core remains a bad name to use -- dirvish skips files (and
directories, it seems) with that name.

Only present when HAS_FLIGHT_DEBUG is enabled, this command lets the
user check the orientation tracking code by showing the current
orientation and when the calibration values are reset.

Trying to compute the combined rotation by taking the x/y/z rotations
as a vector is a good approximation, but not accurate enough for our
application given the large angles we sometimes see.
Instead, use a correct-but-expensive function with a pile of
transcendental function calls. The STM32L seems to be fast enough at least...

This initializes the rotation with the angle from vertical, rather
than simply recording the off-angle vector. Doing this allows us to
accurately track the true orientation of the rocket, instead of just
the offset from the initial non-vertical orientation.

This reduces the offset error by a bit, minimizing gyro drift.

Average the IMU accelerometer values pointing up and down so that we
have a zero-g offset for all three axes. This can then be used to
compute which direction the rocket is pointing while sitting on the pad.

This tracks the angle-from-vertical as an additional input to the pyro
channels.

This gets the long-term averages for the 6dof sensors recorded into
the first flight log record.

Having long-term ground averages recorded to the eeprom file will make
post-flight analysis of the data better.

These just shuffle the various definitions of data macros around to
make the include files more sensible looking.

Average data for 5 seconds, wait 5 seconds and if still in pad mode,
replace the existing data with the new data. This should avoid
averaging in boost data while still keeping things reasonably current.

Was just a temporary hack to keep cc1111 products building during MM development.

They use a different code path for accel as they don't have the
VCC compensation code in place.

Split out sources into separate directories:
core: architecture and product independent bits
cc1111: cc1111-specific code
drivers: architecture independent drivers
product: product-specific sources and Makefile fragments
util: scripts for building stuff
This should have no effect on the built products, but testing is encouraged
