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.
This change still runs the triggerbox during latency-preroll, but as with the disk reader,
the transport speed argument is set to zero. The triggerbox notices this and behaves
appropriately (I think !)
When an archive are saved, a new folder in interchange/ is created,
named after the archive. However session-archive also retains files
in the session-folder that Ardour does not know about.
This can cause that the the original interchange folder is retained.
It will be empty with just the .DS_Store file in it. The result is
that the session may not load if there is an ambiguity.
Triggerboxen were being executed during the latency preroll phase, which is
inappropriate. ::fast_forward() will prepare them to run at precisely the
correct time. So we add an explicit clause to avoid this.

Rather than start at zero, we now search backwards for the first relevant cue
before the locate position, making our task in ffwd'ing from there much simpler
since there are no other cues to consider
Also remove Meter:: versions of related methods, because they are not necessary. We
only need metrical information for operations like ::round_to_bar()
* there are rare cases where a midi clip would not advance the ffwd position, looping endlessly
* this problem did not occur when the user chose an explicit Follow Length (different code path)
This workaround bypasses RegionMap and SessionPlaylist APIs
(region_use_count, destroy_region) which are not directly
applicable to Triggerboxes. There are likely various edge
cases until TriggerBoxes integrate with Session Playlist.
e.g. whole file regions generated for regions/source used by
triggerboxes are cleaned up.
A compound region itself may be unused, but the nested source
it provides can be used in another region compound.
In this case the first, unused, region needs to be saved
to save the nested source.
Constructing a playlist from another playlist plus an offset used the wrong
RegionFactory::create method. By failing to pass in the offset to the region
constructor, the newly created region gets its envelope (and possibly other
automation data) from the start of the existing region, not its own start.
