Timer code rework. Done so far:
o Fix interrupt handler to not loose cycles
o Warn about lost interrupts.
o Fix calibration of the R4000 CPU timer.
Still to do:
o General cleanup of the timer code
o Microsecond timers for the Indy
o The calculated values for r4k_offset are still off by ~480 from the
theoretical values. That means we're going to loose about 46 s per
day. Are the crystals that bad or is there still a bug hidden
somewhere? Maybe an option to set r4k_offset to a user supplied
value might help?
o Handle lost interrupts more gently so we don't loose time.
o Handle 100MHz R4000 count / compare bug.
