  Modified files:
    lib/libthr/thread    thr_private.h thr_spinlock.c 
  Log:
  Locking primitives and operations in libthr should use struct umtx,
  not spinlock_t. Spinlock_t and the associated functions and macros may
  require blocking signals in order for async-safe libc functions to behave
  appropriately in libthr. This is undesriable for libthr internal locking.
  So, this is the first step in completely separating libthr from libc's
  locking primitives.
  
  Three new macros should be used for internal libthr locking from now on:
  THR_LOCK, THR_TRYLOCK, THR_UNLOCK.
