Fix double finger when 'Quick pull down' is disabled.

If "Quick pull down" is disabled, never do the function "switchToSettings()" and the stock double-finger feature doesn't work.
The OTS preferences only need to check the "statusbar portion" code.

Framework: Create "on-the-spot" preference dialog only if needed

Right now a new instance of the "on-the-spot" preference dialog gets created
each time when the user taps on the immersive tile or each time when the
user pulls the statusbar from the right side. It should only be created if
it's really needed.

PS2: RecentsActivity clear all
PS3: Made method static and check is in SettingConfirmationHelper
	(thanks to Yamil!) + rebase ("Long press recents to switch to last
	 app"
PS4: Removed unneeded variable

Kill floating activities running in the same thread when tapping outside

This change makes all activities from the same app to be finished when we tap outside the halo window. Other apps running in different threads
(floating or not) won't be finished.

frameworks/base: Fix change propagating issue

destroyLayer() function has been modified in kk. It is not correct
to propagate the UI corruption fix from jb to kk without considering
the new changes made in kk. This change is to make it align with
the new code in kk.
