Dago has recently asked me about restoring this symlink.  It's
certainly technically possible, but let me ask this question:

This symlink, if I understand correctly, makes it impossible to have
multiple MySQL databases installed at the same time, because
/opt/csw/lib/mysql is "the MySQL database", which is something people
were arguing against (notably, Phil).

If the presence of MySQL libraries in /opt/csw/lib/mysql is necessary,
why not install MySQL with to the common /opt/csw prefix instead?

Either we have one default version of MySQL or we don't.  If we don't,
the symlink shall not exist.  If we do, let's install one MySQL
version into /opt/csw, and alternative versions (e.g. 4) to private
prefixes.

Thoughts?
