Add a fd_from_pixmap (singular) hook to go with fds_from_pixmap, which
will ensure that the pixmap is allocated without modifiers and is thus
exportable to non-modifier-aware clients.
This makes it possible to run a compositing manager on an old GLX/EGL

If the libEGL we are using has eglGetPlatformDisplayEXT, yet it still
returns NULL, then this very likely means that it does not support the
type (e.g. EGL_PLATFORM_GBM_MESA) passed in, and then returning NULL is
the right thing to do.
This avoids falling back to an eglGetDisplay() implementation which does
not understands the passed in gbm handle, treats it as a pointer to
something else completely, followed by a crash sooner or later.
Specifically this fixes using the nvidia binary driver, with nvidia's
libEGL + the modesetting driver on a secondary GPU crashing inside
glamor_egl_init() sometimes.

When a GPU gets hotplugged while X is already running, glamor_egl_init()
gets called and changes the current egl context, without updating
lastGLContext, potentially causing the next glamor call on another GPU to
run in the wrong context.
This causes glamor to e.g. crash in the next glamor_create_pixmap() call
(called through the master's screen->CreatePixmap), note this is not the
only troublesome entry point I've seen other backtraces when using a
compositing window manager.
Set lastGLContext to NULL to force the next glamor_make_current() call
to set the right context.
Note that we cannot use glamor_make_current() here to replace the
eglMakeCurrent() call and update lastGLContext for us because
glamor_make_current takes a glamor_priv struct as argument and that
has not been created yet when glamor_egl_init() gets called.

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.
