Tuning pthread_key_t type

Both FreeBSD and DragonFly define pthread_key_t as int, while Linux
defines it as uint. As pthread_key_t is used as an opaque type and
storage size of both int and uint are the same, this is rather a
cosmetic change.

iOS uses ulong (as OS X) so difference is critical on 64bit platforms.
