There are a number of different kinds of Verilog code blocks we'd
write, including:

(1) Simulation prototypes of something we want to synthesize
(2) Synthesizable version of (1)
(3) Test harnesses specifically for (1) and (2)
(4) Library code that's generally useful for all sorts of different situations

In general, for a specific block, like the video controller, I'd like
to keep (1), (2), and (3) in basically the same place, although it may
be sensible in many cases to have subdirectories that contain these
different pieces.  I think this would keep things coherent.  Related
items go together, and you can think of the pieces as a project unto
themselves.

But we also will want to collect a library of generally useful things,
and that would go somewhere else, I guess.

I'm getting further behind on things, unfortulately, so your patch is
slipping further down my list of emails.  This is why I'd like to give
you write access.  What are the general nature of your changes?
