NoteBaseDeleted signal is static so each MidiRegionView(MRV) gets notified
about the deletion of each NodeBase instance even if it is contained in another
MRV
The NoteBase and MRV classes are currently coupled anyway, so this change uses
the reference to the MRV parent to directly call the parent when the NoteBase
is deleted. This is all in the GUI thread so I'm not sure why a PBD::Signal was
being used?
If the MRV class is the only reference holder to the NoteBase class
then I'm not sure if a callback is needed, perhaps the MRV should just remove
the note from the selection before deleting it but I'm not that familiar with
the code.

NoteBase instances.

This is not a large Session, 1500 regions, 10000 notes so there is probably
some other funky stuff going on that needs fixing.
the actual issues is in the connection management:
bundle.cc:323: void ARDOUR::Bundle::connect(): Assertion `N == other->nchannels().n_total()' failed.
That could be resolved. However, combining tracks without panners will
almost never do what the user really wants, so this case has been
disabled for now.
Glib::operator<<(std::ostream&, Glib::ustring const&) involves
loadlocale which is not thread-safe on OSX.
This fixes various seemingly random crashes on OSX.
Fixes all kinds of miscellaneous issues with MCP. Also removes several theoretical pan modes, replace "Tracks"
pan mode with "Trim", and takes a tiny step towards view modes
