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.

259b9a9d24 Logging/debug improvements: __WHENCE__, __whence

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.
