[ANNOUNCE] xf86-video-intel 2.21.5

[Chris Wilson]

Release 2.21.5 (2013-03-21)
===========================
Haswell reintroduces a command to load the scanline window from the
command stream and so requires its own specialised wait-for-vsync routine
- failure to do so was then causing hangs when trying to do tearfree video
or use a compositor.

 * Prevent buffer leak if a non-fullscreen Window is closed with multiple
   pending swap events.

 * Fix offset transformation for fallback gradient paths.

 * Prevent Glamor from crashing if misconfigured.
   Thanks to Michel Dänzer.

 * Prevent UXA from crashing if torn down during PreInit.
   Thanks to Aaron Plattner.

 * Prevent miscompilation with different functional units having different
   compiler flags. Some functions were expected to be inlined and so
   recompiled with the current target. However, some compilers were
   choosing to emit subroutine calls instead without noticing that the
   ABI was different between the caller and callee - causing corruption.

 * Fix rendering of CompositeTriFan with recent Xorg.

 * Apply the video src-offset fix highlighted in the last release!
   A typo prevented the fix from working for gen4+.

 * Fix rendering of multiple glyphs to very large destination surfaces

 * Fix scanline waits for Haswell
