* changes:
  Simplify addRoutesToLocalNetwork calls
  Add LocalNetworkConfig
  Tell netd about local networks

This is a no-op change and refactors the design for subsequent
TTL expiration check changes.
- Add a ServiceExpiredCallback to notify expired services.
- To simplify the design, pass the CacheKey to MdnsServiceCache
  methods instead.

Override Vpn.setUnderlyingNetworks() to do a direct call on the

There are only three calls to this method, and two of them
are with a list of 1 address which means it's simpler inlined.

The last call will be replaced with calls to RouteController
in a followup, meaning we addRoutesToLocalNetwork can be removed.

This doesn't do anything at this patchset, but the whole
pipe from the agent to ConnectivityService is built.

LocalNetworkInfo will be the name of the public information
sent in callbacks to clients.

Test: CSLocalAgentTests
Change-Id: I70e133031ef3b0aaf6c3e59ccc2ad895c66d339c

This patch does the following :
• When a network is local but the system doesn't support it,
  throw in registerNetworkAgent.
• When a network is local, tell netd about it.
• Add tests for the above, as well as a test for callbacks
  being sent correctly when the caps are set and not when
  they aren't and that the new keep connected flag is
  respected.

Telling netd about the network being local has it add two
routes that do not exist if the network is not local :
• One at PRIORITY_LOCAL_NETWORK matching unmarked sockets
  and looking up the table for the interface.
20000: from all fwmark 0x0/0x10000 lookup xxxx
• One at PRIORITY_EXPLICIT_NETWORK matching explicitly on
  network 99, so that dnsmasq traffic and any OEM traffic
  marked for network 99 flowing there.
16000: from all fwmark 0x10063/0x1ffff iif lo lookup xxxx
IMPLICIT_NETWORK and EXPLICIT_NETWORK rules are installed
by connectivity service as a matter of course whether the
network is local or not.

See commit If8729fc6f3716a580c936584b851bc38000b5de5 for
implementation details of this mechanic.

There is no need to implement anything in particular for the
new connected reason, as the current implementation will
already keep it connected. A new test makes sure of that.

  Make variables in testLegacyLockdownVpn() final.
  Update testLegacyLockdownVpn to mock VPN.

This change adds overriding methods that are essential to compile the

Ethernet interface naming is not consistent on Linux. While some USB
ethernet dongles show up as eth0, others might show up as usb0.

This CL changes config_ethernet_iface_regex to "*" which stands for "use
Android version specific default". The default will include both usb\d+
and eth%d named interfaces on Android U+. Android T will continue to
only include eth%d interfaces (note that the "+" is a new addition which
is highly unlikely to have any actual effect, but is more technically
correct).

* changes:
  Add hidden constants for communicating about local network agents
  Use isAtLeast* from deps

When a network preference is set, the highest priority nri will
be a managed default request that disallows default networking.
In the case where there is no satisfying network,
mNoServiceNetwork is used as the satisfier instead of null.
(see computeNetworkReassignment)

mNoServiceNetwork should not be returned in any public API.
Check for the nri being satisfied before returning the satisfier
to ensure mNoServiceNetwork is not returned.

Add a test for lockdown vpn that uses TYPE_IKEV2_IPSEC_PSK and
mocks platform VPN by override in startLegacyVpnPrivileged().
In the context of ConnectivityService, setVpnDefaultForUids()
is the main interaction.

Refactor testLegacyLockdownVpn to take a VpnProfile and assert
behaviors with and without setVpnDefaultForUids().
This includes:
    1. Updating callback asserts and assertActiveNetworkInfo to
       reflect setVpnDefaultForUids().
    2. Adding TODOs where mCm.getActiveNetworkInfo() returns
       unexpected values.

The created handler thread will stay there for a while until
all the tests are finished. This is considered as a leakage
which will take the resource from the devices. In low end
devices, this may possibly impact the performance. The created
threads should be closed explicitly.

* changes:
  Prepare exposing Network{Request,Caps}.forbiddenCapabilities
  Add a keep connected for test reason
  Improvements to CSTest : legacy type, wait for LOST, permissions

* changes:
  Remove the fail case on IPv6 in testLockdownVpn
  Remove LockdownVpnTracker from testLegacyLockdownVpn

This is useful going forward in particular because there will
be a default forbidden capability for LOCAL_NETWORKS. This
means it will be useful to be able to remove it.

It is also generally useful and we have been wanting to open
this API to the public, so this is a good opportunity to do so.

Test: new tests for NetworkRequest
      NetworkCapabilitiesTest already has tests because it
      already was @SystemApi

This has been sorely needed for a while. Instead of filing requests
for each of your networks in a CSTest, which is fiddly at best and
sometimes almost impossible (because you can't single out the network),
you can now add this flag and be done with it.

• Make sure all Agents have a legacy type. This is necessary to
  avoid crashes in LegacyNetworkTracker
• Wait for LOST when disconnecting a network
• Make sure the test package sees its own permissions (importantly
  it can't see background networks otherwise, because it lacks
  CHANGE_NETWORKING_STATE)
