-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.

When fetching system services early during boot, if the underlying
binder interface hasn't been published yet, we end up caching a
manager class that is broken for the remainder of the process
lifetime, and innocent downstream callers end up using the broken
cached manager.
Fix this by using an explicit exception to quickly abort manager
creation when the underlying binder is missing. The exception is
only used to skip the remainder of the manager creation, and it
doesn't actually crash the process.

Callbacks
- DataUsageCallback renamed to UsageCallback
- DataUsagePolicy removed; passing in params directly to register method
- making it an abstract class
- passing in (networkType, subscriberId) that reached its threshold
- renaming onLimitReached to onThresholdReached to match existing naming
- only monitor single network,subscriberId
- no monitoring of specific uids; using device or user wide instead
Tags
- only owner uid can read its tags
- exposing only TAG_NONE to match service side

Added not_metered capability to a mobile network if none
of its associated APN types are metered. Also used not_metered
capability to determine if a network should be accounted for
data usage or not instead of using network type, which is
always MOBILE after refactoring. Will add VT usage support
in next phase.

Granular per-UID network statistics can be used to infer user
behavior over time, so they fall under the umbrella of the
PACKAGE_USAGE_STATS permission.
Since we can't check app-ops based permissions in the kernel, the
best we can do is redirect users to the NetworkStatsManager class,
which offers a much more robust historical data set.

Apps making calls into the system server may end up persisting
internal state or making security decisions based on the perceived
success or failure of a call, or the default values returned.
The reality is that if the system process just died, init will be
along shortly to kill all running apps, so we should have no problem
rethrowing the RemoteException as a RuntimeException.

Similar to first patch, but now using new "rethrowFromSystemServer()"
method which internally translates DeadObjectException into
DeadSystemException. New logic over in Log.printlns() now
suppresses the DeadSystemException stack traces, since they're
misleading and just added pressure to the precious log buffer space.
Add some extra RuntimeInit checks to suppress logging-about-logging
when the system server is dead.

NetworkStatsService will register data usage requests
and keep data usage stats scoped to the request.
There are different types of data usage requests
- scoped to a set of NetworkTemplate; these are restrictred to
device owners and carrier apps and allow the caller to monitor
all activity on the specified interfaces.
- scoped to all uids visible to the user, if the user has
android.Manifest.permission#PACKAGE_USAGE_STATS permission.
The set of uids may change over time, so we keep track of that.
- scoped to a set of uids given by the caller, granted that
the caller has access to those uids.
- scoped to the caller's own data usage. This doesn't require
PACKAGE_USAGE_STATS.
