PTP device symlink creation rules are currently executed only when the
udev action is 'add'. If a user reloads the rules and runs the udevadm
trigger command to reapply changes, the symlink may be deleted, which
can prevent the chronyd service from restarting properly.

This fixes the following issues:
- We have a journal file, which contains entries of boot A and B. Let T
be the timestamp of the _last_ entry of boot A.
If sd_journal_seek_monotonic_usec() is called for boot A with a timestamp
_after_ T, following sd_journal_next() will provide the _first_ entry of
boot A, rather than the first entry of boot B.
- We have two journal files X and Y. The file X contains entries of boot A.
Let T be the timestamp of the _last_ entry of boot A in file X. The file Y
contains entries of boot A after timestamp T.
If sd_journal_seek_monotonic_usec() is called for boot A with a
timestamp _after_ T, following sd_journal_next() will provide the
_first_ entry of boot A, whose timestamp is of course earlier than T.
In the next commit, we'll introduce a varlink server for the user
manager. As preparation for that, let's introduce a new function to
initialize only the managed OOM connection whenever we send a managed
OOM update.

I don't particularly favor the duplicated strstrip()
and such, so let's ensure if we get fixed data it's
only trimmed once. Subsequently we can benefit more
by making all copies reflinks.
We initially read from temp file, then strip it, and write
back to it. If the file suddenly disappeared during the process,
it indicates someone else is touching our temp file
behind our back. Let's not silently continue.
- Add missing assertions
- Close all fds before spawning editor
- Use FOREACH_STRING() + empty_to_null() where appropriate
Note that this slightly changes the behavior, in that
empty envvars would be treated as unset and we'd try
the next candidate. But the new behavior is better IMO.

The nice value is part of struct sched_attr, and consequently invoking
sched_setattr() after setpriority() would clobber the nice value with
the default (as we are not setting it in struct sched_attr).
It would be best to combine both calls, but for now simply invoke
setpriority() after sched_setattr() to make sure Nice= remains effective
when used together with CPUSchedulingPolicy=.
