Previously, changes to the visibility of a window could be indicated
by meta_compositor_map_window(), meta_compositor_unminimize_window(),
meta_compositor_set_window_hidden(), etc, with the exact behavior
depending on the 'live_hidden_windows' preference.
Simplify this so that visibility is controlled by:
meta_compositor_show_window()
meta_compositor_hide_window()
With an 'effect' parameter provided to indicate the appropriate
effect (CREATE/UNMINIMIZE/MINIMIZE/DESTROY/NONE.)
The map state of the window is signalled separately by:
meta_compositor_map_window()
meta_compositor_unmap_window()
And is used only to control resource handling.
Other changes:
* The desired effect on show/hide is explicitly stored in
MetaWindow, avoiding the need for the was_minimized flag.
At idle, once we calculate the window state, we pass the
effect to the compositor if it matches the new window
state, and then clear the effect to start over for future
map state changes.
* meta_compositor_switch_workspace() is called before any windows
are hidden or shown, allowing the compositor to avoid hiding
or showing an effect for windows involved in the switch.

* Handling of post-effect cleanups for MutterWindow are
simplified - instead of trying to do different things based
on the individual needs of different effects, we just wait until
all effects complete and sync the window state to what it
should be.
* On unmap, once we destroy the pixmap, we tell ClutterX11Pixmap
that we've done so, so it can clean up and unbind. (The
unbinding doesn't seem to be working properly because of
ClutterGLXPixmap or video driver issues.)

Clean up mutter_window_effect_in_progress() by removing the
include_destroy parameter which was used only in one place that
could be easily done otherwise. (There was another use in
mutter_window_sync_actor_position() that had no point and looked
unintended.)

Add a paint function that checks all windows for repair and
shape updates; this:
- simplifies the logic for when a window needs to be repaired
- avoids duplicate work when we get multiple damage effects
- avoids the need to look ahead in the event queue
Instead of relying on repair to implicitly resize the
MutterWindow actor, set the size explicitly when the core
code updates the geometry. (This is needed because we haven't
repaired yet when we start an animation, and the animation
may depend on the size to, e.g., rescale from the center.)
Because the core geometry update happens before we start
maximize/unmaximize effects we need to work around this by
passing both the old and new geometry to the compositor.

compositor.c: Move MutterWindow code to mutter-window.c;
rename map_win() to mutter_window_map(), etc.
mutter-window-private.h: New private header file for
MutterWindow functions used internally to the compositor.
compositor-mutter.h: Move MutterWindow declarations to
mutter-window.h; move a couple of private functions to
compositor-private.h
compositor-private.h: Move MetaCompScreen declaration to here:
Conceptually it's private to compositor.c, but MutterWindow
manipulates some of the lists directly for now.
mutter-plugin.c compositor.c: Don't call mutter_window_effect_completed()
for MUTTER_PLUGIN_SWITCH_WORKSPACE, but use a new
mutter_switch_workspace_completed(), since the window is
just used to identify a screen.
