Replace missing .mid files with silence
This fixes a crash: missing playlist due to missing .mid,
and retains regions for missing MIDI files.

As opposed to missing Audio, we cannot use a SilentFileSource,
because MIDI files are destructive.

This also adds an API to query missing files that have been replaced
with silence to report them to the user.

LV2: disable unofficial LV2UI_Request_Parameter
This API is not official, and the upcoming official API differs.
The source-code is left in-place since most of it will be
re-usable as-is, regardless.

Fix seamless looping w/split-cycles
This fixes the following (loop-lennth > internal_playback_seek

---
Loop From: 3528000 To: 3880800  (len: 352800)

Fix cross-compile linking (arm-linux ld)
Explicitly specify required libraries (waf does no longer

M: Make edit_aux_send insensitive
Mixbus does not have a working aux-panner and also no "Aux" button
on Busses.

Leave processor box sensitive when editing aux-sends
This is required to toggle the strip to revert from aux-view
to the main route using the aux-send processor itself.

Discuss:
Perhaps this should be reverted, and ProcessorBox::edit_aux_send()
be removed: It is currently possible to create various
inconsistent mixer-states.

* use "Aux" on a Bus, then double-click some Internal-Send to
  revert strips. But Aux remains active
* Removing sends while "Aux" is active does not disable Aux.

If the processor box was insensitive those issues won't be present.
However it is convenient to use double-click on the editor-mixer to
access a send's panner ...

LCXL: make sends assignable for 32C
* add an option to the controller configuration gui
      to assign the 3x2 send banks in mixer mode
      to either the upper (1-6) or lower (7-12) Mixbus sends
    * This was a user request to better support the workflow
      of the CoMondo Mix system

Address sidechain-port name uniqueness
[Re]name sidechain port directly when a plugin is added.

Usually plugins are constructed without an Route (owner is unset).
PluginInsert c'tor may already create a side-chain port, at the
time of construction the sidechain port will be created using
the port-name "toBeRenamed".

Previously the plugin had to be added to a route using "add_processor",
in order to set a unique name, before a new plugin with sidechain
could be constructed.

ProcessorBox::use_plugins() did that in the correct sequence,
however there may have been cases where this didn't work, and
Route::add_processors() was called directly..

Fix loop-fade and de-click buffersize calculation
Exponential approach to zero:
     1 / exp(t) == exp (-t)
we "stretch" it by a time-constant "c":
        gain(t) = exp (-t * c)

To find the time t, at which the exponential approach reaches gain "g":
                                  exp (-c * t) = g
take the log of both sides:  log (exp (-c * t) =  log (g)
since  log (exp (x)) == x :               -c t =  log (g)
divide by -c              :                  t = -log (g) / c
set g = 1e-5 and c = _a/sr and we get:       t = -log (1e-5) / (_a/sr)

The iterative approach using g += c * (target_gain - g);
converges faster than the exact exp() calculation.

Except with 32-bit float, if target-gain is 1.0f and "c" is small.

With 32bit float (1.0 - 1e-5) = .9999900 is represented as
   sign: +1 | mantissa: 0x7fff58 | exponent: 126
there are only 126 "steps" to 1.0. Rounding of the lowest
mantissa bit does matter. We have to assume worst-case,
and increase the required loop_fade_length buffersize.

vs. approaching 0, where there are over 2^110 steps between
zero and 1e-5.

79f0ad0533 fix missing MIDI playback by using correct (expanded) logic in DiskReader::declick_in_progress()
If use_transport_fades() is false, then the declick_amp will have its gain always set to the current target (no declick).
Therefore only testing if it has reached zero is not enough, we need to check if we are declicking at all.

Also require at least one device mode in the MIDNAM file (via assert) - consider anything else to be malformed

8242478da5 try to fix awful confusion and misbehavior for plugin-provided MIDNAM situations
We do not store the MIDNAM model as a GUIObject property if the using the plugin-provided MIDNAM. Selecting a different MIDNAM for
the plugin should now result in that choice being saved/restored correctly.

This all feels crazily complicated, but I don't want to change more of the architecture at this time

Prefer TLSF over realloc-pool for LuaProc
With 4MB RAM and 1.5MB locked base memory (C++ bindings),
TLSF has a better worst-case performance (-20% std-dev
execution time compared to realloc-pool).

Even though on average Realloc-Pool performs better (-9%
average time, compared to TLSF).

Fix rt-safety of LuaProc w/o chanmapping
Since Lua function arguments are not typed, there is no
explicit "const", and a function can always modify the parameter.

When passing `ChanMapping const&` as argument, the object is
copy constructed. In this specific case the std::map<> members
of ChanMapping allocate memory.

Passing a pointer to the object works around this issue.

LuaBridge later dereferences the object as needed when calling
c++ methods, and copy-construction would only happen later.
