Add stricter asserts to DIAGNOSTIC kernels to help catch mutex and
rwlock misuse. In particular, this commit makes the following
changes:
1. i386 and amd64 now count the number of active mutexes so that
assertwaitok(9) can detect attempts to sleep while holding a mutex.
2. i386 and amd64 check that we actually hold mutexes when passed to
mtx_leave().
3. Calls to rw_exit*() now call rw_assert_{rd,wr}lock() as
appropriate.
