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.

We missed this one because rc5 is disabled by default.

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).

Also, move all the internal EVP_CIPHER building macros from evp_locl.h

EVP_CIPHER_CTX_flags was returning the flags of its associated
EVP_CIPHER.  However, EVP_CIPHER_CTX has flags of its own, so this
function is quite confusing and therefore error prone.

Note: there's a larger number of implementations in crypto/evp/ that

New functions:

- EVP_CIPHER_CTX_encrypting()
- EVP_CIPHER_CTX_iv()
- EVP_CIPHER_CTX_iv_noconst()
- EVP_CIPHER_CTX_original_iv()
- EVP_CIPHER_CTX_buf_noconst()
- EVP_CIPHER_CTX_num()
- EVP_CIPHER_CTX_set_num()
- EVP_CIPHER_CTX_cipher_data()
- EVP_CIPHER_CTX_new_cipher_data()

Note that the accessors / writers for iv, buf and num may go away, as
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).

Following the method used for EVP_MD_CTX and HMAC_CTX,
EVP_CIPHER_CTX_init and EVP_CIPHER_CTX_cleanup are joined together
into one function, EVP_CIPHER_CTX_reset, with EVP_CIPHER_CTX_init kept
as an alias.
EVP_CIPHER_CTX_cleanup fills no purpose of its own any more and is
therefore removed.

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).

It was assumed that a dummy with the type PRIVATE_PROCEDURE would
simply occupy a slot but otherwise ignore the symbol.  Not so, but
there is SPARE for that purpose.
