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.

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 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

These methods do not currently work for IPv4 sockets,
so they need to be hidden until the underlying kernel
code can be made to work properly in a dual-stack
environment.

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.

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.
Test: no functional changes

-Remove Int-based SPI usage from the IpSecTransform.Builder
This is essentially a less-safe method overload, and it is both
unnecessary and difficult to implement: the cross-validation
between SPI and Transform is actually useful, and the kernel
requires two different mechanisms to use an unreserved vs a
reserved (alloc'd) SPI: CREATESA vs UPDATESA, which makes this
hard to support. API Council has questioned the value of this,
and they are right: everything points to "remove this". In the
future, if we find that SPI reservation is overhead, we can
always add it back.
-Hiding the TunnelMode builder method and application/remove
methods. These will not land by the time the next API
stabilizes, so better to hide them now that this is a
near-certainty. Expectation is to un-hide them in the subsequent
API bump.

To make the SPI reservation more semantically consistent with the
transform creation API, and to ensure that we always create SPI
reservations relative to a well-known remote, we should take the
SPI request relative to a remote (rather than to a destination).
This necessitates that we now consider direction separately, which
is used for keying the SA-Id.

Network usage is tracked by the kernel at the UID level, which is
granular enough for normal apps, but large components (such as the
system server) are impossible to debug without adding additional
socket tagging to help identify subsystems within a UID.
To help ensure that system components tag all their network traffic,
this change offers a new StrictMode option to detect and report
untagged sockets.

Properly account for VPN apps that make heavy use of the tun
interface. Prior to this change a VPN app could be incorrectly charged
for more data than it actually used if it sent more traffic through
the tun interface than the underlying interface.
This change excludes VPN app traffic on the tun interface from the
adjustment pool and doesn't redistribute traffic to the VPN app.
Instead all of the redistributed traffic is deducted from the VPN app
which effectively represents any overhead incurred by the VPN app.
