Fix kernel-doc notation in linux/mutex.h and kernel/mutex.c,
then add these 2 files to the kernel-locking docbook as the
Mutex API reference chapter.

Add one API function to mutex-design.txt and correct a typo in
that file.

Chapter 6 is right about mutex_trylock, but chapter 10 wasn't.  This error
was introduced during semaphore-to-mutex conversion of the Unreliable
guide.  :-)

If user context which performs mutex_lock() or mutex_trylock() is
preempted by interrupt context which performs mutex_trylock() on the same
mutex instance, a deadlock occurs.  This is because these functions do not
disable local IRQs when they operate on mutex->wait_lock.

Since the consensus seems to be to eliminate semaphores where possible,
we shouldn't be educating people about how to use them as locks.  Use
mutexes instead.  Semaphores should be described in a separate document
if we end up keeping them.
