Unsigned long is 32bit on 32bit systems, besides sampleoffset and start
variables are signed int64_t.
resulting in a compiler error:
integer constant is too large for 'unsigned long' type.

set_block_size() implies plugin deactivate(), activate() calls
to re-initialize AU and VST plugins. So plugins will reset the
internal state and not immediately respond correctly.
Some plugins zero the output or ramp up internally, leading the analyzer
to show invalid or random/uncorrelated information.
This avoid periodic calls to de/activate()

Changing a tooltip resets the timeout. In one particular case,
while rolling, AudioClock::set() is calling set_tooltip() at a rate
faster than the tooltip timeout and prevents tooltip from showing at all
(even if there is no actual change to the tooltip text).
Alas, there is no trivial fix for this UI side and there may be other
such cases. A central check is more than practical.

- Disabled due to ptformat not knowing the length of sources
- Added MIDI region/track summary information to dialog

smf_delete() does not handle NULL, and segfaults instead.
This only crashes with optimized builds.
libsmf will call g_critical() earlier and in that case debug-builds
call UI::handle_fatal() and ask the user to "click to exit".

This fixes VST parameter prop.flags (toggle, integer-step).
VestigeMaxLabelLen is used in various places in libardour, most notably
with effGetParamName.

state, ability to work on selected tracks only, plus bugfixes and removal of redundant checks

It conveyed the idea of continuous silencing as long as the transport
is in a stopped state. Make it correctly mean a one-shot reset when the
transport is being stopped.

CoreMIDI ports are dynamic. When dis/connecting a device CoreAudio's
AudioHardware-PropertyListener triggers a callback which can
add/remove ports.
This can not happen concurrently with processing, but it may happen
concurrently with a user creating tracks using Ardour's UI
and/or session-load/setup.

Also fix duplicate of multiple regions in the same track, and change "gap" variable
name to "span" for greater clarity

Don't call ::set_value() if the actual value has not changed.
e.g. MIDI-CC or integer controls. Moving the Bar-controller was able to
create events even though the actual value remained unchanged.
This check has to be done UI-side, since the underlying API is also used
for state-restore and automation. e.g.
"old value" (user-set) may be default "0", "new value" may also be "0" but
libardour still needs to send an event (a synth's internal state may not
default to "0")

invoked for a button event
Only put the button into "consumed" if it actually invoked something.
This helps to get reverse-polarity footswitches to work as expected

kludge it by first casting to an integer type
(is it safe to be casting from float to enum anyway??)

..or as clang puts it:
"error: no member named 'labs' in namespace 'std'; did you mean
simply 'labs'?"

Drag a group-tab's right-edge horizontally to the right to remove all
current routes from the groups before adding new routes to the group.
The group becomes temporarily empty, and
Session::route_removed_from_route_group() removes the group (before new
routes can be added).

* Detach model from treeview and disable sorting during refill.
* Prevent multiple re-fills due to sensitivity updates of ComboBoxes:
gtk_widget_set_sensitive() -> CairoWidget::on_state_changed ()
-> CairoWidget::set_visual_state () -> StateChanged Signal

The Script-selector is used in various places, not just for
Action-scripts.
Also add a "--" prefix for the separator to avoid name conflicts with
actual script names.

Empirically this decreases gc-spike duration (worst-case) by a factor of
two and speeds up the average gc-run by a factor of over 4 (depending
on the amount of memory used by the plugin).

Add custom API to prevent Lua Objects from being garbage collected.
This is intended to for Ardour LuaBridge bindings (~1MB Objects:
tables, functions and userdata).
The bindings are persistent and the gc can skip them in mark & sweep
phases. This is a significant performance improvement for garbage
collection.
Note. The next version of Lua (5.4) will come with a generational-gc
rather than an incremental, so extending the API at this point in time
is acceptable.
