Skipped present pixmap calls were not setting the mode to
PresentCompleteModeSkip for skipped operations.

Presents which are not marked 'queued' and are in the window present
list are waiting for the flip event; discarding those won't work very
well (it'll end up trashing displayed content for the next frame), so
skip over those when looking for duplicate frame presents

Check for Async flag and execute immediately if set, otherwise wait
for the next appropriate vblank before copying.

Newly created windows inherit the pixmap of their parent, similarly,
reparenting a tree inherits the pixmap of the destination tree.
Making present preserve the invariant that unredirected windows always
have the same pixmap as their parent ensures that the above cases work
correctly.
v2: name the recursive function to 'set_tree_pixmap' instead of 'set_window_pixmap'

This makes sure that things like software cursors continue to work
while the screen is flipped.

If the driver doesn't have the necessary hooks for Present, then the
target_crtc needs to be set to NULL to make sure the extension uses
the present_fake code.

This makes other drawing to the window appear on the screen.
Note that no child windows can be affected because only full-screen
windows are eligible for flipping, and so we only need to set pixmap
for the window itself.

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.

When an application provides two pixmaps for the same MSC, the
previous one is skipped. This just dumps out some information at that point

unflip happens after the clip lists have been updated, so instead of
smashing the whole screen and drawing over other windows, just draw to
the original flip window; it'll have the right clip list and so the
copy will work just fine.

This eliminates dereferencing freed window pointers when there is a
flip for that window in progress. The flip will complete, and then
immediately get undone (as we can't stop an in-progress flip).
Remove the vblank->window_destroyed field as we can signal this with
vblank->window == NULL instead.
Change check to vblank->window == NULL in:
present_flip_notify
Add check for vblank->window == NULL in:
present_vblank_notify
present_execute
present_flip_notify was also using vblank->window->drawable.pScreen,
so stop doing that and use vblank->screen instead.

We use event_id 0 to mean 'no such event'; if a driver sends us that
event_id, make sure we don't accidentally match it.

A client destroying objects in the middle of an unflip can end up
having the screen flip window or fence set to NULL in the unflip
notify path. Check for these and don't try to use those objects.
