Rework objects extension to have "value ports" and "message ports".
Make audio and control buffers in ingen actually object buffers (towards interop). Overhaul the hell out of ingen buffer and mixing stuff. git-svn-id: http://svn.drobilla.net/lad/trunk/ingen@2266 a436a847-0d15-0410-975c-d299462d15a1
