Add a new 'show lock' command to ddb.  If the argument has a valid lock
class, then it displays various information about the lock and calls a
new function pointer in lock_class (lc_ddb_show) to dump class-specific
information about the lock as well (such as the owner of a mutex or
xlock'ed sx lock).  This is easier than staring at hex dumps of locks to
figure out who owns the lock, etc.  Note that extending lock_class doesn't
affect the ABI for any kernel modules as the only code that deals with
lock_class structures directly is kern_mutex.c, kern_sx.c, and witness.
