Title: replace separate roll and pitch gyro subsystems with an imu subsystem

I think it would be good to get rid of the old gyro.[ch] files and just make that into an (incomplete) IMU.

But several questions remain:

* how do we want to handle IMUs that don't have all sensors (e.g. not mag or accel at all, or only some gyros)
* what about the temperature compensation we had in gyro.c for the roll gyro only?
* Do we want/need that? Possibly for all gyros?
* Also use the ahrs_aligner to set the neutrals for these gyros at startup?
