This change includes:
  1. Refactor the logic in Tethering#dump into utils class.
  2. Move the utils class to a common place which could be referenced
     from other sub-modules.
  3. Add @MonitorThreadLeak annotation to enforce
     there is no thread leak problem.

FastDataInput for reading persistent data is currently disabled
by default. This functionality will be gradually enabled through
A/B experiments to assess its impact.

One-shot boot time increase up to 10 second is one expected
outcome in worst case. Currently, the persistent data was loaded
when the first caller query it, but in this change it will be
done twice in the boot stage due to the needs of doing comparison.

This implements a basic border routing test case (ping) and demonstrates a
valid test environment for Thread Border Router test cases.

Later we can add more packet verifications and more test cases.

This commit optimizes the mechanism to examine the TCP sockets
based on the VPN UID range.

The automaticOnOffKeepalives will be paused/resumed by checking
the TCP sockets status on the VPN network. The existing design
considers all UIDs, not the UID ranges for the specific VPN
network. This may lead to an inaccurate judgement to not to
stop the keepalive even when there is no socket on the VPN
network.

This commit is also a part of follow-up work from aosp/2354202
to use structized class to parse the TCP sockets.

`setTestNetworkAsUpstream` allows to specify a test network as the upstream of Thread network. This is going to be used in Thread integration tests. E.g. android.net.thread.BorderRoutingTest.

Currently, the MdnsReplySender doesn't have a dedicated test
class to verify its functionality. To address this gap, add the
MdnsReplySenderTest class, which can test all methods within the
MdnsReplySender class.

The test relies on the tethering module code. Test is supposed to run on the matching version of module prebuilt. Add mtcs tag to ensure this.

Add nlAttrs parameter to store the remaining attributes data.

As a part of follow-up work from aosp/2354202, the TCP socket
parsing can be done by using existing InetDiagMessage class.
The missing piece in the InetDiagMessage class is the possible
netlink attributes fields that may be appended after an
InetDiagMessage.

Ethernet interface naming is not consistent on Linux.
While some USB ethernet dongles show up as eth0,
others might show up as usb0.

This CL changes config_ethernet_iface_regex to "*" which stands
for "use Android version specific default". The default will
include both usb\d+ and eth%d named interfaces on Android V+.
Android T/U will continue to only include eth%d interfaces
(note that the "+" is a new addition which is highly unlikely
to have any actual effect, but is more technically correct).

This reverts commit ac6ff00b
with change of U+ to V+ minimum.

Reason for revert: Change from U+ to V+
