[ANNOUNCE] xf86-video-intel 2.20.2

[Chris Wilson]

For the last 9 months, since 2.16.901, we have been shipping a driver that
does not work on IvyBridge GT1 systems (HD2500 graphics); we were telling
the GPU to use an invalid number of threads for the pixel shader and this
in turned caused the GPU to hang.

Also fixed since the last release just a few days ago:

* Support for the gmux backlight controller on Apple laptops
  https://bugs.freedesktop.org/show_bug.cgi?id=52423

* Fix X -configure not to list this driver as matching any Intel device,
  just the VGA class devices will do!

* A crash in SNA when repeatedly switching xrandr rotations

* Corruption in SNA observed in kwin on IvyBridge

      sna: Hold a reference to the full stipple pattern for repeated tiles
      sna: Flesh out tiled operations using the BLT
      sna: Refactor PutImage to avoid calling drawable_gc_flags() too early
      intel: Refactor the common chipset detection/override
      uxa: Pass the correct parameters to intel_detect_chipset()
      sna: Remove a surplus function
      sna: Use SETUP_BLT to reduce overheads for stippled BLT
      sna: Use SETUP_BLT to reduce overheads for tiled BLT
      uxa: Add Apple's gmux to the list of known preferred backlights
      sna: Reduce ping-pong for Composite with render disabled
      sna: Prefer platform backlight devices over firmware
      sna: Add 'gmux_backlight' to list of known devices for backwards compatability
      sna: Initialise single-shot tile offsets before use
      Assume all unknown chipsets are future gen
      sna/gen7: Remove duplicated constants
      sna/gen7: Move the PS thread count definition into the constant struct
      sna: Restore inplace upload for DRI compositors
      sna: Check for a NULL scanout after DPMS off with shadow enabled
      sna: Compile against xorg-1.10
      Limit PCI matching to VGA devices
      sna/dri: Implement fallback handling for CopyRegion whilst wedged
      sna: Allow DRI to force allocation of a GPU bo and backing pixmap
      sna/dri: Mark a flush required for any new DRI already on exec/dirty lists
      sna: Only recommend not to create bo for a pixmap whilst wedged
      sna: Force the damage on the DRI pixmap to be flushed to the GPU
      sna/video: Protect against attempting to use TexturedVideo whilst wedged
      sna/dri: Tidy fallback/normal CopyRegion
      sna/dri: Add an explanatory assertion
      sna/gen7: IVB requires a complete pipeline stall when changing blend modes
      sna/gen4: Bump thread counts
      sna/gen4: Tweak heuristics for render/blt usage
      Reduce maximum thread count for IVB GT1 to avoid spontaneous combustion
      sna/dri: Select the engine before emitting the wait
