to add_dependencies for bf_dna
Future work:
Because of the manual dependency management that was done, there is
now some "clutter" with libs depending on bf_dna that realistically
don't. Example bf_intern_opencolorio itself has no dependency on
bf_dna at all, doesn't need it, doesn't use it. However the
dna include folder had been added to it in the past since bf_blenlib
uses dna headers in some of its public headers and
bf_intern_opencolorio does use those blenlib headers.
Given bf_blenlib now correctly declares the dependency on bf_dna
as public bf_intern_opencolorio will get the dna header directory
automatically from CMake, hence some cleanup could be done for
bf_intern_opencolorio
Because 99% of the changes in this diff have been automated, this diff
does not seek to address these issues as there is no easy way to
determine why a certain dependency is in place. A developer will have
to make a pass a this at some later point in time. As I'd rather not
mix automated and manual labour.
There are a few libraries that could not be automatically processed
(ie bf_blendthumb) that also will need this manual look-over.

String search & replace is a higher level function (unlike BLI_string.h)
which handlers lower level replacements for printing and string copying.
Also use BLI_string_* prefix (matching other utilities).
This makes it possible to use BLI_string in Blender's internal utilities
without depending on DynStr, MemArena... etc.
