glamor: Handle bitplane in glamor_copy_fbo_cpu

Browse Source 
This can significantly speed up at least some CopyPlane cases, e.g.
indirectly for stippled fills.

v2:
* Make temporary pixmap the same size as the destination pixmap
  (instead of the destination drawable size), and fix coordinate
  parameters passed to fbCopyXtoX and glamor_upload_boxes. Fixes
  incorrect rendering with x11perf -copyplane* and crashes with the
  xscreensaver phosphor hack.
v3:
* Make the change a bit more compact and hopefully more readable by
  re-using the existing src_* locals in the bitplane case as well.
