[ANNOUNCE] libdrm 2.4.21

[Eric Anholt]

Getting new intel API out the door.  The two major changes:
1) media ring support on kernel 2.6.35 for doing media decode on G45+
2) Reduced memory allocation for BO cached objects -- saves about 1/4 of
   the graphics memory on workloads I tested on Ironlake and 945GM.
