9f668ceed2 AU: fix optional buffers 
The spec [1] says:
 "If the mData pointers are null, the audio unit can
  provide pointers to its own buffers. In this case,
  the audio unit must keep those buffers valid for
  the duration of the calling thread’s I/O cycle."

A plugin *can* do this, but it does not need to. An extra
NULL test is required.

furthermore [2] specifies

 "mDataByteSize -  The number of bytes in the buffer pointed
  at by the mData field."

In case the host does not provide any buffers, this is obviously zero.

7afb068fa6 When muting MIDI, silence all playing notes 
All-note-off event (CC 123) needs to be accompanied
with raising the sustain-pedal (CC 64).

cd6e074e92 Fix MIDI velocity scale for muted sends and manual faders 
Do not send continuous stream of note-evens with zero velocity
after muting a MIDI track or after a fade to silence completed
(and all-notes-off has been sent).

NB. Automated Faders are left untouched (no panic is sent for -infdB gain),
Note-on events with zero velocity are sent.

33c251a623 Fix MSVC compilation 
This resolves a circular dependency:
libardour calls methods from libardour_cp and vice versa.
Since 9bb2f2bb libardour is also calling active() and that method
needs to be forced to use late binding. -- compare to b9bbea7174

USB stack may not be available on some systems, e.g. unit-test VM.
When libusb_init(0) fails to create default context, further calls
into the libusb API will cause segfaults.

772444d769 Unit-test update: honor FadeInAutomation parameter-range 
Since 3d15499cda, libevoral enforces Parameter min/max
range. Ardour::ParameterDescriptor sets FadeInAutomation range to 0..2.
Hence all unit-test data needs to be in this range.

9bb2f2bb69 Prevent duplicate Ctrl-protocol instances 
ControlProtocols are single instance.

Activating an already active protocol leads to crashes due to
various rasons (e.g. port already registered), re-used singleton
event_loop_name and request-buffers, duplicate free of
AbstractUI request buffers during deactivate,..

4949f9a0b3 Reset write-source only when necessary 
When I/O port-counts do not change, plugin re-order happens
in sync in the process-thread. ::configure_io() is only called
to ensure that the current configuration is valid.

In case that the ChanCount does not change, the method must
be realtime-safe and not block.

DiskWriter::reset_write_sources() is not realtime-safe and
implicitly causes a session-save:

Write-sources are destroyed and re-created. This includes
a call to write_source->drop_references(), which triggers
ARDOUR::Session::remove_source(), which saves the session.

Furthermore adding/removing plugins will likewise call
::configure_io().

Previously any processor change on a track lead to
saving the session!
