As we can't restore the contents of the cursor window, we need to keep
it on deactivation so we can restore it on requery().

Always call out to KeyguardHostView when something in our state changes.

KeyguardHostView already takes care to not add or remove the transport
control twice.
This should hopefully fix some conditions where the transport control
was still being shown although the media player already abandoned audio
focus.

Revert "Auto-close if you swipe away the last notification."

This reverts commit 8cc36e572876f3bb9197f0109db3042466e5f917.

It didn't work as advertised anyway: It only worked if there are no
persistent notifications, and it also closes the notification area if
the notification is closed by the app itself.
