Event mode: Enforce reliable hop limit and disallow default public MQTT (#4343)

Browse Source 
* 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
