[Intel-gfx] [ANNOUNCE] xf86-video-intel 2.21.15

[Chris Wilson]

Release 2.21.15 (2013-08-21)
============================
Some build fixes for the BSDs and alternate compiler, and conflicting
configure options and a critcial fix for some PRIME setups.

 * Don't fail to configure if DRI1 is not available and the user asks
   for both DRI and KMS-only
   [Regression from 2.21.14]

 * Lots of miscellaneous fixes for older gcc, other compilers and BSD.

 * Initial framework support for hosted X.

 * Improve transition from fbcon to X with multiple outputs and extended
   desktops.

 * Ensure the framebuffer exists before checking it against the CRTC
   constraints.

   [Regression from 2.21.10]

 * Add RGB overlay support for Ironlake and later.

 * Don't release the overlay buffer too early, i.e. before the client
   disables the Xv image.

 * Tweak the ring switching logic to reduce use of semaphores on
   Sandybridge and later - a delicate balancing act between trying to
   use the faster engine for the task and preventing concurrent use of
   multiple rings.
