 DBD::Sybase

-Returns true if we have an open (and working) database connection, false if it
-is not (yet) open (or does not work). (Executes a simple SELECT to make sure it
-works.)
-
-The reason this is needed is that L<DBD::Sybase>'s ping() does not work with an
-active statement handle, leading to masked database errors.
