[ANNOUNCE] xf86-video-intel 2.21.6

[Chris Wilson]

Release 2.21.6 (2013-04-06)
===========================
A surprising highlight of this release is a little refresh to the KMS
support for OpenBSD. OpenBSD now has its own KMS implementation which is
mostly compatible with the interface in Linux, with one or two tweaks
supplied by Mark Kettenis. This release continues to cleanup behaviour
for Haswell.

 * Workaround a failure by the xserver to invalidate DRI buffers
   following a pixmap change for XComposite redirection.
   https://bugs.freedesktop.org/show_bug.cgi?id=62614

 * Fix computation of clip extents for stippling
   https://bugs.freedesktop.org/show_bug.cgi?id=62618

 * Support KMS on OpenBSD, by Mark Kettenis

 * Clean up sockets upon CloseScreen (making ourselves better behaved
   for muxed setups).

 * Fix the tests for AVX/AVX2 support in CPUID and remember to check for
   OS support as well.

 * Report a monotonic UST value for undisplayed drawables rather than 0
   by Daniel Kurtz

 * Fix video playback on gen4 through a complex clip (more gen4 GPU woes)
