Igor Canadi	f1c8862479	Fix data race #1 ... Summary: This is first in a series of diffs that fixes data races detected by thread sanitizer. Here the problem is that we call Ref() on a column family during a single-threaded write, without holding a mutex. Test Plan: TSAN is no longer complaining about LevelLimitReopen.

Igor Canadi	3d9e6f7759	Push model for flushing memtables ... Summary: When memtable is full it calls the registered callback. That callback then registers column family as needing the flush. Every write checks if there are some column families that need to be flushed. This completely eliminates the need for MakeRoomForWrite() function and simplifies our Write code-path. There is some complexity with the concurrency when the column family is dropped. I made it a bit less complex by dropping the column family from the write thread in https://reviews.facebook.net/D22965. Let me know if you want to discuss this. Test Plan: make check works. I'll also run db_stress with creating and dropping column families for a while.
