pvti: Packet Vector Tunnel Interface

This plugin implements a PoC of UDP-based tunnel substrate whose aim is
to specifically provide higher MTU to the upper layers by chunking
the payload PDUs into smaller packets with full 5-tuple.

At the same time, if there are multiple small packets to
the same destination during the vector processing, they
are packed into "carrier" packets up to underlay MTU size.

It does assume a trustworthy underlying medium, thus for the
operation over Internet it requires the use of encryption layer
underneath.
