Log Message:
- Add cleaner supports for model specific sub-milliseconds high resolution
timer circuit.  3MAX+ has IOASIC bus cycle counter and MAXINE has its own
circuit.  R4000 3MIN ultilizes onchip counter (but I'm not sure how
acculately current codes measure on runtime).
- Add write buffer flush routines for each model.  Most DECstations have
their own logics for write buffer flushing different from each other.
It's not good to assume R3000 computers have write buffer drain logic
tied with processor's CU0 bits.  Some of modern R3000 CPUs have write
buffer 4 deep FIFO circuit builtin.
- A bit cleanup in conf/files.pmax.
- Add missing kn02ba_memerr() call in pmax/dec_3min.c
- Nuke old remainings in include/autoconf.h
