Add new API for handling privacy privileges during application launch
New public function security_manager_prepare_app_privacy() to be called
by launcher. It will check application policy, generate pop-up if necessary,\
wait for user answer, modify policy accordingly and trigger toast message
if application launch has been prohibited.
The caller (launcher) should abort application launching if this function
returns an error.
