Peter Portante 992149c07e Periodically call sd_journal_process in journalctl 
If `journalctl` take a long time to process messages, and during that
time journal file rotation occurs, a `journalctl` client will keep
those rotated files open until it calls `sd_journal_process()`, which
typically happens as a result of calling `sd_journal_wait()` below in
the "following" case.  By periodically calling `sd_journal_process()`
during the processing loop we shrink the window of time a client
instance has open file descriptors for rotated (deleted) journal
files.

**Warning**

This change does not appear to solve the case of a "paused" output
stream. If somebody is using `journalctl | less` and pauses the
output, then without a background thread periodically listening for
inotify delete events and cleaning up, journal logs will eventually
stop flowing in cases where a journal client with enough open files
causes the "free" disk space threshold to be crossed.
