* changes:
  Change ConnectivityServiceTest to prepare for VPN code move.
  Add to VpnManager the VPN APIs used by Settings and SystemUI.
  Remove temporary hack in VpnTest.

The static validate() method an PROXY_* constants in Proxy are
used by both module and Settings. After Proxy is moving into
connectivity module, Setting will not able to access them.
Thus, move them to ProxyUtils in net shared lib.

No-op changes to make it easier to review the VPN code move.
1. Set underlying networks via MockVpn, not ConnectivityService.
2. Add a processBroadcastForVpn utility method that we can modify
   without too much churn when the code is moved.

Settings and SystemUI use these through raw AIDL calls.
Make them proper manager calls so we can move the implementation
without touching the callers again.

For now these still call into ConnectivityService via
IConnectivityManager. In an upcoming CL the implementation will
move to VpnManagerService.

This temporary hack was necessary due to b/175883995. Now that
that bug is fixed, remove the hack.

Currently, NetworkRequest has several types of requests (LISTEN,
TRACK_DEFAULT, REQUEST, BACKGROUND_REQUEST), and we expect more
to be added.

There are really three categories of request:
1. Requests satisfied by only one network and will keep that
   network up, and thus need to be sent to NetworkProviders:
   REQUEST, BACKGROUND_REQUEST.
2. Requests satisfied by only one network but will not keep that
   network up: TRACK_DEFAULT
3. Requests satisfied by multiple networks and will not keep any
   networks up: LISTEN.

Unfortunately the separation is not very clear. Currently, for
any valid request, either isListen() will return true or
isRequest() will return true. This makes it impossible to tell
whether a particular request should be sent to NetworkProviders,
so the current code sends TRACK_DEFAULT requests to
NetworkProviders as well. This is incorrect - a TRACK_DEFAULT
should never keep a network up, for example.

This CL attempts to clarify things by making isRequest() return
false for TRACK_DEFAULT requests and thus never sending them to
NetworkProviders. After this CL:

- isRequest will return true only for requests that attempt to
  bring up or keep up a network.
- isListen will return true only for requests that match multiple
  networks but do not keep any of them up.
- Neither will return true for TRACK_DEFAULT.

* changes:
  Stubbed setOemNetworkPreference in Connectivity
  Update OemNetworkPreferences to use 1:1 Map

This is mainly used by VCN, where VCN-eligible networks might
be registered before VCN management service can fire request
to prevent the newly created network from being torndown
immediately by ConnectivityService.

...in order to be able to resolve IKE classes. Note that this can be
removed once the prebuilt stub in prebuilts/sdk contains IKE, which
can be achieved with a new import after this CL is submitted:
