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.
amend to 4cdb018 and 1d972d0
override ui_closed() behavior for lv2ui:external
Keep UI around and do not re-instantiate, but simply show it again.
(this is against the original specs but was agreed upon by various
authors and the previous behavior or Ardour.)
kx:external-ui are cleaned up after ui_closed().
We send the full transport state (frame position, BBT time, transport speed,
meter) to the plugin:
* At the start of a cycle whenever a relocate or transport speed change has
occurred
* On every occurrence of a meter change within a cycle
This means the plugin gets a sample accurate meter/tempo map, even if the meter
changes in the middle of a cycle. However, this is not quite right yet: things
can get wonky if the tempo map is edited while rolling, since this code will
not detect the change and fail to update the plugin at the start of the cycle.
Other changes:
* Factor out TempoMetric::set_metric() and simplify some tempo functions
* Clean up LV2 URID stuff

It's slightly possible that this causes trivial build failures on different
configurations, but otherwise shouldn't cause any problems (i.e. no actual
changes other than include/naming/namespace stuff). I deliberately avoided
removing libardour-config.h since this can mysteriously break things, though a
few of those do seem to be unnecessary.
This commit only targets includes of ardour/*.h. There is also a very large
number of unnecessary includes of stuff in gtk2_ardour; tackling that should
also give a big improvement in build time when things are modified.

Ardour 3 now simply depends on the latest version of Lilv, which depends on the LV2 package (which contains all the LV2 headers).

Touch should allow custom plugin UIs to work properly with automation as the
generic UI does. IIRC this was requested for mixbus, however, no current
plugin UI I am aware of implements it, so it is completely untested.

Still a little bit rough around the edges, but it works. This can be tested
with the eg-sampler plugin from LV2 svn (whose UI can load different samples).

Fixes ticket #4067 (not to mention avoids having every UI that has ever been shown loaded in memory until exit time...)
