        src/lib/libpthread: Makefile TODO pthread.c pthread_int.h
            pthread_misc.c pthread_mutex2.c pthread_rwlock2.c
        src/lib/libpthread/arch/i386: _context_u.S pthread_md.c pthread_md.h
        src/lib/libpthread/arch/x86_64: _context_u.S pthread_md.h

Log Message:
Mutexes:

- Play scrooge again and chop more cycles off acquire/release.
- Spin while the lock holder is running on another CPU (adaptive mutexes).
- Do non-atomic release.

Threadreg:

- Add the necessary hooks to use a thread register.
- Add the code for i386, using %gs.
- Leave i386 code disabled until xen and COMPAT_NETBSD32 have the changes.
