- Remove <machine/mutex.h>.  Most of the headers were empty, and the
  contents of the ones that were not empty were stale and unused.
- Now that <machine/mutex.h> no longer exists, there is no need to allow it
  to override various helper macros in <sys/mutex.h>.
- Rename various helper macros for low-level operations on mutexes to live
  in the _mtx_* or __mtx_* namespaces.  While here, change the names to more
  closely match the real API functions they are backing.
- Drop support for including <sys/mutex.h> in assembly source files.
