During an OTA, if a system app is replaced, keeping the same
directory but changing the package name, it's possible to have
a phantom disabled system package setting. In this scenario,
check that the disabled system package is actually backed by
a package.

Fixes: 65367640
Test: Manual
Test: Create /system/app/Foo/Foo.apk
Test: upgrade app [adb install -r com.foo]
Test: Replace /system/app/Foo/Foo.apk w/ a new package name

When a carrier provides an "anchor" of data usage at a specific
moment in time, augment the network statistics used by warning/limit
thresholds and Settings UI.  For example, if the OS measured 500MB
of usage, but the carrier says only 400MB has been used, we "squish"
down the OS measured usage to match that anchor.

Callers using the hidden API will have their data augmented by
default, and the public API offers a way to opt-into augmentation.

Thorough testing to verify behavior.

Observable state needs to be fully established by the time the
caller is allowed to proceed, otherwise they might read stale
information.  In particular, we hadn't yet committed changes to
the backing store by the time observers were released, so they
could then read a stale generation number as the "current" state.

With this fix, the flaky CTS test is now reliably passing.
