THRIFT ReadWriteMutex

Summary: Implemented a read/write lock class in thrift::concurrency

Reviewed By: marc

Test Plan: I compiled this, then compiled a version of fb303 that uses this
(future checkin pending further tests), then ran a binary using the new fb303
and it didn't crash as things were added to the map using the ReadWriteMutex

Revert Plan: yup

Notes: this should replace rw_lock.h for most clients
