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.

Since VBO stands for vertex buffer object it should always be uppercase.
"Vertex" in "vertex buffer object" should only be capitalized at the
beginning of a sentence.

Some performance issues were found here with a heavy production file and
we want to look into using some C++ to improve things for this ancient
code.

Comments there weren't really helpful, took me a while to get what they
try to say. This attempts to add a better explanation. Also add an
assert for a previous, implicit (but commented) assumption, and some
minor cleanups.

Was always creating a copy of `SpaceOutliner`, even though it's only
needed for one conditional branch. This is a shallow copy, so shouldn't
be that expensive, still trivial to avoid.

The iterator parameters struct should be initialized to zero in both
C and C++. Using memset seems to be the only reliable way to do that.

Metaball, curve, text, and surface objects use the geometry component
system to add evaluated mesh object instances to the dependency graph
"for render engine" iterator. Therefore it is unnecessary to process
those object types in these loops-- it would either be redundant work
or a no-op.

This behavior is now implicitely controlled by the 'Make' operations,
based either on context or selected items.

Also remove two DispList references I missed in the previous commit.

The object data path item wasn't added properly.
Also remove some of the unnecessary variables and forward declarations.

With the ultimate goal of simplifying drawing and evaluation,
this patch makes the following changes and removes code:
- Use `Mesh` instead of `DispList` for evaluated basis metaballs.
- Remove all `DispList` drawing code, which is now unused.
- Simplify code that converts evaluated metaballs to meshes.
- Store the evaluated mesh in the evaluated geometry set.
This has the following indirect benefits:
- Evaluated meshes from metaball objects can be used in geometry nodes.
- Renderers can ignore evaluated metaball objects completely
- Cycles rendering no longer has to convert to mesh from `DispList`.
- We get closer to removing `DispList` completely.
- Optimizations to mesh rendering will also apply to metaball objects.
The vertex normals on the evaluated mesh are technically invalid;
the regular calculation wouldn't reproduce them. Metaball objects
don't support modifiers though, so it shouldn't be a problem.
Eventually we can support per-vertex custom normals (T93551).

This is old code to keep track of an active search element, so you could
step through the search results. This isn't used anymore, and not needed
since searching now filters the tree to only show matches. If we ever
wanted to have support for stepping through elements again, that should be
done via the active element instead.

Almost entirely adding casting and standard clang tidy changes.
Also switch to `blender::Vector` instead of the macro-based `BLI_array`.

The movie clip GPU texture free function doesn't do null checks, so make

handle_subversion_warning() was reporting with RPT_ERROR type, replaced
with RPT_WARNING.
RPT_ERROR would stop python scripts opening files written by newer
Blender binary with bpy.ops.wm.open_mainfile(), preventing further code
from running. This does not seem right since Blender itself still loads
the files.
Ran into this checking T100446 in 2.93.

Pressing escape when rendering a viewport animation would
access the freed even and crash (with ASAN enabled).
Always check the context's window before the event as this is a signal
a file was loaded or the window was closed (and it's events freed).

Use an off-screen buffer for the screen-shot operator.
Reading from the front-buffer immediately after calling swap-buffers
failed for GHOST/Wayland in some cases.
While EGL can request to preserve the front-buffer while drawing,
this isn't always supported. So workaround the problem by avoiding
use of the front-buffer entirely.

These macros don't compile in C++ because of taking an address of a
temporary and use of designated initializers. Besides that, using
functions can improve debugging and type safety.

Implementation of the FreeType 2 cache subsystem, which limits the
number of concurrently-opened FT_Face and FT_Size objects, as well as
caching information like character maps to speed up glyph id lookups.
This time with the option of opening FontBLFs that are not cached.

Commit rBc0845abd897f to 3.4 (master) uses font's filepath without
