Implement thread_delete function

[Patryk Kubiak]

The function thread_delete should be an simple interface, that will be available in the USER SPACE designed as part of POSIX modules for deleting thread.

Prototype for the function:

extern bool thread_delete( thread_t * Thread );

The function should use:

bool                     oC_Thread_Delete            ( oC_Thread_t * Thread );
