reliable messaging tasks (stage one for DSR):
- add a 'messagePeek' hook for all messages that pass through our node.
- use the same 'recentmessages' array used for broadcast msgs to detect duplicate retransmitted messages.
- keep possible retries in the list with rebroadcast messages?
- DONE use the same 'recentmessages' array used for broadcast msgs to detect duplicate retransmitted messages.
- keep possible retries in the list with to be rebroadcast messages?
- for each message keep a count of # retries (max of three)
- delay some random time for each retry (large enough to allow for acks to come in)
- once an ack comes in, remove the packet from the retry list and deliver the ack to the original sender
- after three retries, deliver a no-ack packet to the original sender (i.e. the phone app or mesh router service)
- add a max hops parameter, use it for broadcast as well (0 means adjacent only, 1 is one forward etc...). Store as two bits in the header.
