History
John Baldwin 6f88d2a870 Use thr_once() with once_t controls to initialize various thread_key_t 
objects used to provide per-thread storage in the RPC code.  Almost all
of these used double-checking with a dedicated mutex (tsd_lock) to do this
before.  However, that is not always safe with more relaxed memory orders.
There were also other bugs, such as one in __rpc_createrr() that caused a
new key to be allocated each time __rpc_createrr() was invoked.
