We were losing timer events because usecs_to_ticks(deadline) was
clipping the value when deadline was larger than 0x08888888 (deadline is
a timestamp rather than a delay).
The computation of the timer deadline has been modified to avoid the
clipping issue.

This is fairly large change set to accomodate a new hardware
release. There are enough differences to require refactoring the
registers.h file. Autogenerated constants are now in gc_regdefs.h
and all constant names begin with GC_, while register names are
defined in registers.h and begin with GR_.
Yes, I know the new header files are wider than 80 chars, but we
agreed that was okay in some cases if it makes them more readable
(see commit 3500c28).

Run the "gettime" and "timerinfo" and "taskinfo" and "waitms"
commands. Compare the elapsed time with the real world. They seem
to match.
