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 extension was using the name CARD64 to represent 64-bit values,
with a #define from CARD64 to XSyncValue, a struct with a pair of

instead.

hasn't been built yet. The unit tests are also not done.
The intent is to build this as a complete replacement for the
autotools system, then eventually replace autotools. meson is faster
to generate the build, faster to run the bulid, shorter to write the
build files in, and less error-prone than autotools.

We are no longer using the present_flip_queue list only for presents
which have already been submitted to the driver for page flipping, but
also for those which we are queueing up to be flipped later, marked
with vblank->queued == TRUE. We were incorrectly calling
present_flip_notify for such entries, failing the assertion in
present_flip_notify (or presumably resulting in other undesirable
behaviour with assertions disabled).
Reproduction recipe: Run the JavaFX test case referenced by
https://bugs.freedesktop.org/show_bug.cgi?id=98831#c6 and alt-tab out
of it while it's fullscreen. May take a few attempts to hit the
assertion failure.

From the Present extension specification:
An event context is associated with a specific window; using
an existing event context with a different window generates
a Match error.
If eventContext specifies an existing event context, then if
eventMask is empty, PresentSelectInput deletes the specified
context, otherwise the specified event context is changed to
select a different set of events.
If eventContext is an unused XID, then if eventMask is empty
no operation is performed. Otherwise, a new event context is
created selecting the specified events.
Without this change, there's no way for a client to explicitly change
or destroy an existing event mask entry. Trying to do so as specified
above would just result in a protocol error.
v2: (Keith Packard)
* Use dixLookupResourceByType instead of walking window_priv->events
* Return BadMatch if the existing event context is associated with a
different window or client
* Call LEGAL_NEW_RESOURCE again when creating a new event context
* Drop invalid "leak fix"

A single provider can be both a offload and source slave at the same time,

Provider 0: id: 0x7b cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 2 associated providers: 1 name:modesetting

Provider 1: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 2 name:modesetting
Provider 2: id: 0x46 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 2 outputs: 5 associated providers: 2 name:modesetting
Not good. The problem is that the provider with id 0x46 now is on both
the output_slave_list and the offload_slave_list of the master screen.
This commit fixes this by unifying all 3 lists into a single slaves list.
Note that this does change the struct _Screen definition, so this is an ABI
break. I do not expect any of the drivers to actually use the removed / changed
fields so a recompile should suffice.

The flip queue currently only holds events submitted to the driver for
flipping, awaiting the completion notifier. It is short. We therefore
can speed up interrupt processing by keeping the small number of events
ready to be flipped on the end of the flip queue. By appending the
events to the flip_queue in the order that they become ready, we also
resolve one issue causing Present to display frames out of order.

This code was added to deal with the driver present hook failing, in
which case we need to wait for the next MSC before executing the
presentation.
However, it could also take effect in cases where the driver incorrectly
thinks the current MSC matches the target one (e.g. due to the kernel
interface only supporting 32-bit MSC values), in which case it could
result in the presentation getting requeued over and over.
To prevent such issues, check specifically for the target MSC
immediately following the current MSC.

Due to the way present currently works, we don't ever check with the
secondary adapters if we can flip at all.
We shouldn't flip if the secondary adapters are attached to the pixmap
currently, however using the current check_flip callback isn't possible
as it passes the Window to the driver (something we shouldn't be doing),
so the slave driver can never get it's own screen ptr back.
For now to fix the problem just block flips if we have any slaves
configured. We can fix the ABI up later, but this fix can be backported
to stable.

present_unflip may be called several times from present_check_flip_window
during the same unflip. We can only copy to the screen pixmap the first
time, otherwise we may scribble over other windows. The flip pixmap
contents don't get updated after the first time anyway.
Fixes at least the following problems, which were introduced by commit
806470b9 ("present: Copy unflip contents back to the Screen Pixmap"):
On xfwm4 without compositing, run glxgears and put its window into
fullscreen mode to start flipping. While in fullscreen, open the xfwm4
window menu by pressing Alt-Space. The window menu was invisible most
of the time because it was getting scribbled over by a repeated unflip
copy.
When switching a flipping window out of fullscreen, a repeated unflip
copy could leave artifacts of the flip pixmap on the desktop.
