Added proper check to suppress frames claiming to come from
ourselves ( necessary for squelching multi-hop broadcasts, although
we need an extra step there of having transaction ids on broadcast
frames so that we can flood smartly).
Change overlay_frame payload to use an overlay_buffer structure for
consistency and ease of payload construction.
Added some sanity checking to peer score calculation.
Getting closer to being able to TX acks to selfannouncements.
Other little things to accomplish these.
which is now used for both encapsulation and decapsulation.
Improved payload length encoding scheme to be shorter for most payload
lengths.
selfannouncement frames now get directed to stub functions for
implementation.
Still doesn't know about broadcast properly or a pile of other things, oh, and
the frames are completely empty, but none the less, we are now sending frames.
Fixed Linux assumptions.
Added parsing of overlay mesh interface specification from command line.
Separated overlay mesh code out into several files.
Overlay mesh is still far from working, but the infrastructure is coming together.
