6ed4472b63 Move connectivity AIDLs to android.net
java_sdk_libraries and apexes need to contain bootclasspath classes
under predefined packages. Tethering currently uses android.net, so make
sure all the connectivity bootclasspath classes are under android.net.

This avoids maintaining two packages for the tethering APEX, where
com.android.connectivity.aidl is only used by internal AIDL files.

03433057cb Public API for per-profile network preference.
This patch defines the API, but does not make it public
yet as there is no implementation yet.

dd75352682 [NS01] Add NetworkScore
As attested by numerous TODOs in the code, a new way of
representing network quality and policy is needed instead
of an int.

An int representing the quality of the network requires
all parties using it to know how all other parties are
using it, and implementation details about the decision
algorithm. For all intents and purposes, the selection
is left to individual network factories who try to
achieve a desired result while piecing together all
possible states of the system.

As the number of such cases and desires increases, this
becomes both intractable and unmaintainable. Indeed, at
this time in the codebase nobody can really predict exactly
how a given change in score will affect selection across
the board, and it is essentially impossible to figure out
the behavior of network selection by inspecting the code
because the moving parts are scattered throughout the
entire codebase.

Having an object encapsulating policy and quality values
will let us centralize the selection and make it again
possible to maintain without knowledge of all behaviors
of all network factories. It will also provide better
guarantees of respecting policy, and allow bugfixes that
were not possible before because they'd touch too many
parts of the code.

7992afdcc3 ConnectivityManager: Provide API's to include location sensitive info
Existing NetworkCallback users will get NetworkCapabilities with
location sensitive data removed (except for ownerUid which will be
added for existing apps for backwards compatibility). Apps
have to opt-in to receive location sensitive data.

Note: This was chosen because WifiInfo is the only TransportInfo tha
has location sensitive info & that was added only in Android 12. If we
choose to default to true, all existings apps retrieving
NetworkCapabilities for wifi networks will be blamed for location access
unnecessarily.

Changes:
i) Add a flag in NetworkCallback creation to retrieve
NetworkCapabilities with location sensitive info in their callback.
(More flags are being planned for NetworkCallback for throttling
callback frequency, etc)
ii) For NetworkCapabilities.getOwnerUid(), we will continue to send the
data for apps targeting older SDK (since this is an existing field and
the new flag defaults location sensitive data to off).

5784080f24 [FUI22] Support getAllNetworkStateSnapshot
Currently, ConnectivityService has getAllNetworkState but it is
not ideal to expose as system API since the plan is to get rid
of NetworkState. Thus, create a new one that returns
NetworkStateSnapshot to fulfill the needs.

Note the original getAllNetworkState cannot be deleted now since
it has @UnsupportedAppUsage annotation.

0dd4b6f512 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.

549e9acd92 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.

773d918ade Remove legacy network factories
Nothing on the system is using registerNetworkFactory,
unregisterNetworkFactory at the moment.

registerNetworkFactory, unregisterNetworkFactory are protected by
signature permissions, so could not be used by anything outside of the
system.

Remove the two methods and the underlying support for this legacy,
deprecated mechanism.

8f37b3f55b Move module sources to packages/Connectivity
Files that are planned to be part of the connectivity module are grouped
in packages/Connectivity, so they can be built separately and moved in
one operation with their history into packages/modules/Connectivity.

This places the files in the existing framework-connectivity-sources
filegroup instead of the current framework-core-sources filegroup. Both
are used the same way in framework-non-updatable-sources.
