History
John Baldwin 2d96f0b145 - Move state about lock objects out of struct lock_object and into a new 
struct lock_instance that is stored in the per-process and per-CPU lock
  lists.  Previously, the lock lists just kept a pointer to each lock held.
  That pointer is now replaced by a lock instance which contains a pointer
  to the lock object, the file and line of the last acquisition of a lock,
  and various flags about a lock including its recursion count.
- If we sleep while holding a sleepable lock, then mark that lock instance
  as having slept and ignore any lock order violations that occur while
  acquiring Giant when we wake up with slept locks.  This is ok because of
  Giant's special nature.
- Allow witness to differentiate between shared and exclusive locks and
  unlocks of a lock.  Witness will now detect the case when a lock is
  acquired first in one mode and then in another.  Mutexes are always
  locked and unlocked exclusively.  Witness will also now detect the case
  where a process attempts to unlock a shared lock while holding an
  exclusive lock and vice versa.
- Fix a bug in the lock list implementation where we used the wrong
  constant to detect the case where a lock list entry was full.
