This is mostly a simple lexical search+replace but the absence of operator< for
std::weak_ptr<T> leads to some complications, particularly with Evoral::Sequence
and ExportPortChannel.
This API is not official, and the upcoming official API differs.
The source-code is left in-place since most of it will be
re-usable as-is, regardless.

This also removes Route::group_gain_control() and associated machinery.
Not yet tested with Mackie or other surfaces. More work to done to
start using the group capabilities, and also potentially to add
or derive more controls as RouteAutomationControls
If a parameter change is initiated by the UI, the host sends a
notifications to confirm (echo) or invalidates (replaces) the value.
(automation: touch, playback,...).
Stateless LV2 GUIs without internal data-model depend on this.
The signal exists to notify listeners that something outside of the host's control (e.g. a plugin's own GUI for AU or VST)
has modified a plugin parameter. Previous code had strange feedback loops and ambiguous semantics.
Significant modification of LV2 GUI updating was required.
Still to be tested for feedback loop issues: AudioUnits
Before this, LV2 preset deletion in Ardour was doubly broken: the wrong file
was being removed, and removing the correct file would only result in a broken
preset. This change uses a new version of Lilv which has a more sophisticated
mechanism for preset deletion.
Also, fix "clashing" presets saved with the same name for different plugins, by
prefixing the plugin name to the bundle (this is now a recommendation in the
LV2 preset specification).
When the GUI is opened the first time all is fine, focus is on the
embedded widget. However once a user presses one of the preset buttons
(Add, Save,...) there is no possibility to return focus to the
embedded widget. Ardour always 'sees' it as focus=GtkButton and passes
the event to the editor.
Discard messages in LV2PluginUI::write_to_ui() if the
ringbuffer exists but the UI is not active.
This fixes "[ERROR]: Error writing from plugin to UI" messages
if the UI was once active but has been closed since.
This is a hotfix solution, eventually the LV2 backend should be updated
and a function LV2Plugin::disable_ui_emmission() implemented.
Don't ever clean up external UI plugins that use the LV2plug.in URI.
only free the memory of the last instance when the plugin is removed
or ardour closes.
