[PULL] security fixes; update DoChangeGC/ChangeGC to dixChangeGC

[Jamey Sharp]

I rebased these to apply against master instead of depending on cleanups
that nobody has reviewed yet. I hope that's alright.

The following changes since commit 59857ee5da5f1f3f4900292581b9586477513211:
  Keith Packard (1):
        Merge remote branch 'dottedmag/for-keithp'

are available in the git repository at:

  git://people.freedesktop.org/~jamey/xserver for-keith

Jamey Sharp (4):
      doPolyText needs UseAccess to each font, not ReadAccess.
      Kill DoChangeGC in favor of dixChangeGC.
      Kill ChangeGC in favor of dixChangeGC.
      CreateGC: Pass current client on to ChangeGC.
