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
