I've just checked in new versions of most files under
	sys/arch/sun3/

mostly to make everything compile with
	cc -Werror -Wall -Wstrict-prototypes ...

...also to get rid of __BROKEN_INDIRECT_CONFIG
in all the drivers used on the sun3.  Other changes:

Modified Files:
	machdep.c trap.c 
Log Message:
Make sure the MDP_STACKADJ flag is cleared in p->p_md.md_flags
Do this in both machdep.c:setregs() and trap.c:(end of syscall)
for now.  Need more analysis to see what is the best way...
Fixes PR#3034 (Thanks very much to Ian Dall for the fix!)

Modified Files:
	obio.c 
Log Message:
Add a diagnostic to panic when obio config data has a
default address, which is no longer supported on obio.
* Note that default addresses are pretty much useless on
  obio anyway, because the addresses never vary, and the
  code that supported them was just a waste.
