Change all calls to low level digest routines in the library and
applications to use EVP. Add missing calls to HMAC_cleanup() and
don't assume HMAC_CTX can be copied using memcpy().

Note: this is almost identical to the patch submitted to openssl-dev
by Verdon Walker <VWalker@novell.com> except some redundant
EVP_add_digest_()/EVP_cleanup() calls were removed and some changes
made to avoid compiler warnings.

errors can be tolerated, hide the error from 'make'.
This gives shorter output both if ranlib fails and if
it works.

This compiles and runs on Linux, and external applications have no
problems with it.  The definite test will be to build this on VMS.

sure they are available in opensslconf.h, by giving them names starting
with "OPENSSL_" to avoid conflicts with other packages and by making
sure e_os2.h will cover all platform-specific cases together with
opensslconf.h.

I've checked fairly well that nothing breaks with this (apart from
external software that will adapt if they have used something like
NO_KRB5), but I can't guarantee it completely, so a review of this
change would be a good thing.

acceptable, since all that happens if it fails is a library with
an index, which makes linking slower, but still working correctly.

"Jan Mikkelsen" <janm@transactionsite.com> correctly states that the
OpenSSL header files have #include's and extern "C"'s in an incorrect
order.  Thusly fixed.

This was meant for building individual ciphers separately;
but nothing of this is maintained, it does not work
because we rely on central configuration by the Configure
utility with <openssl/opensslconf.h> etc., so the files
are only wasting space and time.
