Build the hardware version string from the register definitions,
so I no longer forget to update it.
Check it at runtime against the build version registers.

Until we implement a proper reset of the microcontroller,
add a reset of the Cortex-M3 CPU core in system_reset() in order to
avoid getting stuck in a weird loop if we get a panic.

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).
