All the obvious MementoCommand grunt work. Now there's some
add_undo/add_redo_no_execute sprinkled around where one is separated from the
other (e.g. in different callbacks) or perhaps even where there's only an undo
and no redo. Also some sigc-based undo/redo pairs that probably need their own
Command class.

Added mac specific ardour2_mac_ui.rc file
Fixed some memory leaks in add_instant_xml() usage.
Added EXTRA_WARN scons option for pedants.
Reformatted xml++.cc into something that wouldn't drive me insane.

This is the first swath of changes, replacing add_undo with MementoCommand
pattern, through most of the editor_mouse.cc file. However there were a few
places that weren't symmetrical that I need to think about. The question is
whether to tweak things so that they are symmetrical (add_undo paired with
add_redo*), or to allow Commands to not be undoable or not be redoable. Your
thoughts are welcome.

I just had an epiphany. I tried so many ways to make saving function name and
args work, it never occured to me that you could just as easily save undo
information as a pair of mementos, even in the Command-based structure we
agreed on.
Since many (read: almost all) existing undo commands take this form:
begin_reversible_command (_("change fade in length"));
session->add_undo (arv->region.get_memento());
arv->region.set_fade_in_length (fade_length);
session->add_redo_no_execute (arv->region.get_memento());
commit_reversible_command ();
We are already doing the save a memento before and after work. All we need to
do is instantiate an appropriate instance of MementoCommand. So the above
becomes:
begin_reversible_command (_("change fade in length"));
MementoCommand<arv_region_t, arv_region_memento_t> before, after;
before = arv->region.get_memento();
arv->region.set_fade_in_length (fade_length);
after = arv->region.get_memento();
session->add_command(arv->region, before, after);
commit_reversible_command ();
(With apologies for being too lazy to go look up what arv_region_t and
arv_region_memento_t are)
Note that the true command approach is still possible, and encouraged (both by
dictate and design).

Renamed pbd3 back to pbd, since it's version 4.1 now.
Very minor fixes

Coding for undo/redo starts in earnest. Paul and I decided to go with a
standard gang of four Command pattern, with serialization. This overcomes the
terrible difficulties we were having with static type checking and the sigc++
approach. I'm adding the requirement that each command support undo,
simplifying undo/redo. NOTE that an important fallout here is that
Command::operator()() is the opposite of the old UndoAction::operator()(), i.e.
Command::operator()() is execute/redo, and Command::undo() is undo.
This commit is a reworking of the infrastructure, and won't compile until
creating Command subclasses for the various commands being performed. That is
primarily where you find get_memento and/or calls to add_(undo|redo.*).
