Add an explicit list of options that can be disabled, enabled, ...

Configure has, so far, had no control at all of which 'no-' options it
can be given.  This means that, for example, someone could configure
with something absurd like 'no-stack' and then watch the build crumble
to dust...  or file a bug report.

This introduces some sanity into the possible choices.

The added list comes from looking for the explicit ones used in
Configure, and from grepping after OPENSSL_NO_ in all source files.
