This adds the moved tests to CTS as well.
The moved unit tests are appropriate for CTS as they test data holder
classes that need to function properly for apps to work.

Change-Id: I603a0b0dfb67a942679a668c182aa650774c80b2
When a fully-routed VPN is running, we want to prevent normal apps
under the VPN from receiving packets originating from any local non-VPN
interfaces. This is achieved by using eBPF to create a per-UID input
interface whitelist and populate the whitelist such that all
non-bypassable apps under a VPN can only receive packets from the VPN's
TUN interface (and loopback implicitly)
This is the framework part of the change that build the whitelist.
The whitelist needs to be updated in the following cases:
* When a VPN is connected and disconnected
This will cover the change to allowBypass bit, since that can't be
changed without reconnecting.
* When a VPN's NetworkCapabilites is changed (whitelist/blacklist app changes)
* When a new app is installed
* When an existing app is removed
* When a VPN becomes fully-routed or is no longer fully-routed
New user/profile creation will automatically result in a whitelist app change
transition so it doesn't need to be handled specially here.
Due to the limitation of the kernel IPSec interacting with eBPF (sk_buf->ifindex
does not point to the virtual tunnel interface for kernel IPSec), the whitelist
will only apply to app VPNs but not legacy VPN connections, to prevent breaking
connectivity with kernel IPSec entirely.

Since socket keepalive APIs for UDP encapsulation sockets are
public to generic app. In order to ensure the given fd is valid,
this change verifies the resource id inside the UDP
encapsulation socket by using methods provided by IpSecService.

This change adds a new NATTKeepalive resource type, along with the
associated allocation/deallocation. Additionally, this change allows
ReferenceCountedResource(s) to not be binder-linked, to allow the
ConnectivityService to verify ownership and allocate a NattKeepalive
without double-registering for binder-death notifications.

Currntly, keepalive slot is released when stop() is called. Next
starting keepalive can use the same slot number while previous
keepalive is still stopping. When the previous keepalive is
stopped, the incoming as will be processed by the new keepalive.
This change release keepalive slot after the result of stopping
has returned. Thus, newly created keepalive cannot allocate the
same slot number while lower layer is still processing stop event.
This change also disable flaky assertions that are caused by
test port has been occupied by other process.

This patch fixes a bug where if a binder dies before the linkToDeath
call, the cleanup will be performed before the entry is added to the
array. While it is safe in that quotas and tracking performs as per
normal, the RefcountedRecord may not be cleaned up.
Rethrowing this exception is safe, since the only paths that would hit
this are all on binder threads coming from applications. Further, it
seems there is only one real way of this getting hit - if the app that
called the creation died during the binder call.
