Update of /cvsroot/src/sys/arch/hp300/hp300
In directory netbsd1:/var/slash-tmp/cvs-serv21417

Modified Files:
	trap.c 
Log Message:
Handle kernel trace traps and breakpoints like the Sun3 port:
	- Only pass user trace traps and breakpoints on to trap().
	  Gets rid of some hair in the trace/breakpoint trap cases.
	- Before entering the debugger, switch to a temporary
	  stack so that the debugger can alter the stack pointer.
	- Add glue for KGDB (still not complete).
Some other minor cleanup:
	- Protect against some bad pointer derefs.
	- Be more a little more verbose when a fatal trap
	  occurs to aid debugging.
