Deprecate the function ASN1_STRING_data() and replace with a new function
ASN1_STRING_get0_data() which returns a constant pointer. Update library
to use new function.

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.

Pass entire CTLOG_STORE to SCT_print, rather than just the SCT's CTLOG
SCT_print now looks up the correct CT log for you.

Remove 'log' field from SCT and related accessors
In order to still have access to an SCT's CTLOG when calling SCT_print,
SSL_CTX_get0_ctlog_store has been added.
Improved documentation for some CT functions in openssl/ssl.h.

Some of the ASN.1 routines for the GeneralizedTime type can return
errors; check for these and do not continue past failure, so as
to appease coverity.

Use "!x" instead of "x <= 0", as these functions never return a negative
value.
