introduce logging api and convert all library output to use it
- multiple debug context calls lwsl_ err, warn, debug, parser, ext, client
- api added to set which contexts output to stderr using a bitfield log_level
- --disable-debug on configure removes all code that is not err or warn severity
- err and warn contexts always output to stderr unless disabled by log_level
- err and warn enabled by default in log_level
