While I've been trying to make the GC kick in more often, I've decided
it's a better tradeoff to aggressively GC at "leisure", for multiple
reasons.
We can and should revisit this at a later time, but basically:
* The shell doesn't generate *that* much JS data - garbage collection
is very fast here.
* Long periods without GC mean we're not calling free() when we
could, which in turn makes heap fragmentation much worse.
* Ensuring the GC runs at idle makes it much less likely we'll take
a random large GC hit in the middle of an animation.

This commit introduces a "session type" for
gnome-shell. It essentially defines what
mode of operation the shell runs in
(normal-in-a-users-session mode, or at-the-login-screen mode).
Note this commit only lays the groundwork. Actually
looking at the key and appropriately differentiating
the UI will happen in subsequent commits.

shell_global_get() currently implicitly instantiates the shell
global singleton the first time it's called. This means there's
no opportunity to set construction-time properties on the singleton.
This isn't an issue yet, because there aren't any. We will need it
in the future, though, when we grow a --gdm-mode that gets exposed as
a property through the global singleton.
This commit adds a new _shell_global_init() function that must be
invoked before shell_global_get() can be called.

Adds methods to shell_global to allow taking screenshots
save the result into a specified png image.
It exposes three methods via shellDBus applications like
gnome-screenshot:
*) Screenshot (screenshots the whole screen)
*) ScreenshotWindow (screenshots the focused window)
*) ScreenshotArea (screenshots a specific area)

MetaPlugin wraps a bunch of compositor (and plain metacity) methods
that we can just call ourselves, so just do that. (Presumably this
dates back to some ancient time when it was imagined that plugins
wouldn't need access to the full metacity API.)
https://bugzilla.gnome.org/show_bug.cgi?id=654639
Rather than constantly asking mutter for the MetaScreen, and then
figuring out the MetaDisplay/Display/etc from there, just keep track
of everything we care about inside ShellGlobal.
https://bugzilla.gnome.org/show_bug.cgi?id=654639
Remove ShellGlobal's monitor-related methods, and have
Main.layoutManager provide that information instead. Move
Main._relayout() to LayoutManager, and have other objects connect to
the layout manager's 'monitors-changed' signal to know when the screen
geometry has changed.

shell_global_get_memory_info() is a new function which extracts a few
global counters we have already, namely glibc's mallinfo, spidermonkey's
JSGC_BYTES, and gjs' counters for boxed/object/etc wrappers.
There is some slight overlap with perf; ultimately though I'd
like this function to do some more extensive analysis, so it wouldn't
be quite the same.
perf is going to be mainly concerned with how big the whole process
over time is; memory_info is for debugging memory leaks.

A new envrionment variable GNOME_SHELL_ENABLE_CLEANUP is added which
causes us to attempt freeing global data. The reason this isn't
enabled by default is that it's a waste of time at best, and at
worst in corner cases could cause crashes which would fill up
crash databases. Better to leave it as a developer-only tool.
Start stubbing out some cleanup in ShellGlobal.
https://bugzilla.gnome.org/show_bug.cgi?id=649517
shell-global had become a dumping ground for functions that didn't
have anywhere else to be. Make shell-util the dumping ground instead,
and have shell-global only have methods that involve the ShellGlobal
object.

Before this change, we displayed dialogs on the monitor containing the
focused window if there was any, otherwise on monitor 0. We now use
the primary monitor rather than monitor 0 when no window has focus.

Adding correct annotations to Gio.File.load_contents revealed that gjs
doesn't actually support array+length combinations. For 3.0 this would
be invasive to fix, so add a method to ShellGlobal which does what
we need.
https://bugzilla.gnome.org/show_bug.cgi?id=646333
If you have XFixes 5 (and corresponding xserver support) then we
add barriers on the panel and in the message tray corner so that
its easy to reach the corners even when there are monitors to the
sides of the primary monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=622655
If the pointer moves on or off the stage while another process has a
grab, we will lose track of it. One example of this is that if you use
a popup menu from a message tray trayicon, the tray will stay up after
the menu goes away, because the shell never saw the pointer leave it.
Add a new method shell_global_sync_pointer() that causes clutter to
recheck what actor is under the pointer and generate leave/enter
events if appropriate.
Of course, we can't actually tell for sure when another process has a
grab, so we need a heuristic of when to call this. Currently we call
it from Chrome._windowsRestacked(), which is not really the right
thing at all, but does fix the menu-from-trayicon case...

Move the "system notification error" handling out of
util.js, and add it to ShellGlobal so we can start
calling it from across the codebase better (including
C).

This is another workaround for the lack of gjs supporting array
arguments, this time wrapping tp_connection_upgrade_contacts to
add new features to the connection's self contact.

Build gnome-shell as a binary linked against libmutter-wm, instead of
a module to be loaded by libmutter-wm. Move the majority of
initialization-type stuff from gnome_shell_plugin_start() into main().
We still build libgnome-shell as a shared library, so that the linker
doesn't discard all the methods that are never called from C.

Unfortunately the evolution-data-server client-side libraries seem to
block the calling thread. This is a major problem as we must never
ever block the main thread (doing so causes animations to flicker
etc.). In the worst case, this problem causes login to hang (without
falling back to fall-back mode) and in the best case it slows down
login until a network connection is acquired.
Additionally, in order to sanely use these evolution-data-server
libraries, GConf has to be involved and GConf is not thread-safe. So
it's not really feasible just moving the code to a separate
thread. Therefore, move all calendar IO out of process and use a
simple (and private) D-Bus interface for the shell to communicate with
the out-of-process helper.
For simplification, remove existing in-process code since internal
interfaces have been slightly revised. This means that the shell is no
longer using any native code for drawing the calendar dropdown.

See commit f2158218bef0c51 in mutter. Basically, we need
to grab org.freedesktop.Notifications before anything else
in the session gets started.
Note: I intentionally removed the Util.killall bits. I believe that
for notification-daemon at least, if we specify
DBUS_NAME_FLAG_REPLACE_EXISTING, we'll take over the name. Not sure
about notify-osd; if that's still a problem, then what we need to do
is add killing (and possibly respawning) of notify-osd to
"gnome-shell --replace", and not have it embedded randomly in a JS file.

Using clutter_get_current_event_time can result into too old timestamps
when there is no current Clutter or Mutter event, since
clutter_get_current_event_time() returns the timestamp of the last event
delivered to Clutter. This can result in, for example, grabs failing. Use
the event time of the current event (if any) and CurrentTime otherwise.

Add the machinery to cancel the notification when a new playing a
new one (wrapping ca_context_cancel), then use it when scrolling
the status icon.
Not doing it for the slider because it causes noise, either with the
keyboard, with mouse drag or with mouse wheel.

The gnome-panel allows the user to hover over a tasklist entry
while draging to activate a minimized or obscured window and drop onto it.
Implement a similar behaviour by allowing draging to the activities button or
the hotcorner (and thus opening the overview), which allows the user to
activate any window (even on different workspaces) as a drop target.

The code to draw the root background has now been moved into Mutter,
with added smarts to not draw obscured portions. Remove the old
version of the code and clone the Mutter background actor to draw
the background in the overview.

MutterWindow and MutterPlugin have been renamed to MetaWindowActor
and MetaPlugin, mutter_plugin_list_windows() to
meta_plugin_list_window_actors(). Adapt to those changes.

Gjs changed to separate the "basic" API from "embedder" API. Unfortunately
due to our use of the importer API and a few other bits, we need to use
the "module" one. In the future I plan to extend the core API to
support this use case.
Add volume control indicator which uses API from gnome-volume-control
to interact with PulseAudio and shows both input and output volumes.
Also adds a small wrapper around libcanberra in ShellGlobal, used by the
volume indicator to provide auditive feedback.
