1. Fix races in Windows pthread emulation

   The Windows mutex initialization code used InterlockedExchange to claim
   initialization.  A waiter could overwrite the initialized state with the
   initializing state, causing pthread_mutex_unlock to return without leaving
   the critical section and deadlock.
   Use compare-and-exchange to claim only an uninitialized mutex.  Use
   interlocked reads and publication for the mutex and once state so initialized
   objects are safely visible on ARM64.  Apply the mutex fix to the duplicate
   ECPG and libpq implementations.
