Revert failed experiment, scripted multiple MIDI outputs via dsp_run()

This reverts commit 8702ff2189665b473918ed60f34b6be4010a06f7,
and b10d9cf09bf6150f0ba0eae5dc34fd8db8b2fa91.

There was a misconception on the iterator (port vs message
in sequence), besides Ardour's mixer-strip is preferably used
with a single MIDI port. Most plugin-standards also only support
one port.

If need be LuaDSP run_map() can be used to handle multiple
MIDI I/O ports already.
