Those collections were so far mainly just tagged as fake user (even
though a few places in code already incremented usercount on them).
Since we now clear the fakeuser flag when linking/appending data, ensure
that these collections are preserved by making these usages regular ID
refcounting ones.

With libepoxy we can choose between EGL and GLX at runtime, as well as
dynamically open EGL and GLX libraries without linking to them.
This will make it possible to build with Wayland, EGL, GLVND support while
still running on systems that only have X11, GLX and libGL. It also paves
the way for headless rendering through EGL.
libepoxy is a new library dependency, and is included in the precompiled
libraries. GLEW is no longer a dependency, and WITH_SYSTEM_GLEW was removed.

The specific functions for vertex colors and and sculpt vertex colors
can be replaced by more generic attribute functions internally.
Also remove a paramter from one function.
It's helpful to make the separation of legacy data formats explicit,
because it declutters actively changed code and makes it clear which
areas do not follow Blender's current design. In this case I separated
the `MFace`/"tessface" conversion code into a separate blenkernel
.cc file and header. This also makes refactoring to remove these
functions simpler because they're easier to find.
In the future, conversions to the `MLoopUV` type and `MVert`
can be implemented here for the same reasons (see T95965).

Removes the following macros for scene/render frame values:
- `CFRA`
- `SUBFRA`
- `SFRA`
- `EFRA`
These macros don't add much, other than saving a few characters when typing.
It's not immediately clear what they refer to, they just hide what they
actually access. Just be explicit and clear about that.
Plus these macros gave read and write access to the variables, so eyesores like
this would be done (eyesore because it looks like assigning to a constant):

As described in T91186, this commit moves mesh vertex normals into a
contiguous array of float vectors in a custom data layer, how face
normals are currently stored.
The main interface is documented in `BKE_mesh.h`. Vertex and face
normals are now calculated on-demand and cached, retrieved with an
"ensure" function. Since the logical state of a mesh is now "has
normals when necessary", they can be retrieved from a `const` mesh.
The goal is to use on-demand calculation for all derived data, but
leave room for eager calculation for performance purposes (modifier
evaluation is threaded, but viewport data generation is not).
**Benefits**
This moves us closer to a SoA approach rather than the current AoS
paradigm. Accessing a contiguous `float3` is much more efficient than
retrieving data from a larger struct. The memory requirements for
accessing only normals or vertex locations are smaller, and at the
cost of more memory usage for just normals, they now don't have to
be converted between float and short, which also simplifies code
In the future, the remaining items can be removed from `MVert`,
leaving only `float3`, which has similar benefits (see T93602).
Removing the combination of derived and original data makes it
conceptually simpler to only calculate normals when necessary.
This is especially important now that we have more opportunities
for temporary meshes in geometry nodes.
**Performance**
In addition to the theoretical future performance improvements by
making `MVert == float3`, I've done some basic performance testing
on this patch directly. The data is fairly rough, but it gives an idea
about where things stand generally.
- Mesh line primitive 4m Verts: 1.16x faster (36 -> 31 ms),
showing that accessing just `MVert` is now more efficient.
- Spring Splash Screen: 1.03-1.06 -> 1.06-1.11 FPS, a very slight
change that at least shows there is no regression.
- Sprite Fright Snail Smoosh: 3.30-3.40 -> 3.42-3.50 FPS, a small
but observable speedup.
- Set Position Node with Scaled Normal: 1.36x faster (53 -> 39 ms),
shows that using normals in geometry nodes is faster.
- Normal Calculation 1.6m Vert Cube: 1.19x faster (25 -> 21 ms),
shows that calculating normals is slightly faster now.
- File Size of 1.6m Vert Cube: 1.03x smaller (214.7 -> 208.4 MB),
Normals are not saved in files, which can help with large meshes.
As for memory usage, it may be slightly more in some cases, but
I didn't observe any difference in the production files I tested.
**Tests**
Some modifiers and cycles test results need to be updated with this
commit, for two reasons:
- The subdivision surface modifier is not responsible for calculating
normals anymore. In master, the modifier creates different normals
than the result of the `Mesh` normal calculation, so this is a bug
fix.
- There are small differences in the results of some modifiers that
use normals because they are not converted to and from `short`
anymore.
**Future improvements**
- Remove `ModifierTypeInfo::dependsOnNormals`. Code in each modifier
already retrieves normals if they are needed anyway.
- Copy normals as part of a better CoW system for attributes.
- Make more areas use lazy instead of eager normal calculation.
- Remove `BKE_mesh_normals_tag_dirty` in more places since that is
now the default state of a new mesh.
- Possibly apply a similar change to derived face corner normals.

After disconnecting hair on an object, if you then hide the particle system, and try connecting the hair again, the operator is cancelled due to `remap_hair_emitter` returning `false` because `target_psmd->mesh_final` is NULL, but `connect_hair` will still strip the `PSYS_GLOBAL_HAIR` flag, which will cause the hair in the hidden particle system to be positioned incorrectly. The correct behavior is to strip the flag only if `remap_hair_emitter` succeeds.

Fixes a bug introduced in rB5dedb39d447b. `mesh_original` is not set if the

Before this patch attempting to remove a particle modifier programmatically
through Python would fail, because it deleted the modifier associated with
the currently active particle system instead of the one passed as an argument
to `bpy.types.ObjectModifiers.remove()`.
This fix adds an additional argument for the particle system to
`object_remove_particle_system`. This allows to specify which particle system
and its associated modifier shall be removed. In case of
`particle_system_remove_exec` it will remain the currently active particle
system, whereas `object_remove_particle_system` passes the particle system
of the modifier. Hence, the correct modifier will be removed.

The depth cache (located in `RegionView3D::depths`) is used for quick
and simple occlusion testing in:
- particle selection,
- "Draw Curve" operator and
- "Interactive Light Track to Cursor" operator,
However, keeping a texture buffer in cache is not a recommended practice.
For displays with high resolution like 8k this represents something
around 132MB.
Also, currently, each call to `ED_view3d_depth_override` invalidates
the depth cache. So that depth is never reused in multiple calls from
an operator (this was not the case in blender 2.79).
This commit allows to create a depth cache and release it in the same
operator. Thus, the buffer is kept in cache for a short time, freeing
up space.
