commit 1d9661b59ca265b0ec2bbfe8673ef27096555485
Author: Tetsui Ohkubo <tetsui@chromium.org>
Date: Thu Aug 24 02:35:35 2017

Add utility function for new style notification support.

During transition to new style notification, system notification should
check IsNewStyleNotificationEnabled() and switch between
Notification::CreateSystemNotification and Notification constructor,
so the transition would not cause the regression when the flag is
diabled.
Most of the arguments are common between CreateSystemNotification and
the constructor, so it is verbose to check the flag at each call site.
This CL adds ash::system_notifier::CreateSystemNotification which checks
the flags internally.
