Given that ConnectivityService is moving to a mainline module, we need
a @SystemApi for it to listen for changes in blocked status of an uid.
So, we decided to create a new API for this which can provide
ConnectivityService with more info about why an uid is blocked (which
will be useful for adding a new similar onBlockedStatusChanged callback
in CM.NetworkCallback) and also captures data saver restriction without
having out to track it separately.

Currently, NPMS does some redundant computations because we are
calculating both uid rules and blocked reasons separately. In a
follow-up change, we will compute uid rules using blocked reasons
and later possibly remove that onUidRulesChanged callback.

ConnectivityManager will be a part of incoming connectivity
mainline. Settings will no longer to access the hidden methods.
For those methods that accept the interaction from users, they
should be exposed as formal interface to allow the
functionality. Expose them to API surface.

NetworkRequest is moving into the incoming connectivity mainline
module. The hidden setUids becomes inaccessible outside the
module. Shims for support cts in different API levels will need
to use it to verify the behavior of NetworkRequest. Thus, expose
it to the API surface.

Also, VPN uses getUids and setUids to control network
capabilities. Networkcapabilities is a part of incoming
connectivity mainline module but VPN is not. Thus, exposing these
two methods are needed to allow VPN to continue using it.

UidRange is used in a shared way between ConnectivityService
and VPN through the use of NetworkCapabilities. UidRange will
be part of the ConnectivityService mainline but Vpn.java will
stay in the framework. We need a way to replace the APIs using
UidRange, or to make UidRange system API. The only really
relevant surface here is NetworkCapabilities#{setUids, getUids}.
The need for UidRange could be replaced by an integer Range, so
replace the usage of UidRange by a integer Range in
NetworkCapabilities#{setUids, getUids} and update the relevant
callers.

ConnectivityManager and NetworkAgent do not share their handler with any
other component, so there is no reason to use addresses that do not
overlap. Protocol.BASE_* was written to allow for interaction "between
different StateMachine implementations without a conflict", but the
classes do not use StateMachine, and they do not have such interactions.

TCP_DEFAULT_INIT_RWND setting has never been set before, CS
always read the tcp receive window size from
net.tcp.default_init_rwnd then set to net.tcp_def_init_rwnd.
Thus, remove the unnecessary setting from CS, and the property
doesn't need to set either. Because aosp/1639922 migrate the
properties, the default value has been set to kernel already.

This is done by:
  1. In requestNetwork, provide a basic permission check.
  2. rematchNetworksAndRequests: no change, since non listen

  3. applyNetworkReassignment: no change, since non-request
