noxiouz 329233dcbf sd-journal: make sd_journal_get_data() output params optional
Allow callers to pass NULL for ret_data and/or ret_size when they only
need to check whether a field exists.  Initialize provided output
pointers to safe defaults and update the manual page accordingly.

Propagate the NULL-ness through to journal_file_data_payload() so that
downstream helpers can optimize for the existence-check case.
