Update MIPS stack backtrace code to trace through locore functions,
...
traps, and interrupts The earlier (4.4bsd) code didn't do the first two, and
got the last one wrong. Also print some functions (e.g., trap handlers)
by name. Add hook to use something other than printf() as the output
function, e.g,. for kernel debugging.
Tested with the `native' toolset, but not ELF format kernels.
(i.e., unwinding the $GP register is not tested.)
The stack backtrace code that interprets and unwinds stackframes is still
opaque and stylistically awkward.

Add prototype (new-style) config for pmax. This doesn't yet work;

auto-configuration initialization code is missing. It uses "needs-count"
flags to come slightly close to what the old-style pmax source expects.
Perhaps autoconfig code can be lifted from the alpha port or volunteers
found to write some.
