This is a partial revert of commit c8491de39 ("GH354: Memory leak fixes"),
which was cherry-picked from commit 55500ea7c in OpenSSL 1.1.
That commit introduced a change in behaviour which is a regression for
software implementing Microsoft Authenticode — which requires a PKCS#7
signature to be validated against explicit external data, even though
it's a non-detached signature with its own embedded data.
The is fixed differently in OpenSSL 1.1 by commit 6b2ebe433 ("Add
PKCS7_NO_DUAL_CONTENT flag"), but that approach isn't viable in the
1.0.2 stable branch, so just comment the offending check back out again.

Building for the Cygwin distro requires to be able to build debuginfo
files. This in turn requires to build object files without stripping.
The stripping is performed by the next step after building which creates

Previous commit f73c737c7 attempted to "fix" a problem with the way
SSL_shutdown() behaved whilst in mid-handshake. The original behaviour had
SSL_shutdown() return immediately having taken no action if called mid-
handshake with a return value of 1 (meaning everything was shutdown
successfully). In fact the shutdown has not been successful.
Commit f73c737c7 changed that to send a close_notify anyway and then
return. This seems to be causing some problems for some applications so
perhaps a better (much simpler) approach is revert to the previous
behaviour (no attempt at a shutdown), but return -1 (meaning the shutdown
was not successful).
This also fixes a bug where SSL_shutdown always returns 0 when shutdown
*very* early in the handshake (i.e. we are still using SSLv23_method).

Also in X509_verify_cert() avoid using "i" not only as a loop
counter, but also as a trust outcome and as an error ordinal.
Finally, make sure that all "goto end" jumps return an error, with
"end" renamed to "err" accordingly.
[ The 1.1.0 version of X509_verify_cert() is major rewrite,
which addresses these issues in a more systemic way. ]

During precomputation if the group given is well known then we memcpy a
well known precomputation. However we go the wrong label in the code and
don't store the data properly. Consequently if we call have_precompute_mult
the data isn't there and we return 0.

CVE-2016-0701 (fix part 2 or 2)
Issue reported by Antonio Sanso
Reviewed-by: Viktor Dukhovni <viktor@openssl.org>
Historically OpenSSL only ever generated DH parameters based on "safe"
primes. More recently (in version 1.0.2) support was provided for
generating X9.42 style parameter files such as those required for RFC
5114 support. The primes used in such files may not be "safe". Where an
application is using DH configured with parameters based on primes that
are not "safe" then an attacker could use this fact to find a peer's
private DH exponent. This attack requires that the attacker complete
multiple handshakes in which the peer uses the same DH exponent.
A simple mitigation is to ensure that y^q (mod p) == 1

Calling SSL_shutdown while in init previously gave a "1" response, meaning
everything was successfully closed down (even though it wasn't). Better is
to send our close_notify, but fail when trying to receive one.
The problem with doing a shutdown while in the middle of a handshake is
that once our close_notify is sent we shouldn't really do anything else
(including process handshake/CCS messages) until we've received a
close_notify back from the peer. However the peer might send a CCS before
acting on our close_notify - so we won't be able to read it because we're
not acting on CCS messages!
