Code without PEDANTIC has intentional "undefined" behaviour. To get best
coverage for both PEDANTIC and non-PEDANTIC codepaths, run the sanitizer
builds in two different configurations:
1) Without PEDANTIC but with alignment checks disabled.
2) With PEDANTIC.

To not overload Travis too much, run one build with clang and the other
with gcc (chosen at random).

Also remove a micro-optimization in CAST code to be able to
-fsanitize=shift. Whether shift sanitization is meaningful for crypto or
an obstacle is debatable but since this appears to be the only offender,
we might as well keep the check for now.

As it turns out branch hints grew as kind of a misconception. In
addition their interpretation by GNU assembler is affected by
assembler flags and can end up with opposite meaning on different
processors. As we have to loose quite a lot on misinterprerations,
especially on newer processors, we just omit them altogether.

Suppress CT callbacks with aNULL or PSK ciphersuites that involve
no certificates.  Ditto when the certificate chain is validated via
DANE-TA(2) or DANE-EE(3) TLSA records.  Also skip SCT processing
when the chain is fails verification.

Move and consolidate CT callbacks from libcrypto to libssl.  We
also simplify the interface to SSL_{,CTX_}_enable_ct() which can
specify either a permissive mode that just collects information or
a strict mode that requires at least one valid SCT or else asks to
abort the connection.

Simplified SCT processing and options in s_client(1) which now has
just a simple pair of "-noct" vs. "-ct" options, the latter enables
the permissive callback so that we can complete the handshake and
report all relevant information.  When printing SCTs, print the
validation status if set and not valid.
