The LoginManager abstraction is still mostly callback-based, not
least because the methods are thin wrappers around logind D-Bus
calls.
However as gjs' dbus wrapper now generates promised-based wrappers
as well, we can implement a proper async API just as naturally.

Introduce a new class, EventEmitter, which implements signal
handling for pure JavaScript classes. EventEmitter still
utilizes GJS' addSignalMethods internally.
EventEmitter allows static typechecking to understand the
structure of event-emitting JS classes and makes creating
child classes simpler.
The name 'EventEmitter' mirrors a common name for this pattern
in Node and in JS libraries.

Promises make asynchronous operations easier to manage, in particular
when used through the async/await syntax that allows for asynchronous
code to closely resemble synchronous one.
gjs has included a Gio._promisify() helper for a while now, which
monkey-patches methods that follow GIO's async pattern to return a
Promise when called without a callback argument.
Use that to get rid of all those GAsyncReadyCallbacks!

ES6 allows to omit property names where they match the name of the
assigned variable, which makes code less redunant and thus cleaner.
We will soon enforce that in our eslint rules, so make sure we use
the shorthand wherever possible.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/805
While we aren't using those destructured variables, they are still useful
to document the meaning of those elements. We don't want eslint to keep
warning about them though, so mark them accordingly.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/627
We are currently inconsistent with whether or not to put a space
after catch clauses. While the predominant style is to omit it,
that's inconsistent with the style we use for any other statement.
There's not really a good reason to stick with it, so switch to
the style gjs/eslint default to.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/607
ES6 finally adds standard class syntax to the language, so we can
replace our custom Lang.Class framework with the new syntax. Any
classes that inherit from GObject will need special treatment,
so limit the port to regular javascript classes for now.

If we're started by systemd, we won't be in the user's display session.
However, this is still the session that will get locked & unlocked. Ask
logind what the 'display' or 'greeter' session is, and watch for the
Unlock signal for that session to know when to unlock.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/137
When not using arrow notation with anonymous functions, we use Lang.bind()
to bind `this` to named callbacks. However since ES5, this functionality
is already provided by Function.prototype.bind() - in fact, Lang.bind()
itself uses it when no extra arguments are specified. Just use the built-in
function directly where possible, and use arrow notation in the few places
where we pass additional arguments.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/23
Any symbols (including class properties) that should be visible
outside the module it's defined in need to be defined as global.
For now gjs still allows the access for 'const', but get rid of
the warnings spill now by changing it.

The underlying logind API does not only indicate whether suspend is
available, but also whether the user is eligible for executing the
operation without further authentication. This information can be
relevant, so pass it to the callback.
https://bugzilla.gnome.org/show_bug.cgi?id=725960
Logind recently got support for a hint property in Session Object to
inform if session is Locked or not. It is up to desktop environments
to keep this property up to date.
https://bugzilla.gnome.org/show_bug.cgi?id=764773
According to systemd logind's documentation, the CanSuspend() method
"returns 'na' in case "the operation is not available because hardware,
kernel or drivers do not support it", while "'no' is returned if the
operation is available but the user is not allowed to execute it".
See http://www.freedesktop.org/wiki/Software/systemd/logind
Thus, we need to return true here when the reply for the CanSuspend
method is neither 'no' nor 'na', or we would providing false positives
in cases where suspension is simply unsupported.

The code path is completely unmaintained and untested (and probably
unused as well, considering that nobody has complained about accessing
the session object's Active property which does not exist in the
ConsoleKit case).
Most of our ConsoleKit code is already a dummy anyway, just do the
same for the remaining functionality.

When a user logs in to a wayland session, we keep the login screen
running on the X server with the login screen running in a deactivated mode.
This commit makes sure it get reactivated when the user comes back to
the VT (from user switching, logout or just ctrl-alt-f1).

It's important to compare the version components as integers,
not strings, so "10" evaulates as greater than "5"
This fixes the login screen in gnome 3.10.

These don't go through gnome-session, so they don't properly update
its state machine. We should use these in the future when we want to
use logind user sessions, but for now, they're just a trap.
https://bugzilla.gnome.org/show_bug.cgi?id=706612
With fallback mode dropped, we can no longer rely on gnome-screensaver
to be installed, so we'll have cases where we are unable to lock the
screen. The user menu should not show the "Lock" item in this case,
but as UnlockDialog includes UserMenu, we cannot use the existing check
without creating a circular dependency; move the function to a more
generic place to fix.
https://bugzilla.gnome.org/show_bug.cgi?id=693403
If screen locking is enabled, the screen shield should drop down
on suspend. Currently this is achieved by either explicitly locking
the screen (when selecting "Suspend" from the user menu) or by
relying on g-s-d delaying the suspension enough time for the shield
to get into place (lid close, power button).
Systemd inhibitors offer a safer way to ensure that the screen is
locked before going to sleep, so add a small abstraction for them
in the loginManager - with inhibitors being a systemd-only feature,
the ConsoleKit path only has a dummy implementation.
https://bugzilla.gnome.org/show_bug.cgi?id=686482
Logind provides a Suspend method, which we should use instead of
the UPower API when available. Expose this in loginManager, using
the UPower API for the ConsoleKit implementation.

Various code around had different paths for ConsoleKit and
logind. Consolidate it by making an abstract class that all
callers can use, which hides the implementation details of the
two daemons.
