The isLegacy field of Nsd metrics should indicate whether the
data was collected from the old backend or not. However, it is
currently only dependent on the ENABLE_PLATFORM_MDNS_BACKEND
compat change value, which is incorrect. This is because the
NsdService always uses the new backend since Android U,
regardless of the compat change value. Therefore, the isLegacy
data should be obtained from each transaction.

This sets up what is necessary for an instrumented
ConnectivityService to run. Users of this class are
meant to inherit CSTest.

This is still relatively basic and does not have all the
instrumentation in ConnectivityServiceTest. Developers
looking to extend CSTest may find some instrumentation
missing ; when they add the missing instrumentation,
they should consider whether it should be generic for all
CSTests (and put it in base/), or whether it's local to
their own test suite. This should enable faster testing
as each CSTest children will only need to set up the
instrumentation it actually needs.

This patch also migrates a basic test to have a first user.

ot-daemon is a dependency of the new Thread feature. This commit
add the ot-daemon binary and init rc file to the Tethering module.
Note that the ot-daemon service is default disabled and versioned
init rc file is used to ensure that this service won't be started
before Android U.

This is expected to increase the size of "com.android.tethering.capex"
by around 400 KB.

Manual verification:
1. on Android T (33) CF device, the ot-daemon service is not started
   after device boots; It reports service not found error when trying
   to start the ot-daemon service with adb shell command "start
   ot-daemon"
2. on Android U (34) CF device, the ot-daemon service is not started
   after device boots; It can be started with shell comamnd "start
   ot-daemon" but then failed because of missing sepolicy rules as
   expected

Test: see above manual verification note

Due to try_make_writable's implementation:

  // try to make the 1st 'len' header bytes r/w via DPA
  void try_make_writable(struct __sk_buff* skb, int len) {
    if (len > skb->len) len = skb->len;
    if (skb->data_end - skb->data < len) bpf_skb_pull_data(skb, len);
  }

This *should* normally result in nothing actually being done.

This is because the 'len' we request should trivially be <= skb->len
(by virtue of how we construct the packet / get here),
and because skb->data_end - skb->data < len was previously
(to this patch) already checked below in line 251
(and thus the packet would have been dropped if it was false).

However, there's a tentative theory that we could somehow end up
with the entire payload in the non-linear portion of the packet,
and thus need to move it into the linear header portion where
we actually have direct packet access to it.

Note also that we already called this in line 71, so it should
be safe to add another call without causing bpf verifier unhappiness...
