Continuing the small bugfix releases, the only real feature is initial
enabling for Haswell for the purpose of rendering verification and
validation - by no means is it complete!
Bugs fixed since 2.20.3:
* Some potential errors along failure paths found by a static analyser
with the help of Zdenek Kablac.
* Eliminate zero-sized rectangles from PolyFillRectangles as the code
assumes that they did not exist and so caused corruption.
* Remove the UXA warning for failing to tile the front buffer if it is
disallowed by hardware, and so expected.
* Fix the validation of the XV pipe parameter.
* Fix 8x8 tiled pattern fills
https://bugs.freedesktop.org/show_bug.cgi?id=53353
* Fix compile failure when using --with-builderstring
* Restore w/a flush for gen4 fill/copy/video, fortunately rare
operations as at least for fill/copy we prefer to use the BLT.
https://bugs.freedesktop.org/show_bug.cgi?id=53119
* Restore preferred use of the RENDER ring for SNB+ DRI copies.

i810: Query PortPriv for the surface properties
sna/gen2: Add break rather than fallthrough
sna: Check for failure to pin the front buffer
test/dri2: Discard error returns from _XReply
uxa: Check for failed mmapping of the scanout
