This patch introduces between ConnectivityManager and
ConnectivityService a mechanism for propagating back to clients
informative errors in the form of error codes and associated custom
runtime exceptions.
Without error code, the service can only throw a limited number of
different exceptions over Binder. Furthermore the throw site stack
traces are always loss. Although for individual instances of a throw,
the error message can be inspected, aggregations of stack traces from
app crashes sanitize error messages and only leaves the stack traces.
This makes debugging dificult for some service calls such as
requestNetwork that can have a variety of failure modes.
In this patch only one failure mode is codified. More can be added later
at a light cost by: 1) defining an error code, 2) defining an
associated exception, 3) mapping the code to the exception. This patch
can serves as a template for doing so.
Test: $ runtest frameworks-net,
#testNetworkRequestMaximum() detects the new exception type.

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.

Wifi Aware networks are per app - i.e. a requestor gets
a dedicated network. Change verifies that the only the
original requestor matches the created network (using UID).

This groups them together with the rest of the networking unit
tests. It also speeds up compile/test cycles ("runtest -x" of one
file goes from 1m15s to 30s).

This allows an application that knows how to provide seamless
network connectivity (e.g., using QUIC multipath) to find out if
doing so is desired.

Firewall rules don't work on 464xlat because they were created under
an assumption that there's only one address for the server and it's
ipv4, which doesn't go so well when we're on an ipv6-only network.

This cleanup helps declutter ConnectivityService, and encapsulates the
always-on setting inside of Vpn instead of spreading it across two
classes.
In particular having the save code in one file and the load code in
another file was weird and I apologise for that.
Added a SystemServices wrapper for Settings.Secure and PendingIntent
calls to decouple some of the global state nastiness and make it
testable without forcing ConnectivityService to drive the load/save.

The state that needs to be transferred includes:

- whether the network is currently suspended
Additionally:
- Rename notifyNetworkCallback() to notifyNetworkAvailable()
in order to clarify its real function.

If either enableNat() or startInterfaceForwarding() fail, be sure
to cleanup any commands that might have succeeded.
Most of this change is a refactoring of cleanupUpstreamIface() into
two methods, one of which (cleanupUpstreamInterface()) is reused
in error handling scenarios.
