494a766b9e Improve str.h and str.c 
Move alloca_tohex() from serval.h into str.h so it can be used stand-alone.

Rename str_to_ll_scaled() to str_to_int64_scaled().  Add str_to_uint64_scaled()
and scale_factor().

Add a few more URI parsing functions.  Move some functions out of str.c and
into str.h as inline functions.

27a0a6eeb5 Introduce struct __sourceloc 
Replaces (const char *file, unsigned int line, const char *function) arguments
to all logging functions, simplifies malloc/free tracking code in
overlay_buffer.c and Rhizome manifest alloc/free tracking in rhizome_bundle.c.

Use __HERE__ macro instead of (__FILE__, __LINE__, __FUNCTION__) everywhere.

Special __NOWHERE__ macro is equivalent to (NULL, 0, NULL).

Declare net.c functions in new "net.h" header, so log.c doesn't have to pull
in the entire "serval.h" just to use write_str().

Facilitates progress on issue #2.

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.

d11258cefc Overhaul debug flags 
Config debug flags are now represented as individual items, eg:
   servald config set debug.verbose yes
   servald config set debug.rhizome yes
instead of aggregated, eg:
   servald config set debug verbose,rhizome  <-- no longer works

Added a debug flag "debug.all" that can be set and cleared, over which
individual flag sets/clears take priority.

Slimmed down dna.c by moving some globals and functions to the files where they
are used.

Default command line (help message) is now the new style, not the deprecated
style.

requires ROOT on android).

c7dd475d50 Further work on MDP, including dispatching low-priority data when 
it can fit in frames.  A nasty bug in queue code needs fixing.
Also, we only send tick frames at present, and need to add code
for dispatching packets at other times (bandwidth allowance permitting).
So the whole bandwidth management code needs to get finished.

70497df7b5 More work on MDP. Removed some debug fluff. 
Added framework for MDP ping, and some work towards MDP port binding
and sending packets with option to wait for reply.  MDP server
doesn't yet support port binding, and client doesn't yet support
reading replies.
