Update to 1.3.3:

Time for a release before the accumulated patches are old enough to vote.
Two new requirements: libX11 1.6 and a C89 preprocessor.

Alan Coopersmith (4):
      Replace sprintf with snprintf when looking up extension error strings
      Require ANSI C89 pre-processor, drop pre-C89 token pasting support
      Remove fallback for _XEatDataWords, require libX11 1.6 for it
      XeviGetVisualInfo: Free & clear *evi_return, not evi_return pointer

Keith Packard (1):
      Xge: remove warning messages about missing Xge extension event translations

Nathan Kidd (1):
      Stricter event error checking

Peter Hutterer (1):
      libXext 1.3.3
