No igniters, just 'pad/drogue/landed' modes (where 'drogue' ==
'flying'). A constant 1Hz telemetry and RDF rate.

The flight code mashed together data processing, filtering and actual
flight managament into one giant pile. Split things up so that we
have:
ao_sample.c: Sensor data processing. Reads the ring, handles calibration
ao_kalman.c: Filter the data to track the accel/speed/height values
ao_flight.c: Flight state management, specific to rocketry.
The plan is to re-use ao_sample.c and ao_kalman.c for hardware not
specifically designed for rocketry, like TeleNano.

This generates the constants needed to implement Kalman filtering in

Eventually, telenano will run different code; prepare for this by
creating a telenano-specific main routine.

The TeleMini and TeleNano boards do not have either GPS or
accelermeters, and they also run the kalman filter which produces
standard unit measurements for the flight height/speed/accel
values. This makes the telemetry significantly
different. ao_telemetry_tiny.c sends the required data.
Note that TeleNano sends the same telemetry as telemini at this point;
there are a couple of values which are not useful, but the overhead of
sending them is small enough that the hassle of having three telemetry
formats seemed excessive.

This just uses the TeleMini bits, which should work fine for now.

This splits the logging code into management of the log space within
storage and separate code to actually write suitable log entries. A
new log writing module, ao_log_tiny, is added which writes only
altimeter data at a fairly low data rate for devices using on-chip
storage.

Require firmware to specify the end of its codespace in its Makefile,
and use this to determine where the start of available flash is. Should
give compile time errors if either there's no room left for storage, or
if there's not enough room for code.

The git version is built into ao_product.c and saved in eeprom log
files, providing useful diagnostics about the firmware revision used
for each flight. However, if ao_product.c isn't recompiled, then the
updated version won't be included. Force recompilation of this file
each time make is run to ensure that the final output contains an
updated version number.

The device serial number and radio calibration values are stored in
flash, mostly so that TeleDongle gets them saved.
Placing them in well-known locations (starting at 0xa0) makes it
possible to find the previous configuration and to re-write it
easily, without requiring the .map file.
altosui doesn't have the .map file parsing code, so it relies upon
this new technique. As a benefit, it reads the old values from the
device before reprogramming it.
