There may be additional CapabilitiesChanged callbacks before

Ikev2VpnTest uses TestNetworkRunnable to start test networks
to perform VPN related tests. In some low performance devices,
such as cuttlefish, the request to disconnect test network
at the end of the previous test may not be executed completely
yet. It results in the disconnect-pending network being used
by the follow-up test and fail the test. To fix this, the utility
method should wait for onLost callback before performing next
test.

This test is run by resolver MTS and it should pre-check device
connectivity before running. The reason why the test never or
seldom failed in the past is probably that it usually ran after
CtsNetTestCasesLatestSdk DnsResolverTest (which is also run by
resolver MTS) that already pre-checked the connectivity.

Add end-to-end testing for conflicts happening during and after probing.

This includes making sure that interfaces have a usable IPv6 address
before starting each test, as mdnsresponder would not probe on the
interface if the address is not present, and would go straight to
advertising otherwise.

This patch is based on aosp/2535559 from maze@.

Add source prefix into the upstream key such that only packets which
source IPv6 address matches it will be forwarded to the upstream
interface.

In this patch, the source prefix is set to zero so there is no
behavior changes. Next CL in patch series will use the real source
prefixes retrieved from upstream interface.

NativeHandles shouldn't be closed in OffloadHardwareInterface after
passing them to initOffload() of AIDL service, because their owner
will be changed to ParcelFileDescriptor by libbinder.

Add test cases to verify that NativeHandles are closed correctly.
NativeHandles should be closed after initOffload if:
  - Init with HIDL HAL interface
  - Has null NativeHandle, any non-null NativeHandles should be closed

The NsdService will throw a NPE if a new client is registered
with a null INsdManagerCallback object. To avoid this, perform
a null check before registering a new client and throw an
IllegalArgumentException if the callback is null.
