Summary: This is is based on https://reviews.facebook.net/D15027. It's not finished but I would like to give a prototype to avoid arena over-allocation while making better use of the already allocated memory blocks. Instead of check approximate memtable size, we will take a deeper look at the arena, which incorporate essential idea that @sdong suggests: flush when arena has allocated its last and the last is "almost full" Test Plan: N/A Reviewers: haobo, sdong Reviewed By: sdong CC: leveldb, sdong Differential Revision: https://reviews.facebook.net/D15051

Summary: @igor pointed out that there is a potential data race because of the way we use the newly introduced LogBuffer. After "bg_compaction_scheduled_--" or "bg_flush_scheduled_--", they can both become 0. As soon as the lock is released after that, DBImpl's deconstructor can go ahead and deconstruct all the states inside DB, including the info_log object hold in a shared pointer of the options object it keeps. At that point it is not safe anymore to continue using the info logger to write the delayed logs. With the patch, lock is released temporarily for log buffer to be flushed before "bg_compaction_scheduled_--" or "bg_flush_scheduled_--". In order to make sure we don't miss any pending flush or compaction, a new flag bg_schedule_needed_ is added, which is set to be true if there is a pending flush or compaction but not scheduled because of the max thread limit. If the flag is set to be true, the scheduling function will be called before compaction or flush thread finishes. Thanks @igor for this finding!

Summary: (1) Fix SanitizeOptions() to also check HashLinkList. The current dynamic case just happens to work because the 2 classes have the same layout. (2) Do not delete SliceTransform object in HashSkipListFactory and HashLinkListFactory destructor. Reason: SanitizeOptions() enforces prefix_extractor and SliceTransform to be the same object when Hash**Factory is used. This makes the behavior strange: when Hash**Factory is used, prefix_extractor will be released by RocksDB. If other memtable factory is used, prefix_extractor should be released by user.

Summary: Now while the background thread is picking compactions, it writes out multiple info_logs, especially for universal compaction, which introduces a chance of waiting log writing in mutex, which is bad.
