      system: fmtlib logger implementation · e08cbed3
      Henri Chataing authored 
      - The fmtlib logger is implemented in <bluetooth/log.h>.
  The header defines the following templated logs function:

    template<typename T...>
    log::fatal(fmt::format_string<T...> fmt, T...args);
    log::error(..);
    log::warn(..);
    log::info(..);
    log::debug(..);
    log::verbose(..);

- Front-end, logs are printed out by invoking these
  macros with the macro LOG_TAG defined _before_ the
  inclusion of #include <bluetooth/log.h>

- Back-end, a single method must be implemented for all supported
  platforms (android, floss, host):

  namespace log_internal {
  void vlog(Level level, char const *tag, char const *file_name, int line,
            fmt::string_view fmt, fmt::format_args vargs);
  }

- Default implementations are provided:
  + vlog_android: outputs to <log/log.h> __android_log_write_log_message
  + vlog_syslog: outputs to <syslog.h> syslog
