This patch loosens the validation checks when a NetworkAgent updates it
NetworkCapabilities: instead of checking that capabilities labeled as
"immutable" stay identical across updates, it is now accepted to change
immutable capabilities in a way that the new NetworkCapabilities
satisfies the old NetworkCapabilities.
This allows a NetworkAgent to update itself in order to match more
requests, but will still catch NetworkAgents that sends degradation
updates causing potentially requests to not match anymore.

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.

This patch improves the wtf() logging in updateCapabilities to
better distinguish between the cases of a changed specifiers, changed
transports, or changed capabilities. The case of NOT_METERED being added
or removed is ignored.

Currently, netd is the only source of tethering statistics.
In order to support multiple sources, define a new
ITetheringStatsProvider interface that can be registered with
NetworkManagmentService. Convert the existing code into the
first ITetheringStatsProvider.

This patch adds a InitialConfiguration class to IpManager for specifying
IP information in IpManager ProvisioningConfiguration at IpManager
startup.
At the moment this InitialConfiguration is not used, but is validated in
startProvsiioning if ProvisioningConfiguration includes one. It will be
integrated into IpManager IP provisioning logic in follow-up patches.
This patch also includes an example of data driven unit tests using a
table of test case. The highlights of this methodology are:
1) easy extensibility for new test case,
2) rich and informative error messages,
Unfortunately Java support for inlined data structure literals is poor
and some companion static methods for data generation are required for
enabling this methodology.
