This also introduces a hasher for js::Thread::Id which could certainly use a
good double checking. I wasn't totally sure which parts of the Id are actually
unique and/or belong in the hash.

Please remove |rekey|. It should not be instantiated unless you try to actually use rekeying and we *really* want the compile to fail if you think you need to change a Thread's id.

|ptThread| is a pthread_t, so you'll need an & in front of it to call HashBytes.
