589c334d5b Fakeradio responds to mavlink heartbeat packets 
- attempts to send mavlink packets in one piece

6f26594447 Simplify mavlink link frame creation 
- build one frame at a time directly from the prepared overlay buffer

e29564bc6c Refactor fakeradio 
- completely event driven and non-blocking
- modelling of tx & rx serial buffers that will truncate on overfilling
- each radio takes turns to send a packet, with approx TDMA overhead

3b1ae5cbb0 Env vars SERVAL_KEYRING_PATH and SERVAL_KEYRING_READONLY 
To support release signing operations without having to copy the release
keyring from its USB stick (into an instance directory), and reducing

options.

Also remove some unused code.
