- Change LOCK_DEBUG so that it is always on if KTR is compiled in
regardless of the state of KTR_COMPILE. This means that we no longer
need to include sys/ktr.h before sys/lock.h to ensure a valid setting
for LOCK_DEBUG.
- Change the use of LOCK_DEBUG so that it is now always defined and its
value is used instead of merely its definition. That is, instead of
#ifdef LOCK_DEBUG, code should now use #if LOCK_DEBUG > 0.
- Use this latest to #error out in sys/mutex.h if sys/lock.h isn't
included before sys/mutex.h to ensure that the proper versions of the
mutex operations are used.
- As a result of (2) sys/mutex.h no longer includes sys/ktr.h in the
KERNEL case.
