sd_journal_send() implicitly add fields for the source file,
function name and code line from where it's invoked. As code
location fields CODE_FILE, CODE_LINE and CODE_FUNC are handled
by PA's log module, we do not want the automatic values
supplied by the sd_journal API.
Without suppressing these, both the actual log event source
and the call to sd_journal_send() will be logged:
$ journalctl -b -f -o json-pretty
[...]
CODE_FILE : [ pulsecore/log.c, pulsecore/module.c ],
CODE_LINE : [ 505, 181 ],
MESSAGE : Failed to load module module-gconf
CODE_FUNC : [ pa_log_levelv_meta, pa_module_load ],
[...]
