In some situations the zero axis can produce problems and need to add a small bias.
This function adds a small bias using the orthogonal result of the others valid axis.

Although rB67e23b4b2967 turned the problem more recurrent, the warning
messages in the console always appear when `BKE_fluid_cache_free_all`
is called.
This is because of a bug in `BLI_filelist_dir_contents` as this function
calls `BLI_strdupcat` instead of `BLI_join_dirfile`
NOTE: Other places in Blender avoid this problem by making sure to add
a `SEP_STR` to the end of the directory.

Match minimum supported versions from the WIKI [0] by raising them to:
- GCC 9.3.1
- CLANG 8.0
- MVCS 2019 (16.9.16 / 1928)
Details:
- Add CMake checks that ensure supported compiler versions early on.
- Previously GCC per-processor version checks served to exclude
`__clang__`, in some cases this has been replaced by explicitly
excluding `__clang__`. This was needed as CLANG treated some of these
flags differently to GCC, causing the build to fail.
- Remove USE_APPLE_OMP_FIX GCC-4.2 OpenMP workaround.
- Remove linking error workaround for old MSVC versions.

In large node setup the threading overhead was sometimes very significant.
That's especially true when most nodes do very little work.
This commit improves the scheduling by not using multi-threading in many
cases unless it's likely that it will be worth it. For more details see the comments
in `BLI_lazy_threading.hh`.

Add new functions to `array_utils` namespace called `gather(..)`.
Versions of `GVArray::materialize_compressed_to_uninitialized(..)` with
threading have been reimplemented locally in multiple geometry node
contexts. The purpose of this patch is therefore to:
* Assemble these implementations in a single file.
* Provide a naming convention that is easier to recognize.

The trim functionality is implemented in the geometry module, and
generalized a bit to be potentially useful for bisecting in the future.
The implementation is based on a helper type called `IndexRangeCyclic`
which allows iteration over all control points between two points on a
curve.
Catmull Rom curves are now supported-- trimmed without resampling first.
However, maintaining the exact shape is not possible. NURBS splines are
still converted to polylines using the evaluated curve concept.
Performance is equivalent or faster then a 3.1 build with regards to
node timings. Compared to 3.3 and 3.2, it's easy to observe test cases
where the node is at least 3 or 4 times faster.

This refactors the geometry nodes evaluation system. No changes for the
user are expected. At a high level the goals are:
* Support using geometry nodes outside of the geometry nodes modifier.
* Support using the evaluator infrastructure for other purposes like field evaluation.
* Support more nodes, especially when many of them are disabled behind switch nodes.
* Support doing preprocessing on node groups.
For more details see T98492.
There are fairly detailed comments in the code, but here is a high level overview
for how it works now:
* There is a new "lazy-function" system. It is similar in spirit to the multi-function
system but with different goals. Instead of optimizing throughput for highly
parallelizable work, this system is designed to compute only the data that is actually
necessary. What data is necessary can be determined dynamically during evaluation.
Many lazy-functions can be composed in a graph to form a new lazy-function, which can
again be used in a graph etc.
* Each geometry node group is converted into a lazy-function graph prior to evaluation.
To evaluate geometry nodes, one then just has to evaluate that graph. Node groups are
no longer inlined into their parents.
Next steps for the evaluation system is to reduce the use of threads in some situations
to avoid overhead. Many small node groups don't benefit from multi-threading at all.
This is much easier to do now because not everything has to be inlined in one huge
node tree anymore.

This function did multiple things making it difficult to know
what was intended by the caller:
- Directory & file join.
- Expand relative '//' prefix to an optional directory.
- Expand drive letters on windows (guessing with fall-backs).
- Switch slashes to native direction.
This functionality wasn't needed as the full directory was always passed
in, so guessing the drive letter wasn't needed.
If functionality to add drive letters onto paths is needed in the future
a function that only does this can be added.
This patch implements the pixelate node for the realtime compositor.

This adds a new `blender::BitVector` data structure that was requested
a couple of times. It also replaces usages of `BLI_bitmap` in C++ code.
See the comment in `BLI_bit_vector.hh` for more details about the
advantages and disadvantages of using a bit-vector and how the new
data structure compares to `std::vector<bool>` and `BLI_bitmap`.

When allocating new `CustomData` layers, often we do redundant
initialization of arrays. For example, it's common that values are
allocated, set to their default value, and then set to some other
value. This is wasteful, and it negates the benefits of optimizations
to the allocator like D15082. There are two reasons for this. The
first is array-of-structs storage that makes it annoying to initialize
values manually, and the second is confusing options in the Custom Data
API. This patch addresses the latter.
The `CustomData` "alloc type" options are rearranged. Now, besides
the options that use existing layers, there are two remaining:
* `CD_SET_DEFAULT` sets the default value.
* Usually zeroes, but for colors this is white (how it was before).
* Should be used when you add the layer but don't set all values.
* `CD_CONSTRUCT` refers to the "default construct" C++ term.
* Only necessary or defined for non-trivial types like vertex groups.
* Doesn't do anything for trivial types like `int` or `float3`.
* Should be used every other time, when all values will be set.
The attribute API's `AttributeInit` types are updated as well.
To update code, replace `CD_CALLOC` with `CD_SET_DEFAULT` and
`CD_DEFAULT` with `CD_CONSTRUCT`. This doesn't cause any functional
changes yet. Follow-up commits will change to avoid initializing
new layers where the correctness is clear.

The calculation was revised to address two issues:
* Discontinuities occurring when detail was a non-integer greater than 2.
* Levels of detail in the interval [0,1) repeating the levels of detail in
the interval [1,2).
This fixes Cycles, Eevee and geometry nodes.

Making the callers responsible for this isn't practical as matrices are
often passed indirectly to a functions such as mat3_to_axis_angle,
BKE_object_mat3_to_rot & BKE_pchan_mat3_to_rot.
Or the matrix is combined from other matrices which could be negative.
Given quaternions calculated from negative matrices are completely
invalid and checking only needs to negate matrices with a negative
determinant, move the check into mat3_to_quat and related functions.
Add mat3_normalized_to_quat_fast for cases no error checking on the
input matrix is needed such as blending rotations.
Use a more direct method of checking if a matrix is negative instead of
using cross & dot product.
Also replace some determinant_m3() < 0 checks with is_negative_m3.
Instead of using macros like GLIBC we can use the CMake build
systems internal functions to check if some header or functions are
present on the running system's libc.
Add ./build_files/cmake/have_features.cmake to add checks for
platform features which can be used to set defines for source
files that require them.
