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
     requests will be automatically processed to track
     best satisfying network.
  3. applyNetworkReassignment: no change, since non-request
     will not be sent to factories.

NETWORK_STACK_UID check was introduced by aosp/1134635, and it
assumed that wifi factories/agents will be running on the network
stack process, but it didn't eventually. It runs in the system
server instead. So remove this check.

networkAttributes is a legacy configuration that is now only used to
configure which legacy type networks are supported, and what the restore
timer is for that network type, for the deprecated
startUsingNetworkFeature API.

Use a dedicated resource for the restore timers, and build supported
legacy network types using hasSystemFeature for wifi, wifi p2p,
bluetooth, proxy types, and TelephonyManager.isDataCapable for the
mobile types.
