7c7e4d4eb8
This patch allocated frame contexts outside VP9_COMMON. This allows multiple threads to share the same copy of frame contexts, and reduces the overhead. It also guarantees the correct update of these contexts during bitstream packing. This patch doesn't change encoding result. Change-Id: Ic181a2460b891d1d587278a6d02d8057b9dbd353
