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.
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).
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.
ARDOUR::Session::remove_routes() explicitly calls
save_state (_current_snapshot_name)
Update assert() to treat an empty name
equivalently as explicitly specified _current_snapshot_name
undo may restore locations, which may trigger a state-save.
This can result in a deadlock:
Location::set_state () -> Locations::get_state()
both acquire a the same lock:

This is in preparation for saving state while the session is
record-arm'ed. Most notably config changes and undo/redo.
In case both normal and pending save happens, pending must be
last and is required to recover from crashes during recording.
This builds on top of 51d2bb:
* v6 routes templates/states have a version per <Route>
* older route-states are assumed to be from ardour-5
Stateful::loading_state_version 3002,
unless specified otherwise
Currently using Ardour-5 route templates (state version "3002")
with Ardour6 fails. As opposed to session-templates, Route
templates were not versioned.
This ensures future compatibility (and may allow to interpret
unversioned templates as "3002")
Loop recording creates a single long source, regions have to be
"split" from this source, using "start" as offset.
Since MIDI uses absolute timestamps, offsetting this by accumulating
buffer_position += (*ci)->samples;
like Track::use_captured_audio_sources() does, is not correct.
Furthermore, record_enabled() may be off when stopping recording,
MIDI needs to be flushed regardless.
DiskWriter::transport_looped() is called from the session
when engine loops. This does not take local disk-reader run()
latency offset into account.
finish_capture() needs to be postponed until the disk-writer
itself reaches the loop-position. This is achieved by
postponing loop() and calling it once loop-length of samples
has been captured.
This works because engaging loop always seeks to the loop-position
and first loop resets _capture_captured.
Ardour 5.x slave check was incorrectly ported to A6's TMM:
In Ardour 5 the comparison tested for *not* MTC:
```
if (!dynamic_cast<MTC_Slave*>(_slave)) { ..send MMC.. }
```
Other MMC messages (Record, Locate) are sent unconditionally.
This fixes an issue that after changing backends (::set_backend),
the session-transport was in inconsistent state. If it was rolling,
it continued to roll with "stop" being unavailable.
set_session_extents had a bug; it wasn't calling locations->add()
on the newly created location.
The correct implementation was in set_session_range_location,
but this was only called from one place.
This function was removed, and set_session_extents will be used in its place.
set_session_extents will create a session location if one no longer exists,
so there is no need for set_session_range_location.
