kernel - Fix another hard critical section issue with syscons, revamp locking
* Use the new mtx_spinlock() facility instead of spinlock(). The new
facility supports reetrant locks.
* Call all sc_*() functions with the syscons lock held.
* Fix an issue in blink_screen() where a hard critical section panic
could potentially occur.
* Fix an issue in sc_puts() where adjusting the keyboard LED could still
cause a hard critical section panic. We just let the keyboard LED state
be wrong for now.
