* Replaced the previous pthread_key implementation with a lockless one

that does not rely on the Be API TLS anymore, and is also more compliant
  with respect to the lifespan of the key specific values.
* It supports up to 256 different keys, which is equivalent of the solution
  that FreeBSD offers.
* The main thread now also gets a pthread_thread structure.
* Reenabled the POSIX suite test pthread_key_delete_2-1 as we now pass it.
* This also fixes bug #1642.
