Best-effort multihop forwarding

The rmh module implements a multihop forwarding mechanism.

Routes must have already been setup with the route_add() function. Setting up routes is done with another Rime module such as the route-discovery module.

The hop-by-hop reliable multi-hop unciast primitive is similar to the best-effot multi-hop unicast primitive except that it uses the reliable single-hop primitive for the communication between two single-hop neighbors.

Channels

The rmh module uses 1 channel.
