Recent mutter changes made MetaShapedTexture not a ClutterTexture,
but instead a special ClutterActor subclass that implemented the texture-y
bits itself. Use recently introduced API in MetaShapedTexture so that we can
get the raw texture data and spit it out as a PNG.
Use the new meta_shaped_texture_get_image() to get a window's texture data.
meta_shaped_texture_get_image() flattens the image against any mask it may
have, so a screenshot of it should look exactly as it does on the display.

For the Intel drivers, using glReadPixels() to read into client-memory
directly from the frame buffer is much slower than creating a pixel
buffer, copying into that, and then mapping that for reading. On other
drivers, the two approaches are likely to be similar in speed. Create
a ShellScreenGrabber abstraction that uses pixel buffers if available.
Use that for screenshots and screen recording.

Use the correct clip offsets when taking the screenshot of a window, to
exclude possible invisible borders and to include the case where the
window doesn't have any frame itself.
Writting the screenshot to a file can take a relativly long time
in which we block the compositor, so do that part in a separate
thread to avoid the hang.

Allow push_modal to optionally only work with a keyboard only grab and
use that in altTab as a fallback to allow switching windows while a pointer grab
is in effect (like during DND operations).

shell_global_get_memory_info tries to zero initialize the output
parameter with memset, but it passes the wrong size (because of
a missing *). There's no reason to do the memset, though. In the
normal case all members of the struct gets initialized before the
function returns anyway.
This commit drops the memset call in favor of one explicit 0 assignment
that only gets executed on on atypical platforms.

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.)

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.

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.
