Define free() as the default dispose function for plugin classes.

Most plugin classes in xine define a dispose function simply to call free(),
but free() is ABI-compatible with our dispose functions, so add a macro
that allows to pass free() directly as dispose function.

It's an opt-in so that no extra conditional is needed, and plugin authors
won't forget about providing a dispose function (if they need to).
