Teach running applications to refresh already loaded ApplicationInfo
objects without resorting to restarting the application process.
Activities will be scheduled for restart via the regular life-cycle.
This is similar to a configuration change but since ApplicationInfo
changes are too low-level we don't permit apps to opt out.
This change is intended to be used with runtime resource overlays and
split APKs.
