* Add FY805 protocol
* Fix stray space
* Fix multi sending 120% instead of 100%.
* Implement a custom telemetry for the multi module
The custom telemetry allows the module to tell the telemetry protocol to OpenTX and also allows signaling the status of the Module (e.g. invalid protocol) to OpenTX
This should also close#3979.
* Cosmetics and a few small bugfixes
* remove empty if
* Move status line directly below the mode to be always visible when selecting a protocol
* warn if internal RF module is on
* Replace sprint with small helper function to build on AVR ARM (AR9X, 9XPRO, …)
* TR in wrong order, RF_PROTO_OFF inverted
* Refactor definition of Multimodule protocols to have one central place to define all multi protocol properties
* Also update protocols in companion
* Update multi version number to display as a.b.c.d
* Various fixes for gtests that were shown when running tests in random sequence. Enabled random gtests shuffling in commit tests.
* 9X gtests fixes
* more gtests fixes
* even more gtests fixes
* Another round of gtests fixes
* Code deduplication with test fixtures
* More fixtures
* Rename EXT option to TELEMETRY
* Change test accordingly
* Rename FRSKY to TELEMETRY_FRSKY
* Rename ARDUPILOT to TELEMETRY_ARDUPILOT
* More renames (JETI, MAVLINK, NMEA)
* Fixes to make commit-test happy
* Further tests added to commit-test
* Cleanup
* Rename EXTSTD to TELEMETRY_NONE
