For some strange reason opensslconf.h was only defining DES_LONG
when included via des.h, but that's exceedingly fragile (as a
result of include guards the include via des.h might not actually
process the content again).

Ripped out the nesting constraint, now always define OSSL_DES_LONG
if not already defined.  Note, this could just be DES_LONG, but
trying to avoid exposing DES_LONG in places where it has never been
seen before, so it is up to des.h to actually define DES_LONG as
OSSL_DES_LONG.

It seems like the convention for VMS exit codes is to combine the VMS
C facility code (0x35a000) with a recoded exit code as follows:

    0     => 1
    1-255 => 8*code + 2

We also add 0x10000000, which is the control bit that has DCL not
report the error on the terminal.  That's just as well, since it would
be quite nonsensical, for example:

    %C-W-NOMSG, Message number 0035A018

We could do all this by using the normal exit() function after having
defined the macro _POSIX_EXIT.  Unfortunately, this feature only
exists in VMS C V7.1 and up.

VMS being a record oriented operating system, it's uncertain how the
'pipe' passes binary data from one process to another.  Experience
shows that we get in trouble, and it's probably due to the pipe in
itself being opened in text mode (variable length records).

It's safer to pass data via an intermediary file instead.

VMS uses a variant of openssl.cnf named openssl-vms.cnf.

There's a Perl on VMS mystery where a open pipe will not SIGPIPE when
the child process exits, which means that a loop sending "y\n" to it
will never stop.  Adding a counter helps fix this (set to 10, we know
that none of the CA.pl commands will require more).

those rather belong in the implementation's own structure (cipher_data)
when the implementation would affect them (that would be the case when
they are flagged EVP_CIPH_CUSTOM_IV or EVP_CIPH_FLAG_CUSTOM_CIPHER).

It was assumed that the syntax FOO/Foo=PROCEDURE would create both an
upper case and mixed case symbol in the GST.  Not so, it requires
having both FOO/Foo=PROCEDURE (to create the upper case alias) and
Foo=PROCEDURE (to create the mixed case slot).

We make sure that any symbol always occupies two slots (even those
that don't exist) by filling up with SPARE when necessary.  That will
assure that any changes will still have the same symbols in the same
slots no matter what (save a complete rewrite of the ordinals files).
