Modify config to support app specific themes [1/4]

Summary of Changes
1. The configuration now supports each app to have their own theme.
Each theme can include icons, styles (ie overlays) and font.

2. The theme config is serialized into a json string and stored
in secure settings.  This entry consolidates what was previously 3 separate
keys (style, icon, font) into a single field.

3. 'CustomTheme' was renamed to 'ThemeConfiguration'.

Note: This commit is for the configuration. Additional work needs to be done to
the framework and UI to support app specific themes.

Support theming navbar separately from SystemUI

This allows using a different theme for the navbar than the theme
applied to the rest of SystemUI.  This will not affect theming until
we have the front end in place that allows users to change this.

Allow specifying a theme when creating a Context

A Context normally loads the resources associated with the given
package that this context is for.  This patch allows us to specify
a theme we want attached to a given context's resources.

Use systemui's applied theme for notifications.

Notifications contain RemoteViews which are inflated using the
application's context for which this notification belongs to.  This
can look out of place if SystemUI is using a different theme than the
rest of the system.

This patch will use SystemUIs theme when inflating the RemoteViews,
giving us a more consistent look in the notification drawer.

SystemUI: fix up navigation cursor keyevent flags

Volume cursor controls use slightly different flags to keep the cursor
within the field. Match them in the SystemUI for consistent (and better)
behavior.

MountService: Check for null pointer when looking for vold code

* There is actually no code path that will set an event into
  NativeDaemonConnectorException, so any reference to the event code
  will result in a null pointer exception, taking down MountService and
  the rest of the system with it.

SystemUI: fix up initial cursor down flags on nav bar

We were using the regular flags for the initial ACTION_DOWN event so the
FLAG_KEEP_TOUCH_MODE was not being passed and allowed the cursor to jump
out of bounds slightly.

SystemUI: fix nav bar layout while toggling cursor keys with an IME up

Previously there was no option to have the IME up on that settings
screen so this was not a concern before; however, with the addition of
searchable settings, it seems users are now trying to toggle it with the
IME active, putting the nav bar in a strange state becuase it did not
restore the previous states properly.
