Previously, the sysconfig wasn't capable of understanding
carrier-associated apps that were added after a device's initial launch
(i.e. via OTA) because the logic in CarrierAppUtils explicitly avoids
disabling such apps a second time.
Most of this change is just plumbing everything through. For now, it's
all @hide due to R API deadlines. It will be made public in S.

static instance of com.android.server.SystemConfig.
