This is useful for link layers that disconnect but know they will
reconnect to a similar network soon, and do not want the device
to switch to another network until the reconnect happens. An
example is wifi switching to another network that is on a
different subnet without the device switching to cellular data.
This works by immediately destroying the network, so the link
layer can reuse the same interface name for the new network. It
would be possible to delay destroying the network until the new
network connects, but in practice this does not seem useful,
because the if the link layer reuses the interface, then the
interface will be undergoing reconfiguration, and will likely
not be usable for app traffic.
This CL also moves the call to onNetworkDestroyed into
destroyNativeNetwork. This is needed to ensure that the new
API calls onNetworkDestroyed even though most teardown
operations have not happened. This causes onNetworkDestroyed to
happen before the netId is marked free, but that shouldn't cause
any behavioural changes because netId allocation is an
implementation detail of ConnectivityService and is not
observable by apps or system components.

Rate-limiting cannot work because the BPF program is in the
mainline version of netd.c, which is placed into net_shared

Disable it entirely to ensure no impact on S.

Most of the methods in BpfNetMaps are only used on T+ devices,
where BpfNetMaps never calls into netd. Remove the code in these
methods that calls into netd, because that code can never run.
The code was only written in the first place because it was
necessary when TrafficController had not yet moved to mainline.
The list of methods is:
- addNaughtyApp
- removeNaughtyApp
- addNiceApp
- removeNiceApp
- setChildChain
- replaceUidChain
- setUidRule

swapActiveStatsMap is temporary added for the NetworkStatsFactory to

NetworkStatsFactory already be mainlined, calling BpfNetMaps#swapActiveStatsMap

The tc police filter attaches to the clsact qdisc, so the rate limit
cannot be enabled before the qdisc is added to the interface.
The clsact qdisc is added as part of INetd#networkAddInterface, which is

The API won't modify the passed NetworkCapabilities and
LinkProperties, but redactNetworkCapabilitiesForPackage and
redactLinkPropertiesForPackage sound like they will. To reduce
the confusion, rename the API with prefix "getRedacted".
Also modify the javadoc to describe more about what the API will
do if the given UID doesn't have location permission.

This is being added as the lowest priority score factor, just
above the tie-breakers. It ensures that a network that has been
destroyed will lose to another identical network that has not
been destroyed, but will otherwise be scored identically.
The flag is a CS-managed flag that is stored in NetworkAgentInfo.
Currently it is always false, but it will be populated in
future CLs.

This makes the code easier to maintain because we do not need to
manually add string representations, and because it will throw at
static initialization time if the clas contains duplicate
POLICY_xxx values. The memory overhead is likely negligible.

Currently, there are two EVENT_NETWORK_TESTED message types in
ConnectivityService. One is used by the ConnectivityService
handler to process validation results, and one is used by
ConnectivityDiagnosticsHandler to send connectivity reports.
The two messages have different contents so it is confusing that
they have the same integer and the same name. Rename the second
one to CMD_SEND_CONNECTIVITY_REPORT.
