glwallpaper requests a GL context with low priority, however this
feature is a GL extension that may not be available in the GL
implementation (swiftshader, for example).

This moves functionality around snapshotting, restoring, and deleting app data,
and enabling rollbacks, into the Rollback class.

Note that the new methods still rely on the AppDataRollbackHelper class - that
functionality may be combined into Rollback in future but those changes are not
in scope for this CL.

This is part of a series of changes to move rollback-specific functionality
into the Rollback class. Once these are completed, synchronisation can be
moved to be internal to Rollback, and the internal state of the Rollback class
can be cleaned up.

This moves functionality around making rollbacks available, and committing
rollbacks, into the Rollback class. This allows access to the state itself
to be made private within Rollback.

- When user leaves WiFi control page, ApplicationState session
is onpause(), and removes all handler callback. But if a callback
is fired, remove callback can not remove it. Therefore Wifi callback
is received in Special app access page which is loading DataUsageState.
It caused object cast error because wifi callback want to cast
DataUsageState data to WifiSettingsState.
- The solution is do not rebuildList in paused state.
