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().

Currently, we only count add tethering traffic to per-UID
stats, but not to total data usage (i.e., dev and XT stats). This
is correct for software tethering, because all software forwarded
packets are already included in interface counters, but it is
incorrect for hardware offload, because such packets do not
increment interface counters.
To fix this:
1. Add an argument to ITetheringStatsProvider#getTetherStats to
indicate whether per-UID stats are requested. For clarity,
define integer constants STATS_PER_IFACE and STATS_PER_UID
to represent these operations.
2. Make NetdTetheringStatsProvider return stats only if per-UID
stats are requested. (Otherwise tethering traffic would be
double-counted).
3. Make OffloadController's stats provider return the same
stats regardless of whether per-UID stats were requested or
not.
4. Make NetworkStatsService add non-per-UID tethering stats to
the dev and XT snapshots. The per-UID snapshots were already
correctly adding in per-UID stats.

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.

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 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.

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

This patch adds basic logging to NsdManager and NsdService, and improves
the facilities for pretty printing the event ids defined in NsdManager.
It also includes a few minor cleanups:
- adding 'final' on effectively final instance variables of NsdManager
and NsdService.
- similarly, adding 'static' on effectively static class fields.
- regrouping instance variables together.

Because there is no way using the Java sockets API to actually
get a socket of AF_INET on mode machines, it is necessary to
provide a way to apply transforms to sockets made using the
native wrapper API, which uses POSIX APIs and will create a
socket that is AF_INET.
