[PATCH xf86-video-nested v4 03/11] Add preliminary support for screen options "Fullscreen" and "Output" in xorg.conf

This patch introduces support for new screen options in xorg.conf, namely:
"Fullscreen" and "Output". They are expected to work exactly as command-line
options -fullscreen and -output for Xephyr, allowing to open nested Xorg
window in fullscreen mode (restricted to given host X server output
if option "Output" is set).
In order to achieve this, NestedClientCheckDisplay() needs to be extended
to allow collecting fullscreen geometry from host X server while
checking if it's ready for connections, which has to be implemented
on each backend client.
NestedClientCreateScreen() also was extended to include a boolean
argument that tells backend client if it needs to set appropriate fullscreen
hint for nested Xorg window.
