    htl: Make pthread_[gs]etspecific not check for key validity

    Since __pthread_key_create might be concurrently reallocating the
    __pthread_key_destructors array, it's not safe to access it without the
    mutex held. Posix explicitly says we are allowed to prefer performance
    over error detection.

    htl: Fix initializing the key lock

    The static pthread_once_t in the pt-key.h header was creating one
    pthread_once_t per includer.  We have to use a shared common
    pthread_once_t instead.

    htl: Destroy thread-specific data before releasing joins

    Applications may want to assume that after pthread_join() returns, all
    thread-specific data has been released.
