cd67529417 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.

bcd692fdc9 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.

a5a903d0b5 Stop using mVpns in getConnectionOwnerUid.
Use data that is already available in ConnectivityService
instead.

The behaviour of the new implementation is slightly different
from Q and R code when the permission check fails.

- The old code would throw a SecurityException if an app that
  was not an active VPN called the method, and would return
  INVALID_UID if the connection belonged to a UID that was not
  subject to the VPN.
- The new code returns INVALID_UID in both cases.

This does not seem like a compatibility problem. The only case in
which the code throws SecurityException is if the app is not a
current VPN app, but the app already knows whether it is or not.
The docs don't mention that the method SecurityException, either.

76b639e1bc 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.

Lorenzo Colitti
dd53c5889b Fix the legacy VPN tests that start racoon.
These tests do not actually work, or at least not as designed.
What happens when they are run is that creating/connecting the
VPN throws an exception. The call to legacyRunnerReady.block()
times out after 10 seconds because the condition variable is
never opened, but the doesn't notice the timeout becasue it
doesn't check the return value of block().

There are two reasons for the VPN not coming up.
1. VpnConfig.getIntentForStatusPanel calls into PendingIntent and
   ActivityManager statics, which bypass all the mocks and fail
   with an appops denial. Fix this by making it a dependency.
2. The tests are broken due to the UserManager API changes
   tracked in b/175883995. Fixing by adding a bit of ad-hoc code
   into startLegacyVpn, with a TODO to delete it once the rest of
   the UserManager setup code is fixed.

Fix these and check the return value of block(). This ensures
that if any other breakage is added the test will actually fail.
Also check that the throw route survives all the way to the
LinkProperties sent to the agent.

The score argument is going away, so there no longer
is a need to test it. It's never been used by anybody
and is actually a problem going forward.

Since removing the argument requires a small re-arch
of the testing tool anyway, rebuild expecting requests
on top of TrackRecord. This simplifies the test a
great deal, as well as (as observed in running the
tests) makes the test faster.

4484070163 Fix legacy APIs when VPN switches to suspended underlying network.
Currently, when the VPN underlying network changes from a
network that is not suspended to one that is suspended (or vice
versa), some of the legacy APIs return incorrect results.

This is because the VPN's NetworkInfo can get into SUSPENDED
state even though the capabilities have the NOT_SUSPENDED
capability. This happens because the code in updateCapabilities
that checks for changes in NOT_SUSPENDED and NOT_ROAMING (which
are the capabilities that can affect the NetworkInfo state) is
only run when the capabilities change in a certain way.

Fix this by always checking for changes in these capabilities,
regardless of what else has changed.

This results in sending a lot more SUSPENDED and RESUMED
callbacks than the code sent previously. This should hopefully
not impact apps because those callback methods have never been
public API, though because they're just callbacks, it's possible
that apps found out via code inspection that the callbacks
existed and implemented them.
