* src/threads/native/threads.c (allocLockRecordPool): Relink the free list

* src/threads/native/threads.c (allocLockRecordPool): Relink the free list
of lock records when reusing a pool from the global_pool. This avoids
cross-linking of lock record owned by different threads, and hopefully
fixes our long-standing deadlock problem.

* src/threads/native/threads.c (allocLockRecordSimple, recycleLockRecord)
(initObjectLock): Temporarily added assertions to shake out possible
further bugs in the free list handling.

* src/threads/native/threads.c (monitorEnter, monitorExit): Commented.

* src/threads/native/threads.c (Changes): Added my name to 'Changes'.

* src/threads/native/threads.c (vim boilerplate): Added.
