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
result is still X509_V_OK prior to start of the callback.

Move peer chain security checks into x509_vfy.c

A new X509_VERIFY_PARAM_set_auth_level() function sets the
authentication security level. For verification of SSL peers, this
is automatically set from the SSL security level. Otherwise, for
now, the authentication security level remains at (effectively) 0
by default.

The new "-auth_level" verify(1) option is available in all the
command-line tools that support the standard verify(1) options.

New verify(1) tests added to check enforcement of chain signature
and public key security levels. Also added new tests of enforcement
of the verify_depth limit.

Updated documentation.
