Modified Files:
	syssrc/sys/arch/m68k/include: lock.h

Log Message:
On the m68k, the most efficient type for __cpu_simple_lock_t is
an unsigned char, since that is what the `tas' instruction uses.

While I'm here, implement the __cpu_simple_lock family of routines.
Why?  One, because they're easy.  Two, so Steve can get master/slave
MVME systems talking across the backplane.  :-)
