Usage stats corrections for 464xlat in NetworkStatsFactory are not applied
to tethered traffic. Add adjustments in NetworkStatsService. After
migrating external callers off NetworkStatsFactory, we will be able to
only apply adjustments in NetworkStatsService and remove stacked
interface tracking from NetworkStatsFactory.

The owned by transform flag prevents the removal
of an SPI from accidentally deleting an associated
SA in the kernel. That flag wasn't actually being
checked, so deleting an SPI would result in the
transform being removed.
The existing code already guarantees that the SA is
deleted when the transform is deleted

Currently, when a network goes into CONNECTED state, we call
updateLinkProperties and then notifyIfacesChangedForNetworkStats.
The latter is unnecessary, as there are exactly two cases:
1. networkAgent.linkProperties != null: updateLinkProperties will
call notifyIfacesChangedForNetworkStats, because oldLp is null
and networkAgent.linkProperties is not null.
2. networkAgent.linkProperties is null: there is no need to call
notifyIfacesChangedForNetworkStats, because no interfaces were
added or removed. When they are, updateLinkProperties will be
called again.
Removing the call to notifyIfacesChangedForNetworkStats avoids
a stats poll, which is a minor performance improvement.
Also, remove the NetworkStatsService code to do asynchronous
interface updates, since it has no callers.

Now that we have a nice Clock abstraction, we can use it to represent
a clock backed by an NTP fix. (This makes testing logic much easier
to write.)
We now rely completely on NetworkTimeUpdateService to keep our NTP
fix up to date, instead of trying to refresh in the middle of
critical paths which could trigger random ANRs.
Add internal FallbackClock to make it easier to handle missing NTP
fixes. Add internal SimpleClock to let implementers focus on single
millis() method.

- add Ethernet interface configurations to config.xml; no vendors can
specify network capabilities (in particular they can mark network as
restricted which make sense for embedded applications + static IP
configuration)

name as an identificator
- extend IpConfigStore to store IP configuration based on string
identifier (e.g. ethernet name)
