216bdbc735 removed the SetRootClip call in the XWayland output-hotplug
handler when running rootless (e.g. as a part of Weston/Mutter), since
the root window has no storage, so generating exposures will result in
writes to invalid memory.
Unfortunately, preventing the segfault also breaks sprite confinement.
SetRootClip updates winSize and borderSize for the root window, which
when combined with RRScreenSizeChanged calling ScreenRestructured,
generates a new sprite-confinment area to update it to the whole screen.
Removing this call results in the window geometry being reported
correctly, but winSize/borderSize never changing from their values at
startup, i.e. out of sync with the root window geometry / screen
information in the connection info / XRandR.
This patch introduces a hybrid mode, where we update winSize and
borderSize for the root window, enabling sprite confinement to work
correctly, but keep the clip emptied so exposures are never generated.

This adds support to Xwayland to try and use OpenGL core
profile for glamor first.
v1.1: use version defines.
v2: let glamor work out core profile itself.

Otherwise the server may try to draw onto the root window when closing
down, but when running rootless the root window has no storage thus
causing a memory corruption.

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.

One less layering violation (EGL should call glamor, if anything, not
the other way around).
v2: Move glamor.c's DestroyPixmap wrapping up above the
glamor_egl_screen_init() call, since glamor.c's DestroyPixmap
needs to be the bottom of the stack (it calls fb directly and
doesn't wrap). Caught by Michel.

There were three paths that called eglDestroyImageKHR:
* The front buffer
* The intel driver's flip buffer
* pixmaps under DRI3
This patch unifies the second two by having glamor_destroy_pixmap
always destroy any associaged EGL image. This allows us to stop
storing the back_pixmap pointer in glamor as that was only used to
make sure that buffer was freed at server reset time.
v2: check for valid pixmap_priv before using it in
glamor_egl_destroy_pixmap_image
