bfd50cdeb0 rework MIDI [processor|plugin] chain 
* forward midi-data around plugins that have no MIDI-out
* allow to insert plugins with no MIDI-input at a point with one MIDI-channel

This works because excess ports (both plugin and route) remain
unconnected and use scratch-buffers.

Tested with LV2, LXVST and LADSPA.
(AU plugins with variable in/out retain the old behavior, no bypass)

4dc74ae2ea use zeroed scratch buffers for "silent" plugin runs 
Plugins rewrite the buffer data in-place and some plugins
can produce output even when fed with silence.

Hence, during a PluginInsert::silence() run a plugin can
inject data into the "silent" buffers which causes side-effects.

Kudos to Chris 'oofus' Goddard for finding this issue.

9b091a52cb clean up 44fc92c3 (not a threading issue but sigc++ problem)

00f26394a9 use dedicated buffers for route (and track) 
"scratch buffers are by definition scratch and their contents are undefined at all times"
"silent buffers are by definition all-zero and should not be used for real data"

But track & route were using those for actual data; plugins (which may run
in the same thread and may get the same buffers) use them for scratch thereby
overwriting real data.

In particular get_silent_buffers() (used by LadspaPlugin::connect_and_run)
clears the buffer which can holds real data:
e.g. via  Route::passthru_silence() -> plugin1 -> plugin2 (clears output of plugin1)
