changes since two days ago:
...
drop , address=0xf0000 from romimage line.
newer bochs has a 128k bios that it loads elsewhere.
so let bochs decide where the romimage goes.
change cpu quantum to 1 (default is 5, max is 16)
in an attempt to provoke more races. only provokes
them slightly more frequently, may not be worth
the slowdown.

believe it or not, this was working
...
the macro expansion of "char *cp;" turned into
char *(curproc[cpu()]); which declares a dynamically
sized array of char* called curproc.
so then &cp == &(curproc[cpu()]) was actually a
stack variable as "expected". it was one past the
end of the array, but the implicit alloca allocated
more than was necessary.
do not tell me that making cp a #define was a bad idea.
there are worse problems to fix. more on that later.

Apparently the initial interrupt count lapic[TICR]
...
must be set *after* initializing the lapic[TIMER] vector.
Doing this, we now get clock interrupts on cpu 1.
(No idea why we always got them on cpu 0.)
Don't write to TCCR - it is read-only.
