sm1000_main: First stab at a time-out timer.
...
This needs calibration, but basically it cuts transmission after a fixed
period, giving warning beeps in the time just prior to timeout.
For now it is disabled by default, and the timing for now is way off.

This allocates a few sectors of flash for the following purposes:
- Sector 0: ISR vector data. (This gets mapped to address 0; so we have
no choice, the ISR data *must* reside here.)
- Sector 1..3: Virtual EEPROM. We'll stash our configuration parameters
here. We have 48kB available.
- Sector 4.. onwards: Program data
