kernel -- lockmgr debugging.
* Track exclusive lockmgr locks held by a thread in a per-td stack,
td->td_lockmgr_stack[]. The stack also tracks the depth of the lockmgr
recursion, if any.
* Move td->td_locks count from SIMPLELOCK_DEBUG to DEBUG_LOCKS; we have not
used a simplelock to interlock lockmgr lock updates in a very long time.
