This patch ensures that subtract() between two NetworkStats object will
return a delta with no negative entries in all cases.
When the stats delta contains some negative values, there are clamped to
0. Some logging is added when this happens.
This is what's expected by NetworkStatsHistory#recordData().

This patch simplifies argument validation in NsdManager public api and
regroup duplicated validation into common methods.
This makes stack traces more actionable as now specific errors will
cause the api to throw exception from specific methods, whereas before
IllegalArgumentException would be thrown from inside the same api method
for different reasons.
This patch also includes a couple of other small cleanups.

Apps with a normal UID are typically isolated enough to not require
socket tagging; we're mostly interested in tracking down internal
UIDs that have lots of code sharing the same UID.
Also fix up everyone doing manual string checks of Build.TYPE, since
we now have first-class fields for those.

This way an app store can shift blame for update-related network
traffic onto the app that is being updated.
Using a well-known tag makes it easy for developers to identify
that they didn't explicitly request the traffic at runtime, similar
to how backup/restore traffic is handled.

Most @SystemApi methods should be protected with system (or higher)
permissions, so annotate common methods with @RequiresPermission to
make automatic verification easier.
Verification is really only relevant when calling into system
services (where permissions checking can happen on the other side of
a Binder call), so annotate managers with the new @SystemService
annotation, which is now automatically documented.
This is purely a docs change; no logic changes are being made.

Some OEMs have introduced incompatible network bookkeeping. We now
detect and ignore those network definitions at restore time.
In addition, we now
* log when an undefined network match type is used to construct a
NetworkTemplate instance, and
* quietly refuse to match such a NetworkTemplate against any known
network identifier, rather than crashing the inquiring app.

For 464xlat scenarios on IPv6 networks, the clatd interface setup
introduces double counting of apps ipv4 traffic. NetworkStatsFactory was
accounting for this on the tx path, but not on the rx path. Also it did
not accounted for the 20 bytes added by the IPv6 header.
This patch subtract correctly the rx and tx traffic from the root uid on
the underlying interface, and also adds correctly the 20 bytes cost per
packet on the stacked interface for 464xlat traffic.
Test: added several new unit tests, based on synthetic data and real
data also.

This patch uses the associative structure of the stacked/base interface
collection to avoid the two nested for loops over stacked/base
interfaces and all stats entries when correcting 464xlat traffic stats.
Consequently the list of stats entries is iterated only once.

This patch adds test coverage for NsdManager#registerService() and
NsdManager#unregisterService(). This test shows a potential defect in
the api: if unregisterService() fails, the associated listener is always
unregistered from NsdManager. If the service initially registered is
still registered, this potentially make it impossible to unregister.
Test: added new unit test
