Boy, you want this feature, don't you?  :)

I would rather make it another member of the ao_info struct, but that would
break the current client apps. In order to not break backward compatibility
with the current library API, I will do this by adding an ao_get_extension()
to the library and an ao_plugin_get_extension() to the plugin API (which
*will* break that API, but I don't care since I can change all the plugins
anyway).

[Aside: Adding members to a C struct destroys backward compatibility,
right?  That sounds obvious, but I just want to check.]
