audio/filter: use new option API 

Make the VF/VO/AO option parser available to audio filters. No audio
filter uses this yet, but it's still a quite intrusive change.

In particular, the commands for manipulating filters at runtime
completely change. We delete the old code, and use the same
infrastructure as for video filters. (This forces complete
reinitialization of the filter chain, which hopefully isn't a problem
for any use cases. The old code forced reinitialization too, but it
could potentially allow a filter to cache things; e.g. consider loaded
ladspa plugins and such.)

Remove all filters. Note that like the other sub-commands, this does
not control automatically inserted filters.
You can assign labels to filter by prefixing them with ``@name:`` (where
``name`` is a user-chosen arbitrary identifier). Labels can be used to
refer to filters by name in all of the filter chain modification commands.
