Change all calls to getenv() inside libcrypto to use a new wrapper function
that use secure_getenv() if available and an issetugid then getenv if not.
CPU processor override flags are unchanged.
Extra checks for OPENSSL_issetugid() have been removed in favour of the
safe getenv.

(cherry picked from commit 5c39a55d04)
Move the call to ct_base64_decode(), which allocates, until after
the check for NULL output parameter.
Also place a cap on the number of padding characters used to decrement
the output length -- any more than two '='s is not permitted in a
well-formed base64 text. Prior to this change, ct_base64_decode() would
return a length of -1 along with allocated storage for an input of
"====".

On error, i2o_SCT_signature() and i2o_SCT() free a pointer that may
have wandered off from the start of the allocated block (not currently
true for i2o_SCT_signature(), but has that potential as the code may
change. To avoid this, save away the start of the allocated block and
free that instead.
Thanks to Guido Vranken for reporting this issue.

Previously, if ct_v1_log_id_from_pkey failed, public_key would be freed by
CTLOG_free at the end of the function, and then again by the caller (who
would assume ownership was not transferred when CTLOG_new returned NULL).

SCT_verify is impossible to call through the public API (SCT_CTX_new() is
not part of the public API), so rename it to SCT_CTX_verify and move it
out of the public API.
SCT_verify_v1 is redundant, since SCT_validate does the same verification
(by calling SCT_verify) and more. The API is less confusing with a single
verification function (SCT_validate).

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.
