Implement Route Multiplexer

[jdknives]

Feature description

Currently applications can make use of only one route to a remote. Applications such as the VPN would benefit quite heavily from a route multiplexing module that allows to open and use multiple routes in case of

• congestion on a route

• a route drops

This way, a VPN could create multiple routes upon startup and switch from one to the next one in case a route breaks down smoothly without an interruption.

Possible implementation

The route multiplexer should request 3 routes and always have two routes as backup. Upon failure of one route, the multiplexer should switch to the next route.
