VMS: Fix internals test programs

The internals test programs access header files that aren't guarded by
the public __DECC_INCLUDE_PROLOGUE.H and __DECC_INCLUDE_EPILOGUE.H files,
and therefore have no idea what the naming convention is.  Therefore, we
need to specify that explicitely in the internals test programs, since
they aren't built with the same naming convention as the library they
belong with.

asn1/a_int.c: clean up asn1_get_int64.

Trouble was that integer negation wasn't producing *formally* correct

-(int64_t)u, but this triggers undefined behaviour for one value that
would still be representable in ASN.1. The trigger was masked with

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 util/mkdef.pl

The deprecation checking code here didn't work the same way as in
Configure, and used $config{options} to find an --api= option that
was never there.  This is replaced with checking $config{api}, which
is the controlling variable for deprecation.
