DEFINE_STACK_OF(EVP_MD) seems to have gone; recreate it. And quell a warning.

+1 on this release.

Add author files in accodance to governance, etc.

Some algoritms, such as 'X9.42 DH' have a space in them (full list with < openssl list -public-key-algorithms >). So we need to be slightly more careful with tokenizing - and thus vall back of ARGV which understands ticks and double quoted text.

Move clear-error (as a non-existent algoritm does not actually set an error - so we get confusing cruft if it is not cleared.

Add the autoconf generated files back in; as it breaks
builds in way to many ways.

Allow installtime redirection of libexec (for the modules) and the incude files that differs from the APXS
location (where the rest of the modules and include live. This lets us work with the NixOS buuld and
package system that keeps thse religiously separate.

Also remove the generated files - autoconf/automake will regenerate them.
