Use SecureRandom instead of Random since Random is time based and can
increase the chance of generating same MAC address across multiple
devices.
createRandomUnicastAddress should randomize all bits of the address,
except for locally assigned bit and unicast bit. The previous method
that only randomizes NIC and use Google Base OUI is renamed to
createRandomUnicastAddressWithGoogleBase.

When switching from a validated default network to a new validated
default network (typically because of a better score),
DefaultNetworkMetrics would not reset the last validation timestamp.
This would cause the new default network to have a total recorded
validation time overcounted by the validation time of the previous
default network.
The following fix should be applied downstream for consumers of
previously recorded data:
validation_time = min validation_time, duration_time);

The shutdown method in NetworkManagementServiceTest was trying to close
the local socket on the test side, causing the NativeDaemonConnector
internal to NetworkManagementService to sometime crash due to the
output stream on NetworkManagementService side to throw on pending
reads.
The correct fix would be to shutdown the NativeDaemonConnector
inside NetworkManagementService and implement NetworkManagementService's
shutdown method, however there is no way to cleanly close a
NativeDaemonConnector.
Instead, this patch doesn't do any cleanup of the listening socket, the
test local socket, and its output stream. These objects' resources get
eventually collected by the system when the test process exits.

This change adds one KernelResourceRecord type (TunnelInterfaceRecord),
and adds methods for the creation of TunnelInterfaces, as well as the
application of Transforms to the given TunnelInterfaces
As part of the generation of ikeys/okeys, a ReserveKeyTracker manages a
java bitset to avoid collisions and reserve/release keys.

Add a test for new UID checking code.
Remove UID_RANGES_ADDED and REMOVED.
Move VPN allowed UIDs into NetworkCapabilities.
Pre-import to remove a conflict.

If the qtaguid proc file is no longer exist, the device is running new
eBPF module to do traffic accounting. So the NetworkStatsFactory need to
use the proc/net/dev interface to get the per interface traffic stats
summary. Also, adding a test to verify the helper function work properly

Add the native method used to read the detail information of network
stats from bpf maps. The native method of NetworkStatsFactory should
choose the correct implementation to get the stats detail depending on
the kernel version. Currently the bpf result is printed as a reference
and the actual behavior of NetworkStatsFactory should not change.
Test: NetworkStatsFactory related cts test should not fail.

CreateTransportModeTransform and DeleteTransportModeTransform are both
agnostic as far as which mode of transform it creates/deletes. As such,
to facilitate the implementation of tunnel mode, this patch renames them
to CreateTransform and DeleteTransform, along with all test names.

* changes:
Track and persist in stats whether traffic is on the default network.
Add the default network to NetworkStats and NetworkStatsCollection.
Pass all default networks to NetworkStatsService
This change adds the defaultNetwork to the ident based on current
system networking state, and persists that value to flash.

Change-Id: Id8776d149b2977548a9eb455ad4926af55e25aba
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.
