* Re #3815: Disk cache: Write statistic added. Bigger disk cache. Show disk cache misses in CLI.
* Update to the latest FatFS R0.12b (all existing OpenTX patches have been already applied in upstream, only few ff.h modifications needed for simulator)
* Missing file
* SD card manager: do not show parent dir [..] for root directory
* Change default at model creation from XJT-D16 8CH to XJT-D16 16CH on Taranis and Horus
* Set defaultto 16CH also on protocol change
* External module on Taranis
* MACRO's are good for you
* They are so good they should be used everywhere !
* And everywhere also includes the 9X UIs!
* Re #3827: added mutex to getADC(), because adcRead() is not reentrant
* Re #3827: alternative solution to prevent calling getADC() from different threads, because adcRead() is not reentrant
* Cosmetics
* * Switches audio filenames were wrong [Horus]
* sdAvailableLogicalSwitchAudioFiles was too small (we now have 64 LSW), fixed with BitFiled class
* Enabled Travis Gtests on Horus
* SD card version mismatch trace
* Re #3815: Audio debug timers added
* 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
* Radio init / masstorage start / massstorage end / shutdown sequences reordering:
- More traces
- Fixes#3642
- Reuses idea of #3662
Still not finished and completely untested
* More traces
* Compilation fix
* Reuses the idea of #3652
* Alarms were checked 2 times on massstorage end
- keys beep and haptic refactoring (not anymore audio events)
- trims move/mid/min/max refactoring (trim end splitted to trim min / trim max)
- S6R new alarms
- S6R servos/rx status displayed as a text (not an integer which has no sense)
- Timer countdown configuration
- The splash was not displayed (but the timeout was there) after the first calibration
* Only clear sensor.persistentValue when the sensor.persistent is disabled and not on every shutdown.
* Only show persistent option for calculated type sensors (only these actually get saved in EEPROM)
* Fixes#3432: radio option added to turn on/off ADC jitter filter (ported from master)
* Gtests fix
* Re #3432: compilation fix
* Re #3432: existing field split to accommodate the new option without the RadioData size change
