cgroup path rather than audit
Previously for cases like "su" or "sudo" where a session is attempted to
be created from within an existing one we used the audit session ID to
detect this and in such a case we simple returned the session data of
the original session a second time.
With this change we will now use the cgroup path of the calling path to
determine the old session, i.e. we only rely on our own session
identification scheme, instead of audits.
We will continue to keep the audit session ID and ours in sync however,
to avoid unnecessary confusion.

The columnar output can become pretty horrible. When GNOME inhibits
power/suspend/hibernate keys, the "WHAT" column's text extends to "WHO"
and even "WHY". At the same time, all texts in "WHY" are of the form
GNOME handlin...sses
Receiving sle...ions
GNOME needs t...reen
This patch splits each inhibit entry into four lines, allowing the full
text to fit in a normal-width terminal.

Occasionally people report problem with reboot/poweroff operations hanging in
the middle. One known cause is when a new transaction to start a unit is
enqueued while the shutdown is going on. The start of the unit conflicts with
the shutdown jobs, so they get cancelled. The failure case can be quite unpleasant,
becase getty and sshd may already be stopped.
Fix it by using irreversible jobs for shutdown (reboot/poweroff/...) actions.
This applies to commands like "reboot", "telinit 6", "systemctl reboot". Should
someone desire to use reversible jobs, they can say "systemctl start reboot.target".`

This reverts commit 2826d14091e43ed3397d862dee79d09d0115c84e.
We never should generate log messages from a library.

[zj: Reworded message s/to watch/to add watch on/ to make it clear
that it was the watch init action that failed, and not the
"process of watching". I think this way it'll be clearer to
people who don't know what inotify does.]

Currently local user are being asked for an admin password when another
user is logged into the system. This does not make sense as the user has
the power to shut down the system anyway regardless if he/she knows the
password or not (by pulling the plug, battery or whatever).
So only require the admin authentification for remote sessions.

We currently enforce that seats are to be named in the form of
"seatXXX", i.e. need to begin with the 4 characters "seat". Thus,
"seat-master" would qualify as a seat name. As seat names are frequently
used as tags on devices, the "seat-master" tag might hence confuse
logind if the user decides to name a seat "seat-master".
Hence, avoid any ambuigity: let's rename the "seat-master" tag to
"master-of-seat".

- Don't allow any locks to be taken while we are in the process of
executing the specific operation, so that apps are not surprised if a
suspend/shutdown happens while they rely on their inhibitor.
- Get rid of the Resumed signal, it was a bad idea, and redundant due to
PrepareForSleep(false), see below.
- Always send out PrepareFor{Shutdown,Sleep} signals, instead of only if
a delay lock is taken.
- Move PrepareForSleep(false) after we come back from the suspend, so
that apps can use this as "Resumed" notification. This also has the
benefit that apps know when to take a new lock.

As the tree doesn't really necessarily show all device node devices and
only those are marked for uaccess it's kinda pointless showing this at
all, since it would give a pretty incomplete impression of the uaccess
information.

suspend/hibernate/hybrid-sleep
This allows clients to get asynchronous notifications for user-requested
suspend/hibernate cycles. Kernel-triggered automatic suspending is not
covered.

This should make sure that closing the lid while shutting down won't
suspend the machine but will simply cause the shutdown to complete.

New file output.h with output flags and modes.
--full parameter also for cgls and loginctl.
Include 'all' parameter in flags (show_cgroup_by_path, show_cgroup,
show_cgroup_and_extra, show_cgroup_and_extra_by_spec).
get_process_cmdline with max_length == 0 will not ellipsize output.
Replace LINE_MAX with 0 in some calls of get_process_cmdline.
[zj: Default to --full when under pager for clgs.
Drop '-f' since it wasn't documented and didn't actually work.
Reindent a bit.

[Tested in latest gnome-ostree; if accepted, I'll look at a followup
patch which fixes the other dbus_connection_send(reply, ...) calls
besides logind]
DBus messages can have a flag NO_REPLY associated that means "I don't
need a reply". This is for efficiency reasons - for one-off requests
that can't return an error, etc.
However, it's up to users to manually check
dbus_message_get_no_reply() from a message. libdbus will happily send
out a reply if you don't.
Unfortunately, doing so is not just less efficient - it also triggers
a security error, for complex reasons. This is something that will
eventually be fixed in dbus, but it's also correct to handle it in
client applications.
This new helper API is slightly nicer in that you don't have to pass
NULL to say you don't want a reply serial for your reply.
This patch also tweaks logind to use the API - there are more areas of
the code that need this treatment too.

introduce timedatectl, to change the system time (incl. RTC), timezones

Incidentally, this also fixes a typo of MESSSAGE is three places.

This is useful for systems such as kmscon which want to invoke classic
