* skip notes outside of region-range (source-start, region-length)
* handle tempo-ramps properly, apply map to stretch-fraction
* fix region properties after stretching
(position needs to be re-set first, to set a midi-region's
quarter-note position, which is used by the length calc)
tfsm events live on intrusive lists, with only 1 hook, which means they
can only be on one list at a time, and cannot be deleted while part of
the list. This wasn't being addressed properly when deferring (and
undeferring) events.
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.
Only when using JACK1 is ::update_latencies() a synchronous call (ending up in Session::update_latency() which tries to take the
same lock). But the semantics of ::update_latencies() are sufficiently ill-defined that entering that call with a lock held
seems like a bad idea, so we release the lock unconditionally here.
Let LV2 Plugin UI support (via SUIL) prefer and select a X11 UI whenever
multiple UI type options are provided by LV2 plugins (eg. Vee-One's do
present several but their native Qt5UI should never be raised by Ardour,
on any chance:)).

Remove need for explicit `initialize_latencies` call that used
to be called from GUI-thread post_engine_init(), as well as
Session::engine_running().
Further reduce calls, `graph_reordered` implies a latency-update
and fix ordering issue. update_latency_compensation() must be called
*after* resort_routes().
