[ANNOUNCE] xf86-video-intel 2.20.17

[Chris Wilson]

Release 2.20.17 (2012-12-26)
============================
A minor update to prepare for co-operating with the kernel over managing
stability on 830gm/845g. On this pair of chipsets, the kernel will perform
an extra copy of the batchbuffer into reserved memory, which prevents them
from randomly dying. However, that extra copy does have a noticeable
impact upon throughput, so we also have a mechanism for userspace to
opt-out of the kernel workaround and take responsibility for ensuring its
batches are coherent.

 * Build fixes against xorg-1.14
   https://bugs.freedesktop.org/show_bug.cgi?id=58552
   https://bugs.freedesktop.org/show_bug.cgi?id=58406

 * Fixed the origin of cropped (textured) video windows (Xv and XvMC)
   https://bugs.freedesktop.org/show_bug.cgi?id=23033

 * Fix potential corruption when using images larger than ~1GiB
