Currently, there is no limtation for an app to request
data usage callback, which is dangerous if the app fire
hundreds of thousands requests and potientially this might
cause OOM if the apps don't free them.

Normally if an app calls requestNetwork with capabilities that it
does not have permission to request, it gets a SecurityException,
except if it requests NET_CAPABILITY_CBS, in which case the request
will not throw but the app will get an onUnavailable callback.
Make this codepath throw as well. This simplifies the code and makes
the app-visible behaviour more consistent (and consistent with what
happens in S and below). The reason the code was written this way is because the carrier privilege app should receive a callback if it
loses permission. But onUnavailable is also not the best callback to
send, since it is used very rarely and also releases the app's
request. It seems better to leave the request registered and send
onLost.

Since 3p apps are allowed to use restricted networks in S, they
should be allowed to request a restricted network reasonably.
Otherwise, the functionalities of 3p apps will break if they rely
on restricted networks. Thus, CS needs to allow 3p apps to
request restricted networks if 3p apps are in the allowed list.

setUnderlyingNetworks() is mainly for the NetworkAgents who hold
the NETWORK_FACTORY to set its underlying networks.
And the underlying networks are only visible and useful for the
caller of getNetworkCapabilities() or the receiver of
onCapabilitiesChanged() who hold one of NETWORK_FACTORY,
NETWORK_SETTINGS and MAINLINE_NETWORK_STACK permissions.
Otherwise, the underlying networks field will be cleard before
sending.

In some scenarios, Wi-Fi connectivity is disrupted after roam. If an application reacts to network errors by calling reportNetworkConnectivity(false), validation will immediately fail and the device will switch to cell data.

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.
