The changes to enforce single handling of all key events were breaking
custom-alt-tab keypress handlers, since that code was assuming that
key event would get to process_tab_grab(), and then maybe to
process_event() and then to the plugin's xevent_filter to detect a
key release.
We centeralize all of this handling into process_tab_grab() and either
- Invoke a custom handler for the key press
- Select the current window on modifier release by calling a new
pseudo-binding "tab_popup_select"
- Cancel the grab on an unbound key by calling a new pseudo-binding
"tab_popup_cancel"

mutter_plugin_begin_modal() and mutter_plugin_begin_modal() allow putting
a plugin into a "modal" state. This means:
- The plugin has the keyboard and mouse grabbed
- All keyboard and mouse events go exclusively to the plugin
mutter-plugin.[ch]: Add public API
compositor.c compositor-private.h: Implement the API
mutter-plugin-manager.c: When reloading plugins, make sure none of them
are modal at that moment, and if so force-unmodal them.
common.h: Add META_GRAB_OP_COMPOSITOR
display: When display->grab_op is META_GRAB_OP_COMPOSITOR forward relevant
events exclusively to the compositor.

Only process each key event once. If all keys are grabbed, then
don't also look for handlers for a key shortcut after processing
the grab op. If all keys are grabbed or we find a key shortcut,
don't pass the event on to the compositing mananger.

The previous notification code was attempting to use the "modified"
boolean returned from set_title_text, but "that boolean doesn't mean
what you think it means". It actually means "I truncated the title".
Just always notify, it's far simpler than trying to compute
when we don't need to, and callers can compress if they really need
to.
mutter-window.c originally grew an #include "window-private.h" for
window->override_redirect, but that was just fixed. However since
then it also ended up relying on a few other minor private bits.
To fix that, add meta_window_is_mapped, promote meta_window_toplevel_is_mapped
to public, and use the public MetaDisplay accessor.
The functionality to propagate errors for other displays to other
a "foreign error handler" was Soeren's compositor and is no longer
being used. Remove it.
(Now that error.h is being installed and scanned, we need to either
do this or add XErrorEvent to xlib-2.0.gir and rename ErrorHandler
to MetaErrorHandler. This way is a bit simpler.)
When we first start up, we do not want to run effects on any pre-exising
windows (this is either the case we are starting up and there are no windows,
or we are replacing an exisint window manager, or worse, we crashed, and we
just want to get to the desired desktop as quick as possible).
Dithered about where to place the check; putting into the plugin manager
reduces the number of places (and files) in which it needs to be done.
