fix dock audio enable dialog

The dock audio enable setting is not saved if the user
dismisses the dialog without checking or unchecking the check box.
The dialog is then displayed each time the device is docked until the
user checks/unchecks the dialog or goes to sound settings to enable
or disable dock audio.

Fix Bluetooth enable dialog to match Android style guide.

When an app requests to enable Bluetooth and/or Bluetooth discovery,
we show a dialog for user confirmation. Remove the dialog title,
update the message text and button labels to be more descriptive,
and use the standard dialog layout instead of a custom layout.

Also fixes the button layout on the Bluetooth permission test app so
that the "Discoverable" button doesn't wrap to two lines.

Better layouts for security screen setups as part of b/7459863

The major change is that choose pattern and confirm pattern layouts
no longer uses a split screen layout on tablets.  The new layout
closely mimics the layout for portrait.
Other minor changes include:
-Made the header font size for confirm pattern and choose pattern
medium (this matches with face unlock changes).
-Made the buttons on choose pattern for landscape phone side-by-side
rather than above each other (to be consistent with face unlock).
-Removed the black background from phone landscape confirm pattern
since it's inconsistent with all the other layouts.
