We'll use this in gnome-shell to freeze the keyboard right before
switching input source and unfreeze it after that's finished so that
we don't lose any key events to the wrong input source.

If a binding is updated with a clear set of strokes (effectively
disabling it) we aren't signaling that the binding changed and thus
the previous strokes will continue to be grabbed.
This fixes that and tries to do a better effort at checking if the
binding changed or not.

gnome-shell has traditionally just called XSetInputFocus when wanting to
set the input focus to the stage window, but this might cause strange,
hard-to-reproduce bugs because of an interference with mutter's focus
prediction. Add API to allow gnome-shell to focus the stage window that
also updates mutter's internal focus prediction state.

If an app pops up an OR window and sets input focus to it, like
Steam does, we'll think the focus window is null, causing us to
think the app is not focused.
OR windows should not be special if they get input focus, where
the input focus would be set to NULL. Instead, the window should
be marked as focused.

Mutter previously defined display->focus_window as the window that the
server says is focused, but kept display->expected_focus_window to
indicate the window that we have requested to be focused. But it turns
out that "expected_focus_window" was almost always what we wanted.
Make MetaDisplay do a better job of tracking focus-related requests
and events, and change display->focus_window to be our best guess of
the "currently" focused window (ie, the window that will be focused at
the time when the server processes the next request we send it).

Make it a static function for now, but this will be a private
function soon, replacing meta_window_lost_focus. This should
contain no functional changes, only cosmetic indentation changes,
so best viewed with ignorews=1 or -w or -b, you know the drill.

Clients using _NET_WM_MOVERESIZE to start a drag operation may encounter
a race condition if the user presses and releases a mouse button very
fast, getting "stuck" in a grab state. While this is easily fixed with
the user pressing the button or hitting Escape as the EWMH spec suggests,
its's still a bit of annoyance for users.
After starting a grab operation, check that the button is actually pressed
by the client, and if not, cancel the grab operation. This prevents the
stuck grab in a race-free way, although it requires an extra round-trip
to the server.
With client-side decorations becoming more popular, the use of
_NET_WM_MOVERESIZE is on the rise, thus this bug is seen more frequently
than before.

As we only had one string-array preference so far, we didn't bother
with adding a generic way to handle string-array preferences, and
just handled the preference in question explicitly. However we are
going to parse another string-array setting, so generalize the
existing code to make it reusable for that case.

This essentially just moves install_corners() from the compositor, through
the core, into the UI layer where it arguably should have been anyway,
leaving behind stub functions which call through the various layers. This
removes the compositor's special knowledge of how rounded corners work,
replacing it with "ask the UI for an alpha mask".
The computation of border widths and heights changes a bit, because the
width and height used in install_corners() are the
meta_window_get_outer_rect() (which includes the visible borders but not
the invisible ones), whereas the more readily-available rectangle is the
MetaFrame.rect (which includes both). Computing the same width and height
as meta_window_get_outer_rect() involves compensating for the invisible
borders, but the UI layer is the authority on those anyway, so it seems
clearer to have it do the calculations from scratch.

XUngrabKey() doesn't work for XI2 grabs and XI2 doesn't provide API
with similar functionality. As such, we have to refactor the code a
bit to be able to call XIUngrabKeycode() for each key binding, then
reload keybindings and finally grab the new ones.

In 97a4cc8c, we accidentally lost the check that kept us from
sending multiple configures to a window before it responds to
_NET_WM_SYNC_REQUEST. So _NET_WM_SYNC_REQUEST stopped working
properly. Add a check back with the same effect.

During a resize, if we don't have a configure pending, then a counter
change shouldn't trigger anything other than the normal drawing:
it's just a spontaneous frame from the application. So don't try
to update the position or remove our timeout ID.

Trying to track the fullscreen status outside of Mutter, as GNOME Shell
was doing previously, was very prone to errors, because Mutter has a
very tricky definition of when a window is set to be fullscreen and
*actually* acting like a fullscreen window.
* Add meta_screen_get_monitor_in_fullscreen() and an
::in-fullscreen-changed signal. This allows an application to
track when there are fullscreen windows on a monitor.
* Do the computation of fullscreen status in a "later" function that
runs after showing, so we properly take focus into account.
* To get ordering of different phases right, add more values
to MetaLaterType.
* Add auto-minimization, similar to what was added to GNOME Shell
earlier in this cycle - if a window is set to be fullscreen, but
not actually fullscreen, minimize.

Since the tile mode is now always reset on maximize(), this code
no longer does anything (not to mention that side-by-side tiled
windows haven't snapped back for a while now).
https://bugzilla.gnome.org/show_bug.cgi?id=682779
We used to restore side-by-side tiling when unmaximizing, so we
kept the tile-mode during maximization. Since commit 10d53fc7d
there's no longer a good reason to do so, and it can result in
tile previews being shown erroneously on window drag operations
without motion (double-click on titlebar), so reset the tile
mode in maximize().
https://bugzilla.gnome.org/show_bug.cgi?id=682779
The tile preview is expected to be shown underneath the focus window.
However the code that restacks the preview broke when override-redirect
windows were moved to a separate window group.
To fix, special-case tile previews to put them in the NORMAL layer.

Previously, we were handling failure to respond to _NET_WM_SYNC_REQUEST
in the code path for throttling motion events. But this meant that
if a window didn't respond to _NET_WM_SYNC_REQUEST and there were no
motion events - for a keyboard resize, or after the end of the grab
operation - it would end up in a stuck state.
Use a separate per-window timeout to reliably catch the failure to respond
to _NET_WM_SYNC_REQUEST.

During resizing we froze window updates when configuring the
window, and unfroze the window updates when processing the
next resize. This wasn't absolutely reliable, because we might
not have a next resize. Instead tie window freezing more
directly to the current sync request value - a window is
frozen until it catches up with the last value we sent it
in _NET_WM_SYNC_REQUEST.
Testing with unresponsive clients showed that there was a bug
where window->disable_sync once set, would not actually disable
sync, but it *would* disable noticing that the client was
unresponsive for the next resize. Fix that by checking for
->disable_sync before sending _NET_WM_SYNC_REQUEST.
https://bugzilla.gnome.org/show_bug.cgi?id=694046
Send a _NET_WM_FRAME_DRAWN for each newly created window, as required
by the specification. This avoids a race where a window might be created
frozen but already unfrozen by the time we first see fetch the
counter value.
Remove a duplicate call to meta_compositor_set_updates_frozen() which
was called before the MetaWindowActor is created and hence did nothing.

mutter currently only filters the overlay key through the shell
when there is a grab operation and that grab operation belongs to the
shell (because the shell is pushModal'd). This means the shell can't
filter out overlay key press events events at startup (since the shell
isn't normally modal).
This commit changes the code to always run the shell filtering code,
even when the shell is not modal.

gnome-shell shouldn't announce to the session manager it's
"ready" until it's fully initialized. It currently tells
the session manager it's ready as soon as it hits the main
loop. This causes nautilus in classic mode to start before
we have workspaces initialized.

During compositor grabs, all global keybindings that don't go
through mutter's keybinding system are blocked. To allow other
processes to make use of it, gnome-shell will expose a simple
grab API on DBus; for this, add API to grab key combos directly
instead of parsing accelerators stored in GSettings.

meta_screen_get_monitor_for_rect will return the monitor that
a given rect belongs in (choosing the "best" monitor based on

meta_window_is_remote compares a cached copy of the system hostname
with the hostname of the client window
(as presented by the WM_CLIENT_MACHINE property).
Of course, the system hostname can change at any time, so caching
it is wrong. Also, the WM_CLIENT_MACHINE property won't necessarily
change when the system hostname changes, so comparing it with the
new system hostname is wrong, too.
This commit makes the code call gethostname() at the time
WM_CLIENT_MACHINE is set, check whether it's remote then, and cache
that value, rather than comparing potentially out of sync hostnames
later.

Window menus use the first key combination for a binding to show the
