This change introduces a limited library for dependencies on
framework-connectivity from Tethering,
connectivity-internal-api-util, where all classes are annotated with
@RequiresApi(S) to ensure proper API checks are done before usage.

  Add MdnsAnnouncer
  Also use other compressed names in DNS compression

MdnsAnnouncer is a implementations of MdnsPacketRepeater, which sends a
packet at various intervals.

It will be used to send initial advertisements when a service is
registered or there is a network change.

The previous implementation of writeLabels would not include a
compressed name in the label dictionary, so if a packet had
"something.local", "a.service.local" and "b.service.local",
"service.local" would not be compressed because "a.service.local"
already used compression (for .local).

Fix this and add a test.

(I'm guessing any remaining uses are in Java not C/C++?)

I'd like to remove the definition from the
  frameworks/libs/net/common/native/bpf_headers/include/bpf/BpfUtils.h
header file, where it really doesn't fit.

The testBlockedStatusCallback will get the default network,
and use it to verify upcoming callbacks. However, sometimes
the wifi network will be disconnected by previous executed
tests and becoming connected during the test, and fail the
test.

Thus, ensure wifi is the default network if it is supported
before testing.

Although RFC3845 2.1.1 specifies that NSEC records should not use
compression for the Next DomainName field, RFC6762 18.14 specifies that
compression should also be used for NSEC RDATA. The legacy mDNS
implementation does use compression for that field.

MdnsProber is an implementation of MdnsPacketRepeater that will be used
to send probes for service names before advertising them, to know if
they are already in use.

Targets that are part of builtin_deps will be removed / replaced by
gen_android_bp. So if such a target is encountered while parsing the gn
desc output, all of its dependencies can be safely ignored.

Add VpnTransportInfo.areLongLivedTcpConnectionsExpensive() in API
surface to allow privileged apps to know whether the long-lived
TCP connections should be expensive in the VPN network.

This is expected to be used combined with getBypassable()
because connections should always go through a VPN that is not
bypassable.
