* Use an atomic reference count since the freeze-thread
can call use_playlist.
* Remove explicit argument to construct unused playlist
because playlists are unused by default. This also
lead to use-count becoming negative (or rather UINT32_MAX)
Make click & drag in the left-hand half of a region with the Timestretch
tool stretch the region on its left, leaving the end position of the new
time-stretched region in the same place as the end of the original.
Fix "warning: this statement may fall through [-Wimplicit-fallthrough=]",
caused by the misspelling of "fallthrough" as "fallthough" in
editor_ops.cc.
Note that if you use ccache, you'll need to clear its cache to actually
get rid of the warning, because the pre-processed file (with comments
removed) is identical before & after this change, and thus won't get
recompiled otherwise.
Fix the equivalent typos in marker.cc too, though in those cases there's
no actual warning, because presently all the fall-throughs are from empty
cases.
This fixes a random crash with stop-and-forget capture.
When aborting capture, the disk-writer can emit
midi_write_source->drop_references ()
in the butler thread, which leads to a direct call to
Session::remove_source.
This can happen before or after Region::source_deleted
is called which is initiated from the same signal.
Furthermore it was possible that Region::source deleted
was called concurrently from the UI thread via SourceRemoved
for whole file regions, which lead to memory corruption.
TransportMasterManager::destroy () destroys any remaining
TransportMasters which in turn unregister their ports.
However the PortEngine was already destroyed.
Deleting _track_canvas_viewport automatically destroys
any child Items. The LocationMarker's group was already destroyed
when ~ArdourMarker() runs and calls `delete group`.
So first delete the marker, then the canvas
When starting RangePlay while the transport is already rolling
the transport is now stopped (and de-clicked) before locating.
This should not clear the RangeStop event when it is caused
by a RangePlay request.
Since 4ad1c19166 "select all" etc no longer plays
all notes, and possibility to get a loud speaker-blasting
cacophony is greatly reduced.
We may still want to add some additional heuristics, or
special case drawing new notes/hits, but for now this it
is sensible to enable this by default.
Session::possible_states correctly filters files
and also directly returns sorted base-names.
We can remove the redundant `get_state_files_in_directory`
API now.

Editor::motion_handler() only updates the snap-cursor
when no drags are active. While dragging, Drag::motion is
responsible to set the cursor accordingly.
In many cases the snap-cursor simply remained stuck at
the most recent position. Since in many cases
(e.g. RubberbandSelectDrag) it makes no sense to show the
cursor, so Drag::start_grab now hides the cursor by default.
This also fixes cases where the cursor is shown, but
was displayed in the wrong location.
