History
David Xu 3f76af0f4a 1. use per-chain mutex instead of global mutex to reduce 
lock collision.
2. Fix two race conditions. One is between _umtx_unlock and signal,
   also a thread was marked TDF_UMTXWAKEUP by _umtx_unlock, it is
   possible a signal delivered to the thread will cause msleep
   returns EINTR, and the thread breaks out of loop, this causes
   umtx ownership is not transfered to the thread. Another is in
   _umtx_unlock itself, when the function sets the umtx to
   UMTX_UNOWNED state, a new thread can come in and lock the umtx,
   also the function tries to set contested bit flag, but it will
   fail. Although the function will wake a blocked thread, if that
   thread breaks out of loop by signal, no contested bit will be set.
