pthread: Refactor semaphore code
The internal semaphore list code is moved to a specific file, sem_routine.c, and the internal usage is simplified to only two functions (one to insert a new semaphore and one to remove it from the internal list). There is no need to expose the internal locking, neither how the semaphore mapping is implemented. No functional or semantic change is expected, tested on x86_64-linux-gnu.
