Kernel+LibPthread: pthread_create handles pthread_attr_t

Browse source 
Add an initial implementation of pthread attributes for:
  * detach state (joinable, detached)
  * schedule params (just priority)
  * guard page size (as skeleton) (requires kernel support maybe?)
  * stack size and user-provided stack location (4 or 8 MB only, must be aligned)

Add some tests too, to the thread test program.

Also, LibC: Move pthread declarations to sys/types.h, where they belong.
