Add support for lockdep.
lockdep is a valgrind skin which performs pthread locking correctness
validation. In particular it allows one to write assert(HOLDS_LOCK(mutex))
which both documents the preconditions for a function and enforces them
when the program is run under lockdep.
As an aide to lockdep (as it works by intercepting the pthread functions),
all the mutexes should be initialised and destroyed using
pthread_mutex_init() and pthread_mutex_destroy() rather than using static
initializers and no-ops.
