History
Attilio Rao 90356491d7 - Embed the recursion counter for any locking primitive directly in the 
lock_object, using an unified field called lo_data.
- Replace lo_type usage with the w_name usage and at init time pass the
  lock "type" directly to witness_init() from the parent lock init
  function.  Handle delayed initialization before than
  witness_initialize() is called through the witness_pendhelp structure.
- Axe out LO_ENROLLPEND as it is not really needed.  The case where the
  mutex init delayed wants to be destroyed can't happen because
  witness_destroy() checks for witness_cold and panic in case.
- In enroll(), if we cannot allocate a new object from the freelist,
  notify that to userspace through a printf().
- Modify the depart function in order to return nothing as in the current
  CVS version it always returns true and adjust callers accordingly.
- Fix the witness_addgraph() argument name prototype.
- Remove unuseful code from itismychild().

This commit leads to a shrinked struct lock_object and so smaller locks,
in particular on amd64 where 2 uintptr_t (16 bytes per-primitive) are
gained.
