Cleanup the LinuxKPI mutex wrappers.Add support for using mutexes during KDB and shutdown. This is alsorequired for doing mode-switching during panic for drm-next.Add new mutex functions mutex_init_witness() and mutex_destroy()allowing LinuxKPI mutexes to be tracked by witness.Declare mutex_is_locked() and mutex_is_owned() like inline functionsto get cleaner warnings. These functions are used inside WARN_ON()statements which might look a bit odd if these functions get fullyexpanded.Give mutexes better debug names through the mutex_name() macro whenWITNESS_ALL is defined. The mutex_name() macro can prefix parts of thefilename and line number before the mutex name.MFC after: 1 weekSponsored by: Mellanox Technologies List of files: /freebsd/sys/compat/linuxkpi/common/include/linux/mutex.h
