Add test case for new feature of the "rhizome add" command: if the author SID
is not specified (empty arg) then it searches the keyring for the author.
Removed "authorSid" argument from several functions that also take a struct
rhizome_manifest * arg, since the author, if known, is now supplied in the
struct.
Improve return value handling and refactored some rhizome crypto code.
If we receive a large buffer of audio, we want to stuff the packet with multiple frames and send them together.
And we want to send redundant copies of the audio to help recover from packet loss.
But if all our redundant copies end up in the same packet, we're screwed anyway.
This is a temporary hack until the network layer implements NACK / retry for resilient multi-hop delivery
Move DEBUG_ and LOG_LEVEL_ macro constants from constants.h into log.h.
Move dumpResponses() out of log.c, so that log.h is almost ready for re-use
(still depends on conf.h).
Remove unused and now obsolete catv() function -- replaced with toprint()
and alloca_toprint().
Add copyright/licence comments, fix up some copyright attributions.
Add #ifndef..#define..#endif __SERVALD_FOO_H to header files: log.h serval.h
constants.h
