* Event mode: Enforce reliable hop limit
* Event mode: Short circuit wantsLink on MQTT for default broker address
* Just enforce at channels level since everything uses this
* For events never forward packets with excessive hop_limit
* In EVENT_MODE, don't respond with hop_limit set more then the configured max.
* Correct hop_start when correcting hop_limit in event mode.
* Make EVENT_MODE work from userPrefs.h
* Event mode: Disallow Router or Repeater roles
