Needed because the BPF maps offloads IPv4 traffic. The kernel can't
trace the offloaded traffic to keep the conntrack entry.

The condition for deleting IPv4 forwarding rules.
1. When the tethering client has gone, deletes the client and its
rules.
2. When the upstream has gone, deletes all rules.
3. When the upstream has changed, deletes all rules.
Test: atest TetheringCoverageTests and check IPv4 offload rules
via dumpsys tethering in the following test cases.
Bug: 190783768
Test cases:
a. Loss upstream interface while tethering
1. Enable WIFI tethering
2. Disable upstream interface
3. Check the rules are removed.
b. Loss downstream interfaces while tethering
1. Enable WIFI tethering
2. Enable BT tethering
3. Disable BT tethering
4. Check the BT tether rules are removed.
5. Disable WIFI tethering
6. Check the WIFI tether rules are removed.
c. Switch upstream interface while tethering
1. Enable WIFI tethering
2. Enable BT tethering
3. Switch upstream interface from cellular to wifi.
4. Check all rules are removed.
d. Enable NAT failure (manual)
Log:
The rule deletion in each case.
- IpServer#stopIPv4: case b and case d.

Add tests for requestNetwork and registerNetworkCallback with
PendingIntents that are equal as per PendingIntent.intentFilterEquals.
In such situations, the first request is documented to be automatically
unregistered. This means that the PendingIntent should only be fired
once, instead of being fired for both requests.
Currently this behavior is broken for network callbacks (not for network
requests).

ConnectivityManager.setAvoidUnvalidated only works if the
config_networkAvoidBadWifi configuration is set to 0 and the
NETWORK_AVOID_BAD_WIFI setting is unset. There is no easy way
for a testing app to temporary set a test value to verify the
behavior of the API. Thus, add a mechanism to allow test app
to set a period of time to temporary unstrict the resource
configuration, i.e. Temporary simulate config_networkAvoidBadWifi
configured to 0.

To prevent making the duplication code in two places, move the

Many applications use ConnectivityManager without needing
TetheringManager (or without calling legacy ConnectivityManager methods
that delegate to TetheringManager), so initializing TetheringManager
when ConnectivityManager is created wastes resources.
This is especially true considering that TetheringManager is not trivial
to initialize (worst case scenario it starts a thread and does multiple
Binder requests), and ConnectivityManager is created in ActivityThread
when setting up the app proxy on startup.
