* preflightSleep, notifySleep, notifyDeepSleep now allow arbitrary
drivers/devices/software to register for sleep notification.
* Use the proceeding to clean up MeshRadio - now the mesh radio is more
like an independent driver that doesn't care so much about other systems
* clean up MeshService so that it can work with zero MeshRadios added.
This is a prelude to supporting boards with multiple interfaces (wifi,
extra LORA radios etc) and allows development/testing in sim with a bare
ESP32 board
* Remove remaining ESP32 dependencies from the bare simulation target
this allows running on anything that implements the arduino API
because the ESP32 implementation will be different from NRF52
to make this possible I needed to decouple knowlege about bluetooth from
our mesh service. Instead mesh service now uses the Obserable pattern
to let any interested consumer get notified of important mesh changes
(currently that is only bluetooth, but really we should do the same
thing for decoupling the GUI 'app' from the mesh service)
@girtsf would you mind reviewing my Observer changes? I haven't written
C++ code in a long time ;-)
unique to each architecture. For now, we have "esp32" and "bare"
esp32 is the old esp stuff
bare is an target suitable for emulation that doesn't require any
particular hardware to run (no bluetooth, no i2c devices, no spi devices)
* to allow changing to new mesh transport
* to allow a different chipset for the radio
* to allow testing on hardware with a SimRadio
* new "bare" build env for a devboard with virtually no hardware
* make buttons optional
// We don't set useDisplay until setup() is called, because some boards have a declaration of this object but the device
// is never found when probing i2c and therefore we don't call setup and never want to do (invalid) accesses to this device.
Also - now that he fixed that, we can leave PMU interrupts on across sleep
Hopefully the following line will properly credit him in the magic github
universe...

* Break out debug screen to a separate class and make it thread-safe.
* Break out power state to a separate class.
* Show battery voltage, charging & USB status on debug screen.
* Show GPS lock / no lock
* Fix an off-by-one that I introduced earlier in `drawRows`.
Work towards separating out how Screen interacts with other stuff.
* `Screen` should now be thread-safe. All commands to it are put in a
queue and handled in `doTask` from the `loop()` task.
* Break dependency from `BluetoothUtil` to `Screen` by changing the
pairing request into a callback.
* All accesses to screen now happen through the class.
* Fix `drawRows` so that the text scrolls along with frame animations.
* Remove example code that wasn't used.
