Make sure we're not scanning out any fbs with fancy modifiers when
we try to light up new displays. This is already the case in cases
where the screen gets resized, but in cases where that doesn't happen
it might be possible for the modeset(s) to fail due to watermark/etc.
constraints imposed by the fancy modifiers. We can avoid that by
making sure everything gets unflipped before the modeset.

Adding new flip reasons after the TearFree ones would break the assumption
that `reason >= PRESENT_FLIP_REASON_DRIVER_TEARFREE` implies either of the
TearFree reasons. Document this in the PresentFlipReason enum in order to
save someone a very bad headache in the future.

When a driver uses TearFree to flip all frames synchronized to the vblank
interval, Present has no idea and still assumes that each presentation
occurs immediately upon copying its damages to the primary scanout. This
faulty assumption breaks presentation timestamping, potentially leading to
A/V de-synchronization and dropped frames.
Present needs to have some awareness of a driver using TearFree so that it
can know when each presentation actually becomes visible on the screen.
Teach Present about drivers using TearFree by expanding PresentFlipReason
to allow drivers to export some contextual info about TearFree when Present
cannot page-flip directly anyway.
PRESENT_FLIP_REASON_DRIVER_TEARFREE indicates that a driver has TearFree
enabled but doesn't have a TearFree flip currently pending.
PRESENT_FLIP_REASON_DRIVER_TEARFREE_FLIPPING indicates that a driver has a
TearFree flip currently pending.

Currently, when main hardware screen is powered-off,
X server initializes fake screen's timer with
1 second update interval.
Streaming software like Nomachine or Vnc, as well as
desktop input automation suffers from it, since it
will forever be stuck on 1 fps until the display is
turned back on.
This commit adds command line option -fakescreenfps <int>
that allows the user to change the default fake screen
timer.

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)

Notifying Present about events' states was done prior with the single function
present_wnmd_event_notify just like in screen mode. But it is more intelligible
if at least in window mode we make use of three different functions with names
that directly indicate what their purpose is:
* present_wnmd_event_notify only for queued events feedback.
* present_wnmd_flip_notify for when a presentation occured (flip).
* present_wnmd_idle_notify for when the Pixmap of the event can be reused.
This is an API-breaking change in regards to window mode. DDX written against
the previous version won't work anymore. It is assumed that there only exists
the XWayland DDX at the moment using the window mode such that this is not an
issue for the overall ecosystem.

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.

If it is because of unsupported buffer format/modifier,
a PresentCompleteNotify event is sent to the client with

Present didn't provide the 'kind' argument to the
present_complete_notify hook that GLX uses to construct
GLX_BufferSwapComplete events, so GLX was reporting events for
PresentCompleteKindMSC notifications, which resulted in duplicate
GLX_BufferSwapComplete events and crashes in clutter.
