avcodec/vp9: Join extradata buffer pools Up until now each thread had its own buffer pool for extradata buffers when using frame-threading. Each thread can have at most three references to extradata and in the long run, each thread's bufferpool seems to fill up with three entries. But given that at any given time there can be at most 2 + number of threads entries used (the oldest thread can have two references to preceding frames that are not currently decoded and each thread has its own current frame, but there can be no references to any other frames), this is wasteful. This commit therefore uses a single buffer pool that is synced across threads.
