[LAD] JACK CV Ports API

hey lads, sharing an idea I had here my (currently in development) host directly exposes plugin ports to jack - audio as audio, midi as midi, and parameters as a midi port for midi-cc usage. while coding for lv2 plugins, I noticed the CV port type, more info here: http://lv2plug.in/ns/ext/cv-port/ I didn't yet coded support for it, but I'll do soon. Those kind of ports will be exposed to jack as pure audio ports. Non-daw and non-mixer also use this kind of ports, and maybe others. The problem is that users shouldn't connect normal audio and CV ports together... so I came up with an idea that is simple and fairly easy to implement - a new jack port flag. example: port = jack_port_register(client, port_name, JACK_DEFAULT_AUDIO_TYPE, JackPortIsInput|JackPortIsCV, 0); patchbays can check for this flag and represent the port as a different type (I've done it here myself as jack keeps any custom port flag values I set, and works just fine). in the jack library code we can check for the flag and not allow port connections. what do you think?
