a9ccd38adc Improve overlay buffer ob_xxx() primitives 
All ob_append_xxx(b,...) functions return void

ob_makespace() returns 1 if successful, 0 if not

Add ob_overrun(b) predicate to check for overrun after any number of
appends

a95ef79139 Use sid_t everywhere 
Remove stowSid() at last

Change API of tohex() and strbuf_tohex(), to pass string length instead of
binary byte count.  This allows odd numbers of hex digits to be produced.

Remove alloca_tohex_sid(); replace with alloca_tohex_sid_t()

New alloca_tohex_sid_t_trunc() macro

8771a50b14 Fix TTL out-of-range bug 
Was causing two routing tests to fail since the TTL decrement
logic was fixed in a8b88a46

The default TTL of 64 overflowed the 5-bit unsigned int in the MDP
packet header

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.

66e0711d6b Only send one audio block per packet, but request that it be sent multiple times 
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

bba6839656 Initial stab at porting to Solaris. 
It compiles without warning (with CC=gcc) but doesn't link
because NaCL doesn't build yet.

f37ec5af09 Reduce use of stderr in many places 
serval_packetvisualise() is now replaced by DEBUG_packet_visualise() which uses
logging system not stderr (so now it will appear in Android log).

Replaced several fprintf(stderr,...) with DEBUGF(...).

Command line only prints a full help message on "help" command -- a command
parse failure simply informs the user about the "help" command.
