The multi-crtc cursor code in hw/xfree86/modes holds a reference to the
current cursor. This reference must be correctly ref counted so the cursor
is not freed out from underneath this code.
xf86_reload_cursors is supposed to be called from the crtc mode setting
commit hook; as that happens during server initialization, check for this
case.

This moves most of the cursor management code out of the intel driver and
into the general server code. Of course, the hope is that this code will be
useful for other driver writers as well.
Check out xf86Crtc.h for the usage information, making sure you add the
needed hooks to the crtc funcs structure for your driver.
