Olivier Fourdan f43207c1c4 glamor: restore vfunc handlers on init failure 
In glamor_init(), if the minimum requirements are not met, glamor may
fail after setting up its own CloseScreen() and DestroyPixmap()
routines, leading to a crash when either of the two routines is called
if glamor failed to complete its initialization, e.g:

  (EE) Backtrace:
  (EE) 0:  Xwayland (OsSigHandler+0x29)
  (EE) 1: /lib64/libpthread.so.0 (__restore_rt+0x0)
  (EE) 2: Xwayland (glamor_sync_close+0x2a)
  (EE) 3: Xwayland (glamor_close_screen+0x52)
  (EE) 4: Xwayland (CursorCloseScreen+0x88)
  (EE) 5: Xwayland (AnimCurCloseScreen+0xa4)
  (EE) 6: Xwayland (present_close_screen+0x42)
  (EE) 7: Xwayland (dix_main+0x4f9)
  (EE) 8: /lib64/libc.so.6 (__libc_start_main+0xf1)
  (EE) 9:  Xwayland (_start+0x2a)

Restore the previous CloseScreen() and DestroyPixmap() vfunc handlers in
case of failure when checking for the minimum requirements, so that if
any of the requirement is not met we don't leave the CloseScreen() and
DestroyPixmap() from glamor handlers in place.

					X Server

The X server accepts requests from client applications to create windows,
which are (normally rectangular) "virtual screens" that the client program
can draw into.

Windows are then composed on the actual screen by the X server
(or by a separate composite manager) as directed by the window manager,
which usually communicates with the user via graphical controls such as buttons
and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the
following article:
http://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the
Xorg mailing list:

Please submit bug reports to the Xorg bugzilla:
