[dfmc,dylan] Remove usage of partial-dispatch engine node in value comparison.

This is probably a performance hit, but partial dispatch is going away,
so remove this for now.
[dfmc,dylan] Remove partial dispatch.

This isn't enabled usually and isn't a clear win for performance
and costs extra space.

Let's remove it to simplify.
Update testworks submodule.
Update testworks submodule, part deux.
[jamfiles] Refactor to share more between Darwin builds.
[jamfiles] Correctly deal with debug info on Mac OS X.

Mac OS X lazily links debug info. That is, it leaves it in the
various .o files until dsymutil is used to link the debug info
into a bundle. Doing this and then stripping our actual libraries
and executables should result in an improved out of the box experience.

[notebook] Stub version of Project Notebook.

This is where we'll record information about various projects
for Open Dylan. This would include future extensions or changes,
work that is ongoing, things that we'd like to clean up, research
into particularly troublesome issues, etc.

This isn't all stuff that belongs in the bug tracker as that's
being used for actual bugs.

It doesn't really belong in the wiki as that doesn't allow for
the description and write-ups to remain in sync with the code
as it changes / evolves.
[notebook] Brief intro.
[notebook] Stub out a lot of pages.
[notebook] Flesh out a couple of entries.
