Instead of passing state machine to UpstreamNetworkMonitor, wrapped it
by an interface would have two benefits:
1. Easier for testing.
2. Isolate state machine operation in callback.

TetherUpstream6Key#src64 should be stored in network order. Use
a big-endian ByteBuffer to retrieve a value stored in network order
is actually converts it into native order, which is little-endian in
Android.
In this CL, we changed it to use byte[] instead of long to store the
top 64-bits of the source prefix.

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.

As state transitions always occur after a message has been processed,
calling transitionTo only under processMessage makes the flow easier
to understand and less error-prone.
The risk of this change is very minimal since it is only about
handling the error, but tethering will stop regardless.

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).

Currently, Ipv6UpstreamRule is added follows the adding of
Ipv6DownstreamRule when it is the first rule from a downstream
interface to the upstream interface.
This CL changed it to:
1. Upstream interface change updates both IPv6 upstream and downstream
forwarding rules.
2. Neighbor events updates only IPv6 downstream forwarding rules.
Data limit setting on the upstream interface is now depend on the
upstream rules instead of the downstream rules. This CL also updates
corresponding test cases in IpServerTest and BpfCoordinatorTest.

In current code, IpServer will ensure bpf offload is supported before
calling BpfCoordinator's APIs. But those APIs already have the same
checks inside the function. This CL removed duplicated checks in
IpServer.
After this change, the BPF offload support status is only determined
inside BpfCoordinator and it won't change during the life cycle of
Tethering. Tethering initializes mBpfCoordinator just once in the
constructor. After that point, the value of isUsingBpf can never
change, because mIsBpfEnabled is final and
mBpfCoordinatorShim.isInitialized() is either always true (api30) or
can either never change (api31).
Also fixed a bug in IpServerTest upon this change.

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.

Different network objects with the same network ID should be
treated as the same network.
chooseUpstreamType compares the current upstream and new upstream
by object (comparison operator) instead of network id
(Network#equals). This implies that different objects with the
same network id still trigger upstream changed report.
Since this commit, reportUpstreamChanged is only called when upsteam
has really changed (connected, switched or disconnected) in
chooseUpstreamType. In previous code, reportUpstreamChanged is also
called if EVENT_ON_CAPABILITIES is called when the upstream is the
same but its capabilities changed.
The NotificationUpdater#onUpstreamCapabilitiesChanged method only
needs to be called by chooseUpstreamType when it chooses a new
upstream. If the upstream remains the same but its capabilities
change, the EVENT_ON_CAPABILITIES will call
onUpstreamCapabilitiesChanged.

This change store localOnly wifi clients in its own field so that

Currently, there are no tethered and localOnly hotspot clients at

When both SAP and LOHS are enabled, the SAP and LOHS clients from
TetheringEventCallback#onClientsChanged are all TETHERING_WIFI.

This commit adds two new fields, tx_bytes and rx_bytes, to the
UpstreamEvent message. These fields provide information about the
amount of data transferred during the event, which can be useful for
network performance analysis. The current tx/rx usages are always
zero, but it will be updated in a later change to reflect the actual
usage. No changes were made to the existing fields upstream_type and
duration_millis.
