Partial support for message/value ports and the message context.

This use case now works:
 - Add an event input and the "print" plugin from imum.lv2 to ingen
 - Connect the event input to the input of "print"
 - Hook Ingen up to JACK and play some MIDI events
   (or get events to the print plugin from anywhere else)
 - The "print" plugin will print the received events to the console
   in the message context (i.e. the audio thread is realtime safe)
