Test: new tests in ConnectivityServiceTest added in previous CL
Change-Id: Iec22ff636de0c02193576fe2e2d36b8bc7380457
Currently, when an always-on VPN is set in lockdown mode, Vpn
configures prohibit UID rules in netd directly and does not
inform ConnectivityService of the fact.
This means that ConnectivityService cannot send NetworkCallbacks
that tells apps that they are blocked or unblocked. It also means
that ConnectivityService has to take the mVpns lock and call into
Vpn to allow synchronous APIs such as getActiveNetwork to return
BLOCKED if the app is blocked.
Move all this to ConnectivityService:
- Add a setRequireVpnForUids API to ConnectivityManager, and have
that pass the routing rules to netd.
- Update VpnTest to expect calls to ConnectivityManager instead
of to netd.
- Whenever setRequireVpnForUids is called, ensure that
ConnectivityService sends onBlockedStatusChanged to the
affected callbacks.
- Update existing unit tests to check for callbacks.
- Add a way to find the VPN that applies to a given UID without
taking the VPN lock, by instead scanning all connected VPNs.
Use this as a replacement for direct access to mVpns.
For simplicity, and in order to ensure proper ordering between
the NetworkCallbacks sent for VPNs connecting and disconnecting,
process blocked UID ranges on the handler thread. This means that
when setRequireVpnForUids returns, the rule changes might not
have been applied. This shouldn't impact apps using network
connectivity, but it might mean that apps setting an always-on
package, and then immediately checking whether networking is
blocked, will see a behaviour change.

In order to support ConnectivityService mainline, module should
not use hidden APIs. The logic to get mobile provision is moved
to telephony surface since it's only used by telephony.
Hence, remove the design out from Connectivity.

Use two oneway binder interfaces instead.
The interfaces post messages to handlers as was implemented before, but
provide a more strictly defined interface, with less hops between
NetworkAgent, AsyncChannel, and ConnectivityService.
The actual public interface is the NetworkAgent @SystemApi: the binder
interface is an internal implementation detail.

Allow ConnectivityServiceTest to change the UID by replacing
static calls to Binder.getCallingUid() with a method that can
be mocked.
Add registerNetworkCallbackAsUid as an initial way to exercise
this, and add some test coverage to the always-on lockdown test
to confirm that things are working as expected.

Test: new unit tests
Change-Id: Ie0b32460e20e5906a0f479191e11a062f21cc608
This requires mocking lots of new things that weren't mocked
before but is otherwise fairly straightforward.
A few changes to MockVpn are needed as well:
1. Set the VPN's NetworkInfo to CONNECTED, so methods such as
isBlockingUid will work. While I'm at it, set the interface on
the LinkProperties as well to make things a bit more
realistic.
2. Constructs the VpnConfig when registering the agent, not when
the MockVpn is created. This is needed because starting and
stopping lockdown VPN calls prepare, which nulls out mConfig.
But constructing the VpnConfig when registering the agent is
more realistic anyway. The production code does that in
establish, but we can't do that in ConnectivityServiceTest
because some of the test cases don't call establish and call
registerAgent directly.

getActiveNetworkQuotaInfo has never been in API surface since it

Instead of statically linking against and jarjaring
TcpKeepalivePacketData, use the new android.net.TcpKeepalivePacketData
API for S. On R, build the KeepalivePacketDataParcelable from the base
KeepalivePacketData class.
The current ClientModeImpl code that uses a statically linked
TcpKeepalivePacketData is actually broken, as since R the system_server
has been sending a @hide android.net.TcpKeepalivePacketData, and
ClientModeImpl was testing it against com.android.wifi.x.android.net.*.
To fix this on R, this change rebuilds a
TcpKeepalivePacketDataParcelable class from the packet data included in
the base KeepalivePacketData class.
