The addition of _backgroundStack to ModalDialog broke focus
navigation, because it was interposed between the focus group root and
all of the interesting content, but since it isn't an StWidget,
st_widget_navigate_focus() was unable to navigate through it. Fix this
by moving the focus root to this._dialogLayout (inside the
_backgroundStack) instead.
Additionally, in EndSessionDialog specifically, _initialKeyFocus
wasn't being set until after opening the dialog, so it was ignored.
Also change ModalDialog.close() to clear the _savedKeyFocus that
popModal() set, so that dialogs that are repeatedly closed and
reopened will have their focus revert back to _initialKeyFocus each
time.

The lightbox will be sized to the size of its parent container,
so we need to make the parent container reliably the size of the
stage, instead of letting it be auto-sized to the size of its contents.

If you run a command from Alt+F2 that tries to get a server grab (eg,
xmag), it will fail if it starts up before the run dialog is finished
hiding.
Additionally, the run dialog currently stays focused while it is
fading out, potentially stealing keystrokes (or causing the user to
accidentally launch two copies of a program).
Change ModalDialog.close() to call popModal() immediately
Add a ModalDialog.popModal method, and call that before running the
RunDialog command. If the command succeeds, close the dialog as
before. If it fails, call ModalDialog.pushModal() to put things back
to normal before displaying the error.

1. Both functions leaked the nodes in priv->children
2. st_container_remove_all wasn't properly updating first_child and last_child
3. remove_all() is almost never right since it won't cause signal handlers
on the children to be removed. In the rare cases where it might be needed
the caller can simply use clutter_container_remove().

This is a base class to make it easier to
gain a consistent look for system modal dialogs.
It handles creating a darkened backdrop behind the dialog, setting
up buttons in the dialog, keynav, etc.
