4450116472 Refactor string functions, add str_fromprint() 
Move lots of non-Serval-specific string functions from "serval.h"/dataformats.c
to "str.h"/str.c.

Add str_fromprint() function that reverses the effect of toprint(): interprets
escape sequences in the source string "\n\t\r\0\xHH\\" and replaces them with a
single char in the destination string.

bf9f8559f1 Various debug fiddles and conversion from select() to poll()

There is still a bug in dequeuing packets though it seems.

144f3ee4b1 Thinned out debug messages and fixed SID generation bug to make sure 
that it always generates a valid SID, i.e., not beginning with 0.

b6ce25ab24 Believe I have found and stemmed the memory corruption bug, although

cbb1939241 Fixed various compiler warnings. 
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.

b075b51c43 Merged overlay_payload and overlay_frame structures to just overlay_frame 
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.

62a7a65fd6 More work on parsing overlay frames. Now has bare bones to think about 
forwarding frames. routing is still not implemented, so it doesn't do anything yet,
but it does try.

bd16fbbf5b Address lookup from cache works :)

cf778e1efd Various further work on overlay mesh.

229850c8d7 Overlay mode with address summarisation closer to working. 
Self-announcements now abbreviate addresses, and in theory they
get expanded on reception -- but more testing and coding required.
