Writing partial messages will lead to undefined behavior.
This does not generally happen (LV2 forge prevents overflow
of the Atom buffer itself), however if the GUI is frozen messages
may accumulate in Ardour's Ringbuffer.
Processor::deactivate must not be called concurrently with
processing. e.g. Threading rules https://lv2plug.in/ns/lv2core
This fixes a potential crash when freezing tracks
* If 1 region is selected: suggest "Region-name (Bounced)"
* If more than one region is selected and ..
* all are on different tracks: allow to specify suffix.
* at least two regions are on the same track: hide the
"add to trigger-slot" option, allow to specify suffix

Since momentary override is a singleton, it needs to remain
GUI only, and not a session API available to any UI.
The middle-clicked button is rendered as pressed. So it is
already obvious and the Changed() signal that is emitted
when temporarily restoring a scene can simply be ignored.
* first_mark_after() correctly expects a timepos_t to compare with locations
* BUT the playhead position is always in samples, by definition
* in many cases this meant the 'next' marker was the one you are already located at
* also remove the slight distinction between playhead cursor and actual play position
(shouldn't matter, but...)
* in the past, the default behavior was: hiding a group would disable it,
and then showing the group would re-enable it
* problem occurs when user has disabled a group; hiding and showing it
unexpectedly re-enable the group
* there was a config variable to disable this behavior, but it was never
shown on the GUI and therefore not discoverable
Despite the longstanding policy, there's really no reason for
group visibility and enablement to be intertwined.
If this chnage causes a big problem for someone, they can revert to
the prior behavior by setting the new config variable in the text file
MP3 support was introduced in libsndfile 1.1.0 . It will be a simple
alternative to using external ffmpeg.
To avoid dependency on the new libsndfile or config-time checking,
hardcode the constants from sndfile.h . The actual availability will
have to be checked at runtime.
