- Reduce variable scope.
- Use snake-case for variables.
- Remove unnecessary counter when building file-list.
- Remove break after return.
- Use early return.
- Add missing braces.
- Use pascel-case type names, instead of snake-case with `_t` suffix.
- Use `GWL_` prefix (short for GhostWayLand), to distinguish these
types from ghost (`GHOST_*`) and wayland (`wl_*`) types.
- Rename `input` to `seat` (following wayland's own terminology).
- Use `wl_` prefix for wayland native variables which have locally
defined equivalents so `GWL_Output *output` isn't confused with
`struct wl_output *wl_output`. As the locally defined types are used
more often this is less verbose overall.
Enables a feature flag during OpenGL device initialisation on macOS, which increases the available number of texture samplers available for use within shaders. Enabling this flag removes purple rendering artifacts present in certain EEVEE materials, when the existing limit of 16 is exceeded.
This feature flag is supported on Apple Silicon and AMD GPUs, for devices supporting macOS 11.0+. Device initialisation first tests whether GL device creation with the flag is supported, if not, we fall back to standard initialisation.
Other solutions would not be trivial or incur additional performance overhead or feature limitations. Other workarounds, such as texture atlas's, could already be created by artists.

When 'm_render_target' was NULL, backbuffer_res would be used without
being assigned. While it seems likely this code-path is rarely used
(if at all), resolve the logical error.
Introduced in [0], checking the logic here, there seems to be no reason
a press event should ever run release logic, relocate break statement.
In practice this was unlikely to cause problems as peeking into press
events would need to fail, peeking into release would need to succeed.
Even so, better avoid accidental fall through in switch statements.

Same as other build options, don't make it a hard requirement to have
Wayland libraries installed when it gets enabled by default.
Also fixes wayland-protocols not being found on the buildbot.
Regression in recent fix for T66088 [0]. caused by much older problem
introduced with [1] & [2].
Unlike other platforms, as of [1] GHOST/Win32 was keeping track of the
pressed modifier keys.
Since GHOST/Win32 cleared the modifier state on window activation [2]
and only changes to modifier state would generate key events, activating
the window and releasing the modifier would not send the release event.
Resolve this by removing the stored modifier state from GHOST/Win32,
always passing modifier press/release events through to Blender
(matching other GHOST back-ends).
Instead, use key-repeat detection to prevent repeated modifier keys
from being generated - an alternate solution to T26446.

As mentioned in T89399, "the source of this bug is that cursor wrap
moves the cursor, but when it later checks the mouse position it hasn't
yet been updated, so it re-wraps".
As far as I could see, this happens for two reasons:
1. During the first warp, there are already other mousemove events in the queue with an outdated position.
2. Sometimes Windows occasionally and inexplicably ignores `SetCursorPos()` or `SendInput()` events. (See [1])
The solution consists in checking if the cursor is inside the bounds right after wrapping.
If it's not inside, it indicates that the wrapping either didn't work or the event is out of date.
In these cases do not change the "accum" values.

With this patch true headless OpenGL rendering is now possible on Linux.
It changes the logic of the WITH_HEADLESS build flag.
The headless backend is now always available with regular builds and
Blender will try to fall back to it if it fails to initialize other
backends while in background mode.
The headless backend only works on Linux as EGL is not used on Mac or Windows.
libepoxy does support windows and mac, so this can perhaps be remedied in the future.

This cleans up the OpenGL build flags and linking.
It additionally also removes some dead code.
One of these dead code paths is WITH_X11_ALPHA which actually never was
active even with the build flag on. The call to use this was never
called because the default initializer for GHOST was set to have it off
per default. Nothing called this function with a boolean value to enable it.
These cleanups are needed to support true headless OpenGL rendering.
Without these cleanups libepoxy will fail to load the correct OpenGL
Libraries as we have already linked them to the blender binary.

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.

and Sergey Sharybin.

Take advantage of Waylands wl_keyboard_listener.enter callback which
takes an array of keys that are pressed when a window is activated.
Resolves T74684 under Wayland.
Paths that contained characters that needed escaping as URL's failed
to import.
Move URL decoding to a new file (GHOST_PathUtils), shared with X11 but
maybe be useful for other platforms too.
Drag & drop worked with GTK3 apps but not QT5 (pcmanfm-qt for eg)
as files are separated by '\n' instead of '\r\n'.
Resolve by supporting both (follow up to T99737).
