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.

Add a small tracking object to enforce maximum
quotas for SPIs, Transforms, and Encap sockets. The
current quota limits are intentionally conservative
with the expectation that we can relax them more
easily than we can shrink them.

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.

This patch changes NsdService to call registerContentObserver in the
ContentResolver class indirectly through NsdSettings.
This allows to easily intercept it and mock it in unit tests, and solves
test failures on the internal master branch where
registerContentObserver uses final or static methods that cannot be
worked around.

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.
