Summary: Abstract out FlushProcess and take it out of DBImpl. This also includes taking DeletionState outside of DBImpl. Currently this diff is only doing the refactoring. Future work includes: 1. Decoupling flush_process.cc, make it depend on less state 2. Write flush_process_test, which will mock out everything that FlushProcess depends on and test it in isolation Test Plan: make check Reviewers: rven, yhchiang, sdong, ljin Reviewed By: ljin Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D27561
