This is a rather large change which moves
the add and install logic into edit-util.
We store an EditFile array and the number of
elements, along with the edit markers used in
temporary files and whether to remove the parent
directories of the target files if they're empty
in an EditFileContext object.
Call edit_files_add() to add an file to edit,
and do_edit_files_and_install() to do the actual
editing (through create_edit_temp_file(),
run_editor() and trim_edit_markers()).
After that, edit_file_context_done() can be used
to destroy the object.
In various tools and services we have a per-system and per-user concept.
So far we sometimes used a boolean indicating whether we are in system
mode, or a reversed boolean indicating whether we are in user mode, or
the LookupScope enum used by the lookup path logic.
Let's address that, in introduce a common enum for this, we can use all
across the board.
This is mostly just search/replace, no actual code changes.
Otherwise under certain conditions `va_arg()` might get garbage instead
of the expected value, i.e.:
$ sudo build-o0/systemctl disable asdfasfaf
sd_bus_message_appendv: Got uint64_t: 0
Failed to disable unit: Unit file asdfasfaf.service does not exist.
$ sudo build-o1/systemctl disable asdfasfaf
sd_bus_message_appendv: Got uint64_t: 7954875719681572864
Failed to disable unit: Invalid argument

Related issue: https://github.com/systemd/systemd/pull/14470#discussion_r362893735
If the default target is masked, `systemctl get-default` prints
Failed to get default target: Operation not possible due to RF-kill
That's a bit too cryptic, so let's make it clear what's actually
happening.
Fixes#26589.
- Rename struct socket_info -> SocketInfo.
- Drop own_triggered field, and always copy the triggered field.
- Use CLEANUP_ARRAY().
No functional changes, just refactoring.
We would print:

The "left" part uses precious screen estate and is pretty much implied
by the column name. Drop it.
usec_t is also a uint64_t internally, hence this doesn't actually change
anything. However, on the conceptual level, sd-bus expects a uint64_t
hence give it one.
Timespans are probably best right-aligned, in particular if they
systematically end in either " ago" or " left" because they are used as
"relative timestamps".
Only service and scope units have RuntimeMaxUSec bus property.
To suppress the "Until:" field for other unit types, the entry must be
initialized with USEC_INFINITY.
Fixes#26473.
This allows accompanying a signal with a value (as supported for Linux
Realtime signals). This is particularly useful as it allows us to do
stuff like this:
systemctl kill --kill-whom=main --kill-value=0x300 systemd-journald
In order to ask journald to flush its allocation caches and compact
memory.
