Cleanup: moved drivers to BKE_fcurve_driver.h / fcurve_driver.c

All the driver-specific code in `fcurve.c` has been moved into a new file
`fcurve_driver.c`. The corresponding declarations have been moved from
`BKE_fcurve.h` to `BKE_fcurve_driver.h`.

All the `#include "BKE_fcurve.h"` statements have been investigated and
replaced with `BKE_fcurve_driver.h` where necessary.

No functional changes.

Fix: added missing buildinfo to BKE_fcurve test

CMake: add WITH_GHOST_X11 option

- Support building only with Wayland.
- In this case, show useful error messages
when Wayland fails to load.

Tests: Animation, added unittests for FCurve evaluation

This introduces unittests for FCurve evaluation.

No functional changes to actual Blender code.

Merge branch 'blender-v2.83-release'

Cleanup: Solidify modifier: Remove unneccessary error message.

For any modifier, the expected output when the input mesh is empty, is an
empty mesh. So this error message was useless, and could spam the
console in some usecases of the modifier stack...

Cleanup: duplicate include, define from Wayland patch

Cleanup: rename WITH_X11 to WITH_GHOST_X11

Matches WITH_GHOST_{SDL|WAYLAND}

GHOST: set the window state on wayland startup

WM: remove X11 hard coded window size workaround

Causes issues with Wayland and is no longer required for Gnome/KDE.

Merge branch 'master' into greasepencil-object

Cleanup: replace inline dot-product with dot_v4v4

Cleanup: improve readability for color assignment

Cleanup: pass const arguments to texture functions

Cleanup: avoid returning a bit-flag as a float

Texture functions were returning a float which was cast back to an int
to use as a flag.

Cleanup: rename externtex to RE_texture_evaluate

- Pass in return arguments last.
- Pass in RGBA as a vector.
- Use boolean return argument.

Cleanup: use sections for outliner sources

Cleanup: spelling, comments

Cleanup: warnings
