When strict SCT fails record verification failure

Since with SSL_VERIFY_NONE, the connection may continue and the
session may even be cached, we should save some evidence that the
chain was not sufficiently verified and would have been rejected
with SSL_VERIFY_PEER.  To that end when a CT callback returs failure
we set the verify result to X509_V_ERR_NO_VALID_SCTS.

Note: We only run the CT callback in the first place if the verify

data records. The logic in the while loop which reads in each record is
supposed to only continue looping if the last record we read was app data

was actually checking that the first record had app data and we have an
app data record waiting. This actually amounts to the same thing so wasn't
wrong - but it looks a bit odd because it uses the |rr| array without an

there is only ever one read buffer. This reverts that change. In practice
