Enrico Weigelt, metux IT consult 0ccb78b096 present: unexport present_extension_init()
It's not called by drivers/modules, so no need to keep it exported.

Enrico Weigelt, metux IT consult fb696a7d7b rename old symbol PANORAMIX to XINERAMA
PANORAMIX was the original working title of the extension, before it became
official standard. Just nobody cared about fixing the symbols to the official
naming.

For backwards compatibility with drivers, the old PANORAMIX symbol will
still be set.

Ville Syrjälä 899c87af1f modesetting: unflip before any setcrtc() calls
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.

v2: make poll timeout infinite
    s/in_modeset/pending_modeset/
    deal with tearfree fallout (goto no_flip)

Adam Jackson 462b06033e present: Send a PresentConfigureNotify event for destroyed windows
This enables fixing a deadlock case on the client side, where the client
ends up blocked waiting for a Present event that will never come because
the window was destroyed. The new PresentWindowDestroyed flag allows the
client to avoid blocking indefinitely.

Michel Dänzer b6419359b6 present: Move present_wnmd.c contents to hw/xwayland/xwayland-present.c
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)

Michel Dänzer 1bdedc8dbb present/wnmd: Free flip_queue entries in present_wnmd_clear_window_flip
When present_wnmd_clear_window_flip is done, present_destroy_window
frees struct present_window_priv, and the events in the flip queue
become unreachable. So if we don't free them first, they're leaked.

Also drop the call to present_wnmd_set_abort_flip, which just sets a
flag in struct present_window_priv and thus can't have any observable
effect after present_destroy_window.

Michel Dänzer bc9dd1c71c present/wnmd: Keep pixmap pointer in present_wnmd_clear_window_flip
The comment was incorrect: Any reference held by the window (see
present_wnmd_execute) is in addition to the one in struct present_vblank
(see present_vblank_create). So if we don't drop the latter, the pixmap
will be leaked.

Keith Packard 627bce8089 present: Make window MSC offset 0 initially
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.

Keith Packard e5a188cb91 present: Signal destroyed flip window with vblank->window == NULL
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.
