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.

This is written based on observation that
  testStartVpnProfileNoPreviousConsent()
appears to result in the right things happening when running
  adb logcat | egrep --color -i 'Switched from |protect'
ie. it results in:
  I netd    : networkSetProtectDeny(<ctsappuid>) <0.01ms>
  I Vpn     : Switched from android.net.cts to [Legacy VPN]
  I netd    : networkSetProtectAllow(1000) <0.00ms>

Which disallows the CTS uid, and allows AID_SYSTEM.

That in turn appears to be the 'default' state of things.

So this basically copies that logic into tearDown()

aconfig soong modules should be used to read the trunk stable flag.
However they are not available in the mainline branch.
So this CL adds the method to check if the trunk stable flag is enabled
or not by directly reading from DeviceConfig.
It's expected that this does not work correctly if flag value is not
stored in the DeviceConfig.
But for the time being, this method can be used to keep development.
Once the mainline branch supports the aconfig soong modules, method
added by this CL must be removed and java_aconfig_library should be
used instead.

- Watches don't support VPN apps.
- The HostsideVpnTests CTS tests are already skipped on watches.
- The tests for VpnManager VPNs do run on watches, but there isn't
  actually a way to start a VpnManager VPN on a watch because there is
  no way to display the consent dialog to the user.
- The VpnService CTS tests verify the VpnService API on watches
  bypassing the consent dialogs.
- Because there is no way to start a VPN app on a watch, there's no
  point requiring the VPN CTS tests to pass.

This CL disables the remaining VPN CTS tests on watches. This allows
watches to disable the VPN service, reducing startup time and memory
usage.

Android's clat is for reaching the internet, which in general
never has an ipv4 L3 mtu higher than 1500.

(We could probably hit this on a jumboframe enabled IPv6-only

For the current code this is a no-op because the new
slots are always computed immediately in the same
critical section.

When the code uses callbacks for the carrier service UID
though, there will no longer be a time where the entire
array is reset. Instead, registering the callback will
immediately trigger the call that populates it again,
which means the value needs to be removed when a SIM
card is removed. Unregistering the callback is a good
time to do this.
