Basic route aggregation Add a new protocol offering route aggregation. User can specify list of route attributes in the configuration file and run route aggregation on the export side of the pipe protocol. Routes are sorted and for every group of equivalent routes new route is created and exported to the routing table. It is also possible to specify filter which will run for every route before aggregation. Furthermore, it will be possible to set attributes of new routes according to attributes of the aggregated routes. This is a work in progress. Original work by Igor Putovny, subsequent cleanups and finalization by Maria Matejka. This is a split-commit of the neighboring aggregator branch with a bit improved lvalue handling, to have easier merge into v3.
