Remove ECDH(E) ciphers from SSLv3

SSLv3 does not support TLS extensions, and thus, cannot provide any
curves for ECDH(E). With the removal of the default (all) list of curves
being used for connections that didn't provide any curves, ECDHE is no
longer possible.

Allow an ALPN callback to pretend to not exist

RFC 7301 mandates that the server SHALL respond with a fatal
"no_application_protocol" alert when there is no overlap between
the client's supplied list and the server's list of supported protocols.
In commit 062178678f5374b09f00d70796f6e692e8775aca we changed from
ignoring non-success returns from the supplied alpn_select_cb() to
treating such non-success returns as indicative of non-overlap and
sending the fatal alert.

In effect, this is using the presence of an alpn_select_cb() as a proxy
to attempt to determine whether the application has configured a list
of supported protocols.  However, there may be cases in which an
application's architecture leads it to supply an alpn_select_cb() but
have that callback be configured to take no action on connections that
do not have ALPN configured; returning SSL_TLSEXT_ERR_NOACK from
the callback would be the natural way to do so.  Unfortunately, the
aforementioned behavior change also treated SSL_TLSEXT_ERR_NOACK as
indicative of no overlap and terminated the connection; this change
supplies special handling for SSL_TLSEXT_ERR_NOACK returns from the
callback.  In effect, it provides a way for a callback to obtain the
behavior that would have occurred if no callback was registered at
all, which was not possible prior to this change.

Fix decoding of ASN.1 LONG and ZLONG items

LONG and ZLONG items (which are OpenSSL private special cases of
ASN1_INTEGER) are encoded into DER with padding if the leading octet
has the high bit set, where the padding can be 0x00 (for positive
numbers) or 0xff (for negative ones).

When decoding DER to LONG or ZLONG, the padding wasn't taken in
account at all, which means that if the encoded size with padding
is one byte more than the size of long, decoding fails. This change
fixes that issue.

Rather use -out parameter than redirect stdout

On some platforms, setting stdout to binary mode isn't quite enough,
which makes the result unusable. With -out, we have better control.

VMS: throw away [.util]shareable_image_wrap.c.in and add replacement scripts

[.util]shareable_image_wrap.c.in was never useful because lib$spawn()

Instead, we introduce two scripts that create and destroy a temporary
environment where the local shareable images become available,
[.util]local_shlib.com and [.util]unlocal_shlib.com.

crypto/x86*cpuid.pl: move extended feature detection.

Exteneded feature flags were not pulled on AMD processors, as result
a number of extensions were effectively masked on Ryzen. Original fix
for x86_64cpuid.pl addressed this problem, but messed up processor
vendor detection. This fix moves extended feature detection past
basic feature detection where it belongs. 32-bit counterpart is
harmonized too.

Fix out-of-memory condition in conf

conf has the ability to expand variables in config files. Repeatedly doing
