ab9837cc6a xwayland: Update screen size on output removal
When unplugging an output, it's still listed in xrandr and the size
of the root window still includes the removed output.

The RR output should be destroyed when its Wayland counterpart is
destroyed and the screen dimensions must be updated in both the done
and the destroy handlers.

07941a50a5 xwayland: Always update the wl_pointer cursor on pointer focus
In Wayland, a client (in this case XWayland) should set the cursor
surface when it receives pointer focus. Not doing this will leave the
curser at whatever it was previously.

When running on XWayland, the X server will not be the entity that
controls what actual pointer cursor is displayed, and it wont be notified
about the pointer cursor changes done by the Wayland compositor. This
causes X11 clients running via XWayland to end up with incorrect pointer
cursors because the X server believes that, if the cursor was previously
set to the cursor C, if we receive Wayland pointer focus over window W
which also has the pointer cursor C, we do not need to update it. This
will cause us to end up with the wrong cursor if cursor C was not the
same one that was already set by the Wayland compositor.

This patch works around this by, when receiving pointer focus, getting
the private mipointer struct changing the "current sprite" pointer to
an invalid cursor in order to trigger the update path next time a cursor
is displayed by dix.

Otherwise the server may try to draw onto the root window when closing

51984dddfc glamor: Delay making pixmaps shareable until we need to.
If a pixmap isn't getting exported as a dmabuf, then we don't need to
make an EGLImage/GBM bo for it.  This should reduce normal pixmap
allocation overhead, and also lets the driver choose non-scanout
formats which may be much higher performance.

On Raspberry Pi, where scanout isn't usable as a texture source, this
improves x11perf -copypixwin100 from about 4300/sec to 5780/sec under
xcompmgr -a, because we no longer need to upload our x11perf window to
a tiled temporary in order to render it to the screen.

v2: Just use pixmap->usage_hint instead of a new field.  Drop the
    changes that started storing gbm_bos in the pixmap priv due to
    lifetime issues.
v3: Fix a missing gbm_bo_destroy() on the pixmap-from-fd success path.

I assume this was a workaround for an old, broken, closed driver.  The
driver doesn't get to throw away rendering just because the rendering
context's shared-across-processes render target is getting freed from
the local address space.  If the rendering isn't to a shared render
target, then we *do* want to throw away the rendering to it.

9a5972801f glamor: Fix segfault in fallback picture uploading.
If the source/mask pixmap is a pixmap that doesn't have an FBO
attached, and it doesn't match the Render operation's size, then we'll
composite it to a CPU temporary (not sure why).  We would take the
PictFormatShort from the source Picture, make a pixmap of that depth,
and try to look up the PictFormat description from the depth and the
PictFormatShort.  However, the screen's PictFormats are only attached
to the screen's visuals' depths.  So, with an x2r10g10b10 short format
(depth 30), we wouldn't find the screen's PictFormat for it
(associated with depth 32).

Instead of trying to look up from the screen, just use the pFormat
that came from our source picture.  The only time we need to look up a
PictFormat when we're doing non-shader gradients, which we put in
a8r8g8b8.

50c1671647 os: make sure the clientsWritable fd_set is initialized before use
In WaitForSomething(), the fd_set clientsWritable may be used
unitialized when the boolean AnyClientsWriteBlocked is set in the
WakeupHandler(). This leads to a crash in FlushAllOutput() after
x11proto's commit 2c94cdb453bc641246cc8b9a876da9799bee1ce7.

The problem did not manifest before because both the XFD_SIZE and the
maximum number of clients were set to 256. As the connectionTranslation
table was initalized for the 256 clients to 0, the test on the index not
being 0 was aborting before dereferencing the client #0.

As of commit 2c94cdb453bc641246cc8b9a876da9799bee1ce7 in x11proto, the
XFD_SIZE got bumped to 512. This lead the OutputPending fd_set to have
any fd above 256 to be uninitialized which in turns lead to reading an
index after the end of the ConnectionTranslation table. This index would
then be used to find the client corresponding to the fd marked as
pending writes and would also result to an out-of-bound access which
would usually be the fatal one.

Fix this by zeroing the clientsWritable fd_set at the beginning of
WaitForSomething(). In this case, the bottom part of the loop, which
would indirectly call FlushAllOutput, will not do any work but the next
call to select will result in the execution of the right codepath. This
is exactly what we want because we need to know the writable clients
before handling them. In the end, it also makes sure that the fds above
MaxClient are initialized, preventing the crash in FlushAllOutput().

Thanks to everyone involved in tracking this one down!
