842075ed8e Move VPN code from ConnectivityService to VpnManagerService.
ConnectivityService itself does not depend on mVpns or the Vpn
class any more. Most of this CL is simply moving code from one
class to another:

- Move the AIDL calls from IConnectivityManager to IVpnManager.
- Move the implementation from ConnectivityService to
  the new VpnManagerService.
- Move the APIs from ConnectivityManager to VpnManager, but
  temporarily maintain some shims in ConnectivityManager for the
  moved calls so that existing callers do not have to be modified
  in this CL.
- Update VpnService to call IVpnManager instead of
  IConnectivityManager.
- Move the code that registers the VpnManager service from
  ConnectivityFrameworkInitializer to SystemServiceRegistry.

c71cff8837 Convert LockdownVpnTracker to NetworkCallbacks.
This will allow moving LockdownVpnTracker from the connectivity
to the VPN code. This requires moderate refactoring since it's
pretty tightly coupled to both.

In this CL:

1. Add an @hide API to tell ConnectivityService that legacy
   lockdown VPN is enabled. I chose not to use the existing
   setVpnRequiredForUids API because that method has specific
   semantics and because it will be required long term since
   it's used by non-legacy VPN types.

2. Instead of updating LockdownVpnTracker inline from the
   ConnectivityService handler thread, have it listen to
   NetworkCallbacks. This introduces an extra thread hop, but
   most of the interactions between the lockdown VPN and CS were
   via NetworkAgent, which is asynchronous anyway.

3. Add code to LegacyTypeTracker to send the extra
   CONNECTIVITY_ACTION broadcast for the underlying network type
   that is sent after the VPN connects. In order to do this, make
   Make LockdownVpnTracker specify its underlying network
   (via setUnderlyingNetworks) when it connects.

4. Reimplement LockdownVpnTracker#augmentNetworkInfo based on
   information that is available in ConnectivityService.

5. Remove the code in LockdownVpnTracker that counted errors.
   I think this code has not worked since lollipop, because
   ConnectivityService never sees NetworkInfo objects in state
   FAILED. This is because ConnectivityService only hears about
   NetworkInfo objects via NetworkAgents, and LegacyVpnRunner
   only registers its NetworkAgent when the connection succeeds.

a77d05ec0a Add a registerSystemDefaultNetworkCallback method.
This method allows internal components to track the system
default network. This differs from registerDefaultNetworkCallback
because that method sends callbacks for the default network for
the UID that called it. This may not be the system default
network, for example, when a VPN is up and applies to the UID.

7a0f31b944 More cleanly separate requests and listens.
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.

062b648099 [VCN07] Bypass VCN for non-internet app accessible cellular services
Deduce the NET_CAPABILITY_NOT_VCN_MANAGED capability from other
capabilities and user intention, which includes:
   1. For the requests that don't have anything besides
      VCN_SUPPORTED_CAPABILITIES, add the NOT_VCN_MANAGED to
      allow the callers automatically utilize VCN networks
      if available.
   2. For the requests that explicitly add or remove
      NOT_VCN_MANAGED,  do not alter them to allow user fire
      request that suits their need.
