The pmax 3100 interrupt-init code is broken: cpu_startup() enables
...
interrupts before it calls configure(). On 3100s, this can result in
the ethernet interface interrupting before leprobe() is ever called.
Be a bit more defensive in leintr(), where it was dereferencing a null
pointer. This reputedly fixes the oft-reported problems of 3100s not
ooting unless they're on an idle net or had a hard reset done before boot.
(Reworking the config code completely would be nice too.)

If we panic inside trap(), Do a stack traceback before printing the trap log.
...
Also change the stack-traceback code to avoid having multiple returns
(and thus multiple stack pops) because with gcc -O2 that breaks the
heuristic that a "jr ra" preceding the PC precedes code to push the
current stack frame. Which breaks stacktrace() before it even
traces past itself :-(. Use a goto instead.

make this work sanely on a 64-bit machine. Sacrifices a small bit of

error checking in the DIAGNOSTIC case. These changes might be backed out,
if it's decided that MINBUCKET should be 5 (rather than 4) on the alpha.
However, doing that has its own set of nasty consequences.

changes by me:

* Make the debugging code more robust and complete.
* Tweak the output routine for better performance, and to eliminate an ugly
kluge.
Various other style cleanup. Needs more work.
