This allows to move or copy whole sections of the timline (everything
you hear) to a differnt position on the timeline.
NB. Markers and tempo-map are not yet moved, and interpolated MIDI
events are lost.
This fixes a crash when deleting routes, while there are still
automation events queued for the route.
Specifically, SoloControl has a reference Soloable& _soloable; which
points to the parent route. A rt-event can still hold a valid shared
pointer to the SoloControl, even if the route is destroyed.
Calling SoloControl::actually_set_value is fine (the control still
exists due to the shared ptr), but then checking the parent route:
```
if (_soloable.is_safe() || !can_solo())
```
accesses the already deleted route, which causes a crash.
The solution implemented here is to not bind a shared_ptr to the
realtime event. However, since deletion of the route happens in the main
UI thread, there may or may not still be a race.
Grid controllers will largely want to access clips in the order they appear on the Cue page
It is up to the device (and/or its ControlProtocol) to handle banking
Add a list of marker locations to the session, for the the UI to add the
current location to when "add-region-cue-marker" happens whilst recording.
On record-stop, create source markers at the locations in that list in all
newly-recorded audio regions.
if a slot becomes active, and the transport is not rolling, it still
asks the transport to roll. however, (1) there's only 1 request across
all triggerboxen (2) the request will not be handled till the next
process cycle (3) the triggerbox returns after the request i.e. it
waits until the transport is rolling
No behavior should be changed by this modification; the argument has a default value of false, which
matches previous semantics, and every instance where the argument is specified, it is given as false.
Session::route_processors_changed accumulates signals emitted
in realtime and processing is delegated to a dedicated rt-safe
thread. Previously this resulted in any changed to be converted
to a `GeneralChange`, which unconditionally triggered a route-reorder.
Record-arming a track causes a MeterPointChange (meters change to "in"),
and this caused routes to be resorted and a latency-update.
While the former is reasonable (Ardour prefers to process
rec-armed routes first), the latter certainly is not.
This allows to pass any GraphChain to the Graph to process.
It removes the need to use a mutex to swap two dedicated
chains (setup-chain <> active-chain, pending-chain).
Also various special cases pertaining to graph interaction
while auditioning and route-deletion can be removed.
This also unconditionally creates a graph-thread for GraphChains
to be processed, even if the main callback uses a special-cased
sorted RouteList if there is only one process thread.
The process-graph should only be concerned with GraphNodes,
which may or may not be Routes.
This also removes intrinsic connection information from
the graph-node. Connection information is to be kept separate
from the nodes.
When the graph is re-calculated in the background, old information
has to be retained until the new graph becomes active.
Previously *new* information was already stored in the nodes
while the graph is sorted, even though the new graph was not
active.

We know when we call non_realtime_stop() if we will be subsequently
locating. If so, do not do an additional non_realtime_locate() from
within the stop.
In order to detect if route delaylines need to be updated,
aux-send delaylines need to be updated first. This was previously
done directly in the latency-callback, which may be concurrent
with processing.
Now only the information (pending_delay) is set, and the actual
change happens later at the end of process().
block_processing() may hold the process-lock, waiting
for the latency-lock. at the same time audio-engine
may hold the latter, trying to acquire the former.
Somewhat alarmed that gcc (at least) allows if (cue_recording ...) to be
used just like if (_cue_recording) even though the former is a class method
and the latter is a class member.
