f1b197b23b Support passing a template to NetworkStatsManager queries.
Currently, NetworkStatsManager queries and callbacks only allow
selecting network traffic based on network identifiers:
networkType, subscriptionId and networkId.  The code ends up
converting these into a template under the hood.

Now that templates can express more fine-grained queries (e.g.,
select only roaming traffic, or select only traffic that's not
on the default network) add a hidden method to pass in a
template. This should have no security implications, as all the
access controls are performed in NetworkStatsService.

92a946d09f Add getDefaultNetwork to the NetworkStats public API.
This allows an app using the public API to know whether the

(i.e., the network was selected by the system), or not (i.e.,
the network was selected by the app).

0fff56eae5 Rename create/delete transform methods
CreateTransportModeTransform and DeleteTransportModeTransform are both

to facilitate the implementation of tunnel mode, this patch renames them
to CreateTransform and DeleteTransform, along with all test names.

3e85855083 Add the default network to NetworkStats and NetworkStatsCollection.
This allows us to maintain NetworkStats entries that track
whether the traffic was on the default network.

At the moment, the stats collection code always passes in
DEFAULT_NETWORK_NO. However, this value is a no-op, since it is
not persisted to disk. Only the ident, the uid/set/tag, and the
packet/byte/operation counters are persisted.

A future change will add defaultNetwork to the ident and start
persisting it.

0d483b76f3 IpSec - API Tweak for removeTransportModeTransform
Because IpSecTransforms are now unidirectional,
and because the only mechanism for removing Transforms
removes it from both directions, the API can no longer
use the Transform parameter to meaningfully validate
that the caller had applied a transform. Since that
functionality was as-yet unimplemented and is now
infeasible, the transform parameter is removed.

3167625a15 Prevent Closure of Underlying Socket FDs
The version of applyTransportModeTransform() and
removeTransportModeTransform() that accepted
Socket and DatagramSocket were closing the underlying
FDs upon return. It's unclear whether this is due to
a behavior change elsewhere in ParcelFileDescriptor,
but either way, converting to using getFileDescriptor$
and then calling dup() explicitly rather than relying
on ParcelFileDescriptor seems like a better idea anyway.

5a19b9500d Make Transforms Unidirectional
Convert the IpSecTransform from being a bi-directional
pair of SAs to a unidirectional single SA. This CL
also removes the concept of "direction from SAs meaning
that a IpSecTransform may now be applied to a socket
in either direction.

-Make transforms unidirectional
-Add Convert allocateSpi() to use destination rather
 than direction and remote address
-Remove directionality from builders for IpSecTransform
-Change applyTransportModeTransform() to take a
 direction in which to apply the transform object.
-Additional minor naming updates
-Restrict IpSecConfig to only print keys on eng builds
-Move DIRECTION constants to IpSecManager
-Add sourceAddress parameter to IpSecTransform to provide
 additional guarantees about the source address of data;
 (explicit failure rather than implicit failure).
-Move SPI to the build() method of IpSecTransform

fdafce24cf IpSecService - Convert mNextResourceId from AtomicInt to Int
The mNextResourceId variable is only accessed within synchronized

it. This eliminates the misleading notion that the variable is
accessed outside of guarded blocks, which it is not.

5e8544685d IpSec Invalidate the Resource IDs on close()
To facilitate error checking we should invalidate
the resource IDs of all objects when we close() them.
Today, the resource ID is invalidated on the Transform
object but not on the SPI or Encap Socket. This CL

Chenbo Feng
aa7ba31c8e Use NetworkStatsService to get stats for apps
Move the native implementation of TrafficStats to NetworkStatsService
and apps need to get the NetworkStatsService binder interface from
system_server in order to get the network usage stats since boot. This
implementation can hide the detail of retrieving network traffic
information from apps and the NetworkStatsService can choose which
methoed it use to get the data depending on the kernel version of the
device.

6855aeeea2 Convert IpSecService resources to use refcounting
This is part 2 of 2 of the refcounting refactor for IpSecService
resources.

Switched ManagedResources to use RefcountedResource structure for
managing reference counts and eventual cleanup. Further, resource arrays
and quota management have been aggregated into a UserRecord for better
isolation. UID access checking has been similarly moved into the
UserRecordTracker, and resourceId checking has been rolled into
RefcountedResourceArray's accessor methods.

systems in IpSecService.

RefcountedResource objects allow for management of acyclical dependency
trees, ensuring eventual cleanup when resources are no longer used. This
cleanup may be triggered by binder death or by explicit user action.

20e96c55d5 Use consistent naming for allocating SPI.
Throughout the IPsec code (API, system server, netd) we use "reserve"
SPI and "allocate" SPI interchangeably. This renames to use "allocate"
everywhere for self-consistency and consistency with the kernel
(ALLOCSPI).

In javadoc, I am leaving the word "reserve" in several places because it
is still an accurate description of how the method behaves.
