* chopstx.c (AIRCR): New.
(chx_init): Setting for PRIGROUP 2-bit:2-bit.
(sched): Unlock cpu_sched_lock on return to thread.
(preempt, chx_timer_expired, chx_handle_intr): Those can be
considered holding cpu_sched_lock (by its equal exception
priorities), thus no acquiring lock required.

* chopstx.c (chx_spin_lock, chx_spin_unlock): Rename.
