Introduce support for Present's window flip mode. The support is not yet
complete, but works reasonable well for the most important use case, that
is fullscreen applications.
We take a Present flip and if the xwl_window->window has the same dimensions
as the presenting window, the flip is represented by a wl_buffer and attached
to the main wl_surface of the xwl_window.
After commit we are listening for the sync callback in order to tell Present,
that the pixmap flip is not longer pending, for the frame callback in order
to update the msc counter and for the buffer release callback in order to tell
Present that the pixmap is idle again.
The following functionality is missing from this patch:
* (slowed down) flips in case the compositor is not sending frame callbacks,
* queuing events to MSC times,
* per window flips for child windows with smaller size than the xwl_window.
To make use of this functionality Xwayland must run rootless and with
Glamor/GBM.

This adds support for RandR CRTC/Output leases through the modesetting
driver, creating a lease using new kernel infrastructure and returning
that to a client through an fd which will have access to only those
resources.
v2: Restore CRTC mode when leases terminate
When a lease terminates for a crtc we have saved data for, go
ahead and restore the saved mode.
v3: Report RR_Rotate_0 rotations for leased crtcs.
Ignore leased CRTCs when selecting screen size.
Stop leasing encoders, the kernel doesn't do that anymore.
Turn off crtc->enabled while leased so that modesetting
ignores them.
Check lease status before calling any driver mode functions
When starting a lease, mark leased CRTCs as disabled and hide
their cursors. Also, check to see if there are other
non-leased CRTCs which are driving leased Outputs and mark
them as disabled as well. Sometimes an application will lease
an idle crtc instead of the one already associated with the
leased output.
When terminating a lease, reset any CRTCs which are driving
outputs that are no longer leased so that they start working
again.
This required splitting the DIX level lease termination code
into two pieces, one to remove the lease from the system
(RRLeaseTerminated) and a new function that frees the lease
data structure (RRLeaseFree).
v4: Report RR_Rotate_0 rotation for leased crtcs.
v5: Terminate all leases on server reset.
Leases hang around after the associated client exits so that
the client doesn't need to occupy an X server client slot and
consume a file descriptor once it has gotten the output
resources necessary.
Any leases still hanging around when the X server resets or
shuts down need to be cleaned up by calling the kernel to
terminate the lease and freeing any DIX structures.
Note that we cannot simply use the existing
drmmode_terminate_lease function on each lease as that wants
to also reset the video mode, and during server shut down that
modesetting: Validate leases on VT enter
The kernel doesn't allow any master ioctls to run when another
VT is active, including simple things like listing the active
leases. To deal with that, we check the list of leases
whenever the X server VT is activated.

Turns out that the kernel DRM ioctl handling returns EINVAL
instead of ENOTTY if one tries to call the new drmCrtcGetSequence()
or drmCrtcQueueSequence() ioctl's introduced in Linux 4.15 on an
older kernel where they are missing. This causes the fallback code
not to fall back to the old drmWaitVblank() ioctl and thereby
failure of vblank stuff.
E.g., on Linux 4.13, glxgears -info runs unthrottled at 10000 fps
instead of 60 fps. Also breakage of OML_sync_control extension.
Check for errno != EINVAL before setting has_queue_sequence = TRUE.
Additionally in case of supported drmCrtcQueueSequence(), set
has_queue_sequence = TRUE on success, or we might get at
least a temporary failure in ms_queue_vblank().
One slight ambiguity is that we can also get EINVAL if
drm_crtc_vblank_get() fails in the kernel, so if that
happened at first invocation of the new api, we'd fall
back to drmWaitVblank() and then fail there, instead of
failing in the new api, but the end result would be the
same.

The big change here is MakeCurrent and context tag tracking. We now
delegate context tags entirely to the vnd layer, and simply store a
pointer to the context state as the tag data. If a context is deleted
while it's current, we allocate a fake ID for the context and move the
context state there, so the tag data still points to a real context. As
a result we can stop trying so hard to detach the client from contexts
at disconnect time and just let resource destruction handle it.
Since vnd handles all the MakeCurrent protocol now, our request handlers
for it can just be return BadImplementation. We also remove a bunch of

up sending xdg_output before wl_seat. xwl_screen_get_default_seat()
makes the naïve assumption that we always have a valid seat, we end up
returning a pointer to the empty list itself instead of an actual seat
and causing ourselves to segfault.
So, actually return NULL in xwl_screen_get_default_seat() if the seat
list is empty, and skip any pointer confinement processing in
xwl_cursor_confined_to() when we don't have a seat setup yet.

This is a rare occurrence of a crash in Xwayland for which I don't have
the reproducing steps, just a core file.
The backtrace looks as follow:
#0 raise () from /usr/lib64/libc.so.6
#1 abort () from /usr/lib64/libc.so.6
#2 OsAbort () at utils.c:1361
#3 AbortServer () at log.c:877

#10 BlockHandler () at dixutils.c:388
#11 WaitForSomething () at WaitFor.c:219
#12 Dispatch () at dispatch.c:422
#13 dix_main () at main.c:287
The crash is caused by dereferencing “xwl_pixmap->buffer” in
xwl_glamor_pixmap_get_wl_buffer() because “xwl_pixmap” is NULL.
Reason for this is because the corresponding pixmap is from the root
window and xwayland is rootless by default.
This can happen if the window was mapped, redirected, damaged and
unredirected immediately, before the damage is processed by Xwayland.
Make sure to remove the dirty window from the damage list on unrealize
to prevent this from happening.

The xdg-output protocol aims at describing outputs in way which is
more in line with the concept of an output on desktop oriented systems.
For now it just features the position and logical size which describe
the output position and size in the global compositor space.
This is however much useful for Xwayland to advertise the output size
and position to X11 clients which need this to configure their surfaces
in the global compositor space as the compositor may apply a different
scale from what is advertised by the output scaling property (to achieve
fractional scaling, for example).
This was added in wayland-protocols 1.10.

If an X11 app draws a little here, some there, and a tiny bit in the
opposite corner, using RegionExtents for the damage to be sent to the
Wayland compositor will cause massive over-damaging.
However, we cannot blindly send an arbitrary number of damage
rectangles, because there is a risk of overflowing the Wayland
connection. If that happens, it triggers an abort in libwayland-client.
Try to be more accurate with the damage by sending up to 256 rectangles
per window, and fall back to extents otherwise. The number is completely
arbitrary.

The install rule of Xorg.wrap is currently a dependency of the
install-data target instead of the install-exec target. The build also
uses install-exec-hook to change the ownership and set the SUID bit on
the Xorg.wrap binary. The problem is that install-exec-hook is only
ordered respective to the install-exec target, the rules of install-data
may or may not have been executed.
If install-exec-hook runs before the Xorg.wrap binary is in place,
a message similar to the following will be present in the build log:
chown: cannot access '/pkgdir/usr/lib/xorg-server/Xorg.wrap': No such file or directory
make[6]: [Makefile:1151: install-exec-hook] Error 1 (ignored)
All that needs to be done is to change the name of the program variable
to contain 'exec' for the install rule to depend on the install-exec
target.
Excerpt from the Automake manual, chapter 12.2 The Two Parts of Install:
"Any variable using a user-defined directory prefix with ‘exec’ in the
name (e.g., myexecbin_PROGRAMS) is installed by install-exec. All other
user-defined prefixes are installed by install-data."

This was added in ~2004 for the sis driver, to detect whether it could
use SSE for memcpy. Charmingly, the code to check whether that feature
exists in the server is:
#if XORG_VERSION_CURRENT >= XORG_VERSION_NUMERIC(6,8,99,13,0)
#define SISCHECKOSSSE /* Automatic check OS for SSE; requires SigIll facility */
#endif
Which means it has never worked in any modular server release.
A less gross way to do this is to check for SSE support with getauxval()
or /proc/cpuinfo or similar. Since no driver is using the existing
intercept mechanism, drop it.
