This will allow eliminating indirections and making the Xwayland Present
code more efficient and easier to follow.
While this technically changes the Xorg video driver ABI, I don't know
of any drivers using the dropped present_wnmd_* symbols, and I doubt a
Xorg driver could make use of them as is anyway.
(As a bonus, Xorg no longer links any Xwayland specific Present code)
v2:
* Wrap DestroyWindow before initializing Present, so that
present_destroy_window runs before xwl_present_cleanup. Avoids crash
due to present_destroy_window calling xwl_present_* functions when
xwl_present_window was already freed. (Olivier Fourdan)

v2:
* Rename wait_msc → exec_msc (Roman Gilg)
* Use exec_msc = target_msc instead of exec_msc++, for clarity.
* Bug fix: Set exec_msc = target_msc also if present_flip returned
false in present_execute.
v3:
* Set exec_msc = target_msc also if present_wnmd_flip returned
false in present_wnmd_execute, for consistency.

In present_wnmd.c we can simply remove the function which does an unnecessary

In contrast to screen flip mode this mode:
* supports flips per windows (these windows currently need to have the same
size as their parent windows with the same pixmap),
* sends pixmap idle signals to the client only after the driver has given
an additional event notify.
This patch only introduces the new mode as a stub. It additionally needs a
driver hook, such that it can get initialized and appropriate cleanup
functions.

The MSC offset used by a window is adjusted as the window moves
between screens, and between shown/unshown. The value shouldn't
matter, but it's helpful for debugging to have window MSC values be
the same as the CRTC MSC at first.
This patch introduces a unique CRTC value so that Present can detect
the first time a window is a PresentPixmap destination and set the MSC
offset to zero, rather than using the fake MSC value as the previous
window MSC.

If the window is destroyed, then we've got cleanup work to do, even if
the vblank has already been executed -- we need to clear the window
pointer so that we don't try to deliver events to it.
Leaving it on the window list meant that when walking that list, we
need to know whether the vblank is waiting to be executed or waiting
for the flip to complete, so a new 'queued' flag was added to the
vblank to distinguish between the two states.
