Refactor PI mutexes internal definitions
This patch adds the generic futex_lock_pi and futex_unlock_pi to wrap around the syscall machinery required to issue the syscall calls. It simplifies a bit the futex code required to implement PI mutexes. No function changes, checked on x86_64-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
