There are two things achieved by this change:
- No possible downcast of size_t to int when calculating motion steps.
- Disambiguate call to `min()` which was for some reason considered
ambiguous on 32bit platforms `min(int, unsigned int)`.
- Do the same for the `max()` call to keep them symmetrical.
On an implementation side the `min()` is defined for a fixed width
integer type to disambiguate uint from size_t on 32bit platforms,
and yet be able to use it for 32bit operands on 64bit platforms without
upcast.
This ended up in a bit bigger change as the conditional compile-in of
functions is easiest if the functions is templated. Making the functions
templated required to remove the other source of ambiguity which is
`algorithm.h` which was pulling min/max from std.
Now it is the `math.h` which is the source of truth for min/max.
It was only one place which was relying on `algorithm.h` for these
functions, hence the choice of `math.h` as the safest and least
intrusive.
Fixes 32bit platforms (such as i386) in Debian package build system.

This is almost always meaningless as most code has changed
since the comment was added. Besides this, version control can be used
to check if/when a file was modified.
Some cases of this were kept when they contain details
about the original copyright holder.
Order copyright immediately after the license block,
this was done almost everywhere with a few exceptions.
Remove authors from a few files (we had already removed "Contributors"
section however with old patches being applied this gets added back in).
Also move descriptive text into the doxygen comment block under \file.
In some cases remove the text as it was accidentally copied.
GHOST_ISystem::toggleConsole had a somewhat misleading name
it could be fed 4 different values, so it was not as much a
toggle as a set console window state.
This change renames `toggleConsole` to a more appropriately
named `setConsoleWindowState` and replaces the integer it had
to an enum so it's easy to tell what is being asked of it at
the call site.

Based on discussions from T95355 and T94193, the plan is to use
the name "Curves" to describe the data-block container for multiple
curves. Eventually this will replace the existing "Curve" data-block.
However, it will be a while before the curve data-block can be replaced
so in order to distinguish the two curve types in the UI, "Hair Curves"
will be used, but eventually changed back to "Curves".
This patch renames "hair-related" files, functions, types, and variable
names to this convention. A deep rename is preferred to keep code
consistent and to avoid any "hair" terminology from leaking, since the
new data-block is meant for all curve types, not just hair use cases.
The downside of this naming is that the difference between "Curve"
and "Curves" has become important. That was considered during
design discussons and deemed acceptable, especially given the
non-permanent nature of the somewhat common conflict.
Some points of interest:
- All DNA compatibility is lost, just like rBf59767ff9729.
- I renamed `ID_HA` to `ID_CV` so there is no complete mismatch.
- `hair_curves` is used where necessary to distinguish from the
existing "curves" plural.
- I didn't rename any of the cycles/rendering code function names,
since that is also used by the old hair particle system.

If the console was hidden on windows, it would
be made visible during shutdown in an effort
not hide a potentially active interactive console
session. This however did not take in account
if blender was actually launched from an interactive
console causing the console window to briefly flash
during shutdown even when launched from the new
launcher, the brief flash concerned some users.
This change adjusts the behaviour to restore the
console only when blender was started from the
console.

Initialization with `MEM_new()` depends a lot on the initialization rules
of C++, which are not obvious. Calling it with no arguments to be passed
to the constructor may cause the resulting object to be implicitly 0
initialized (or parts of it). This can have an impact on performance
sensitive code, so it's something to document.
Alternatively we could enforce default initialization (as opposed to the
value initalization that happens now), but this could cause
uninitialized memory in a way that isn't obvious either. This is a
possible source of bugs, so Jacques and I decided against it.
This patch refactors the "Hair" data-block, which will soon be renamed
to "Curves". The larger change is switching from an array of `HairCurve`
to find indices in the points array to simply storing an array of offsets.
Using a single integer instead of two halves the amount of memory for that
particular array.
Besides that, there are some other changes in this patch:
- Split the data-structure to a separate `CurveGeometry`
DNA struct so it is usable for grease pencil too.
- Update naming to be more aligned with newer code and the style guide.
- Add direct access to some arrays in RNA
-- Radius is now retrieved as a regular attribute in Cycles.
-- `HairPoint` has been renamed to `CurvePoint`
-- `HairCurve` has been renamed to `CurveSlice`
- Add comments to the struct in DNA.
The next steps are renaming `Hair` -> `Curves`, and adding support
for other curve types: Bezier, Poly, and NURBS.

Previously, macros were ifdefed using the cmake option `WITH_INTERNATIONAL`
However, the is unnecessary as withen the functions themselves have checks for building without internationalization.
This also means that many `add_definitions(-DWITH_INTERNATIONAL)` are also unnecessary.

Sometime throughout development some checks got lost during refactor.
This change makes it so that if OIDN is not supported on the current
CPU Cycles will report an error and stop rendering. This behavior is
similar to when an OptiX denoiser is requested and there is no OptiX
compatible device available.
The easiest way to verify this change is to force return false from
the `openimagedenoise_supported()`.

Remove small ray offsets that were used to avoid self intersection, and leave
that to the newly added primitive object/prim comparison. These changes together
significantly reduce artifacts on small, large or far away objects.
The balance here is that overlapping primitives are not handled well and should
be avoided (though this was already an issue). The upside is that this is
something a user has control over, whereas the other artifacts had no good
manual solution in many cases.
There is a known issue where the Blender particle system generates overlapping
objects and in turn leads to render differences between CPU and GPU. This will
be addressed separately.

The OSL image compilation step needed to be taught about the new UVTILE

A small missing feature from OIIO[1] means this is a bit uglier than it
needs to be. Once we update to a version of OIIO with the fix we can
remove the string replace part.
