I've checked these changes into the thread_dev branch (rw_lock.hpp,
rw_mutex.hpp, rw_mutex.cpp). Anyone who is interested please take a
look and comment.

Major changes (see change logs in the files themselves for additional
details):

* Add lock promotion and demotion.
* Rename to improve consistency and eliminate abbreviations:
     Use "read" and "write" instead of "shared" and "exclusive".
     Change "rd" to "read", "wr" to "write", "rw" to "read_write".
* Change try lock & timed lock constructor parameters for consistency.
* Add many assertions to test validity of mutex state and operations.

Things still to be done (any help with these tasks would be greatly
appreciated):

Update documentation
Update tests
