We can acknoledge seeks before preparation finished immediately now, because ExoPlayerImpl won't leave the masking state until the first prepare operation is processed. As a side effect, it also cleans up the responsibility of the callbacks. Prepares are always acknowledged with a SOURCE_INFO_REFRESHED, while seeks are always acknowledged with a SEEK_ACK. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=177144089
