* broker: declare and define per module
We no longer need to specify each Broker type in broker.h
But, we exchange that bit for explicit initialization of the instance
Define helper macros to generate boilerplate code
- namespace with Instance, Register(), Publish()
- forward Register(...) -> Instance.Register(...),
Publish(...) -> Instance.Publish(...)
* don't check for broker when deps enable it
- general conversion from .ino modules into a separate .cpp files
- clean-up internal headers, place libraries into .h. guard .cpp with _SUPPORT flags
- fix some instances of shared variables instead of public methods
- tweak build system to still build a single source file via os environment variable ESPURNA_BUILD_SINGLE_SOURCE
- use similar to relay & wifi, configuration through helper methods that
use indexed defines
- clock cycles for led delay polling
- button mode defaults
