BPF needs upstream prefixes information to filter spoofing IPv6 source
addresses carried in downstream traffic.
We retrieve prefixes from upstream interface's LinkProperties and pass
it to the BpfCoordinator. Forwarding rules will also be updated when
upstream interface's IPv6 link addresses change.

This can make it easier to adopt SM shim replacement in follow up change,
as both SyncSM and AsyncSM will process the same message without any
difference.
This change also fix a problem that bring up downstream before it's
IpServer completely disabled.
Previous:
CMD_NOTIFY_PREFIX_CONFLICT -> requestEnableTethering(false) ->
requestEnableTethering(true) -> IpServer stopped ->
reportTetherStateChanged(downstream inactive) -> IpServer started
-> reportTetherStateChanged(downstream active)
New:
CMD_NOTIFY_PREFIX_CONFLICT -> requestEnableTethering(false) ->
IpServer stopped -> reportTetherStateChanged(downstream inactive)
-> requestEnableTethering(true) -> IpServer started
-> reportTetherStateChanged(downstream active)

When tethering restarts due to an IP conflict, it starts to
bring up downstream before its IpServer is completely disabled.

The problem is that the test releases mHotspotIpServer’s prefix before testing mUsbIpServer, which means that mUsbIpServer might choose the same address as mHotspotIpServer’s.
To fix this, we need to test that mUsbIpServer and mHotspotIpServer have different addresses before calling releaseDownstream(mHotspotIpServer).

A helper class to *read* java BpfMaps. This is designed to
provide direct bpf access in the caller process through
ConnectivityManager APIs.
The change also removes any statical link to
net-utils-device-common-struct from service-connectivity.
This is because net-utils-device-common-struct is already
included in framework-connectivity. Including it again in
service-connectivity would create a r8 build fail by circular
dependency.

There are only three calls to this method, and two of them
are with a list of 1 address which means it's simpler inlined.
The last call will be replaced with calls to RouteController
in a followup, meaning we addRoutesToLocalNetwork can be removed.

The created handler thread will stay there for a while until
all the tests are finished. This is considered as a leakage
which will take the resource from the devices. In low end
devices, this may possibly impact the performance. The created
threads should be closed explicitly.

Currently, metalava will discard concrete overrides of abstract methods
from the API signature files which causes problems when attempting to
generate stubs from those files and also discards information that may
be important in API reviews. This change is the first step in the
process of changing that behavior.
This change hard codes the current behavior for discarding the concrete
overrides (`add-additional-overrides=no`) into those signature files
that will (or are likely) to be affected by the change in behavior.
That allows the default behavior to be changed for all the other files
without affecting these.
Follow up changes will remove the hard coding from the signature files
and will update the contents which will include the concrete overrides
of the abstract methods.

go/add-overriding-one-pager.
