Some plugins call restartComponent(Vst::kParamTitlesChanged)
when their GUI is created, from the call that creates the UI.
This lead to a stack-overflow recursion in Ardour:
ProcessorBox::redisplay_processors -> VST3Plugin::has_editor
-> [plugin] -> VST3::restartComponent -> signal proc changed
-> ProcessorBox::redisplay processors
Since 62fc1d3c2e, Delivery buffers were flushed twice.
Once by copy_to_outputs() and again later by
Delivery::flush_buffers. This resulted in duplicate events
during export (see 576840c09e, MIDI buffers are not cleared
after flush to allow export processing to grab the data from
the port-buffers).
The workaround in 62fc1d3c2e is only relevant for ClickIO,
other Deliveries (Send is a Delivery) are explicitly flushed
by Route::flush_processor_buffers_locked.
This reverts commit 615326be9b because it
breaks windows builds.

Region::fade_range emits a signal which will call
ARDOUR::Playlist::region_bounds_changed, which takes a WriteLock.
That resulted in a WriteLock with ReadLock held.
CC is already set to a string. (And if it ever should be None, we want
to handle that explicitly.)
(And #autowaf.display_msg handle Booleans just fine.)
The sub_config_and_use function recursed, but it also invoked
autowaf.set_local_lib , which however didn't do anything useful. The
HAVE_ defines are not used anywhere, and the AUTOWAF_LOCAL defines are
only used in autowaf.use_lib, which however isn't used anywhere.
Dropping these defines simplify the build environment and makes the
compiler command line half as long and thus makes debugging much more
manageable.
Put it in the "children" list instead of recursing explicitly.
The only difference is that the (empty) options function in
libs/clearlooks-newer/wscript now will be invoked - before it wasn't.
https://waf.io/book/ says
By default, the project name and version are set to noname and 1.0. To
change them, it is necessary to provide two additional variables in
the top-level project file
- and waf code inspection confirms that waf itself only will use the top
level APPNAME.
autowaf has no real shutdown functionality anyway. The automatic
shutdown function that could have been called wouldn't work anyway, as
it takes an argument.
The only reason it doesn't fail is that the top level wscript has no
shutdown handling and doesn't recurse to other scripts, so it is all
dead code.
It turns out that slightly older versions of ALSA create different "pretty"
port names for USB MIDI devices than slightly newer ones. The new versions
use names that match those seen on other platforms.
This means that to do port matching on Linux now requires a regexp
to match the possible alternatives. This matters much more for the LPP,
which has 3 input ports and 3 output ports, than it does for most devices
that have a single input and single output, and we can "find" the ports
just using simple string searching
The kissfft library changed its SONAME and how the various libraries
were organized, e.g. the functions for complex and real numbers aren’t
in separate libraries anymore.

When using "VS" the numeric control shows the "default speed"
when not rolling. Then when starting to roll default speed will
be the actual speed.
Previously the shuttle was not updated when `last_speed_displayed`
was the current speed. This dated back to before "VS" showed
default speed.
