Replace "..." quoting with `...` quoting in output, to avoid slosh-escaping the
common double-quote character (") in log output.
Introduce alloca_str_toprint() function that produces an entire null-terminated
string in printable form.
Change various toprint strbuf helper functions to take two optional quote chars
instead of one mandatory.
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.
Replace DEBUG_SIMULATION with DEBUG_VOMP
Replace all printf(...) and fprintf(stderr,...) with WHYF(...) and DEBUGF(...)
Make all debug logging conditional on DEBUG_VOMP
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
