* `Lock`: trivial wrapper for FreeRTOS binary semaphores
* `LockGuard`: RAII wrapper for using `Lock`
* `printThreadInfo`: helper for showing which core/FreeRTOS task we are
running under
* Suppress warnings about conflicting library names in platformio.ini by
explicitly picking the libraries by id that we want.
* fix unused static function warning by making it not static ;)
* declare arduino-fsm as dependency for BluetoothOTA. Hopefully this
fixes the CI builds?
Tested: `pio run` builds.
