Followup to previous commit. Suggested by @poettering.
Reindented the `verbs[]` tables to match the apparent previous
whitespace rules (indent to one flag, allow multiple flags to overflow?).

A lot of code references the `running_in_chroot()` function; while
I didn't dig I'm pretty certain this arose to deal with situations
like RPM package builds in `mock` - there we don't want the `%post`s
to `systemctl start` for example.
And actually this exact same use case arises for
[rpm-ostree](https://github.com/projectatomic/rpm-ostree/)
where we implement offline upgrades by default; the `%post`s are
always run in a new chroot using [bwrap](https://github.com/projectatomic/bubblewrap).
And here's the problem: bwrap creates proper mount roots, so it
passes `running_in_chroot()`, and then if a script tries to do
`systemctl start` we get:
`System has not been booted with systemd as init system (PID 1)`
but that's an *error*, unlike the `running_in_chroot()` case where we ignore.
Further complicating things is there are real world RPM packages
like `glusterfs` which end up invoking `systemctl start`.
A while ago, the `SYSTEMD_IGNORE_CHROOT` environment variable was
added for the inverse case of running in a chroot, but still wanting
to use systemd as PID 1 (presumably some broken initramfs setups?).
Let's introduce a `SYSTEMD_OFFLINE` environment variable for cases like
mock/rpm-ostree so we can force on the "ignore everything except preset" logic.
This way we'll still not start services even if mock switches to use nspawn or
bwrap or something else that isn't a chroot.
We also cleanly supercede the `SYSTEMD_IGNORE_CHROOT=1` which is now spelled
`SYSTEMD_OFFLINE=0`. (Suggested by @poettering)
Also I made things slightly nicer here and we now print the ignored operation.

Given that we regularly have verbs that require privileges, let's just
make this a flag of the verb.

This should be handled fine now by .dir-locals.el, so need to carry that
stuff in every file.

This adds some basic infrastructure in order to fix #2015.

The patching of elogind in several steps with only partly rebasing on
a common commit with upstream, left the tree in a state, that was
unmergeable with master. By rebasing on master and manually cleaning
up all commits, this merge is now possible.
However, this process left some orphans, that are cleanup now.

This commit replays the moving around of source files that have been
done between systemd-219 and systemd-221.
Further the Makefile.am is synchronized with the upstream version and
then "re-cleaned".
A lot of functions, that are not used anywhere in elogind have been
coated into #if 0/#endif directives to further shorten the list of
dependencies.
All unneeded files have been removed.
