Subject: [PATCH xserver] xephyr: Check for host XVideo support before trying
to use it
Otherwise xcb will treat our attempt to send xv requests as a connection
error (quite reasonably: we're asking it to emit a request for which
there is no defined major opcode), and we'll die quietly the first time
we hit KdBlockhandler.
