Created a private simple_lock to control accesses to com data structs
and hardware.
There is now another simple_lock around clock data/hardware accesses in
clock.c and microtime.s.  It is my belief that this is the only area
sio/cy might stumble into during an unblocked INTerrupt.  Thus I separated
the sio/cy code from the generic disable_intr()/enable_intr() routines.

Controlled by smptests.h: USE_COMLOCK, ON by default.
