pgcrypto: Remove non-OpenSSL support

2021-11-05T13:06:59+00:00

pgcrypto had internal implementations of some encryption algorithms,
as an alternative to calling out to OpenSSL.  These were rarely used,
since most production installations are built with OpenSSL.  Moreover,
maintaining parallel code paths makes the code more complex and
difficult to maintain.

This patch removes these internal implementations.  Now, pgcrypto is
only built if OpenSSL support is configured.

I learned the hard way that

        #if UNDEFINED_1 == UNDEFINED_2
        #error "gcc is idiot"
        #endif

prints "gcc is idiot" ...

Affected are MD5/SHA1 in internal library, and also HMAC-MD5/HMAC-SHA1/
crypt-md5 which use them.  Blowfish is ok, also Rijndael on at
least x86.

Big thanks to Daniel Holtzman who send me a build log which
contained warning:

Yes, gcc is that helpful...

Please apply this.
