This changes the full telemetry stream to include kalman data instead
of the old ad-hoc flight data. It's compatible in that the packet
sizes are the same so teledongle can receive either and figure out
which it has received.
A few plotting and testing tools are added to make validating the new
code easier.

Instead of using a delay between telemetry packets, use a telemetry
period and compute an appropriate delay each time. This requires
changing the ascent telemetry from a 50ms delay to a 100ms interval,
to provide a regular 10 packets-per-second rate. Before, we counted on
the telemetry packet taking about 50ms to send so that we would
receive about 10 per second.
This also eliminates delays during descent for RDF tones -- those will
get transmitted in the interval between telemetry packets without
interrupting the spacing of those packets.

Not all boards will have these, so fix places that use them to deal
with that.

What a terrible mistake! The flight computer serial numbers were
recorded in only 8 bits, so serial numbers > 255 would get truncated.
There's really no fix other than bumping the field to 16 bits and
reflashing every TM and TD on the planet. Very unfortunate.

Reports special tone along with the continuity checks.
Reports flight 0 in telemetry.

Instead of aborting the DMA and radio operation and expecting that to
be handled reasonably by the radio receiving task, rewrite things so
that the abort function just wakes the receiving task while that
terminates the DMA and cleans up the radio.
This eliminates all kinds of nasty bugs dealing with radio abort
smashing the radio registers at the wrong time, or interrupting a
radio transmission.

This makes it easier to tie the telemetry and eeprom files together as
they're now both labeled with serial and flight numbers, which should
be unique.

This allows the ground station to convert the accelerometer sensor
values into acceleration and speed data. This requires a new telemetry
data structure, and so TeleMetrum and TeleDongle units must be updated
synchronously. ao-view will parse either telemetry stream, and the
serial format from TeleDongle now has a version number to allow for
future changes.

It's pretty much impossible to RDF the rocket during flight, and it
interferes with the telemetry data stream. Leave it enabled on the pad
so that radios can be tested, and then re-enable it once the rocket
has landed.
This patch also turns the rdf 'on' time into a parameter so it can be
changed, and then sets that parameter to 500ms, once every 5 seconds.

Tracking the rocket on the ground may be easier using tones than using
the digital data stream, so we'll try that and see what we think.

SiRF message #4 includes signal strength and GPS engine state for each
of the satellites being tracked. This data is now parsed and sent to
eeprom and the radio.
