Summary: This diff adds an option to specify whether PTHREAD_MUTEX_ADAPTIVE_NP will be enabled for the rocksdb single big kernel lock. db_bench also have this option now. Quickly tested 8 thread cpu bound 100 byte random read. No fast mutex: ~750k/s ops With fast mutex: ~880k/s ops Test Plan: make check; db_bench; db_stress Reviewers: dhruba CC: MarkCallaghan, leveldb Differential Revision: https://reviews.facebook.net/D11031

Summary: Implement ReadWrite locks for leveldb. These will be helpful to implement a read-modify-write operation (e.g. atomic increments). Test Plan: does not modify any existing code Reviewers: heyongqiang Reviewed By: heyongqiang CC: MarkCallaghan Differential Revision: https://reviews.facebook.net/D5787

- Replace raw slice comparison with a call to user comparator. Added test for custom comparators. - Fix end of namespace comments. - Fixed bug in picking inputs for a level-0 compaction. When finding overlapping files, the covered range may expand as files are added to the input set. We now correctly expand the range when this happens instead of continuing to use the old range. For example, suppose L0 contains files with the following ranges: F1: a .. d F2: c .. g F3: f .. j and the initial compaction target is F3. We used to search for range f..j which yielded {F2,F3}. However we now expand the range as soon as another file is added. In this case, when F2 is added, we expand the range to c..j and restart the search. That picks up file F1 as well. This change fixes a bug related to deleted keys showing up incorrectly after a compaction as described in Issue 44. (Sync with upstream @25072954)
