Re: [1.8.0] reorganize the mess that the source tree has become

I think a good code hygiene is important, and some suggestions here
are relevant:

1) I also think there should be a directory for the source code
(namely, src/), and the top level should act as a table of contents.
As a newcomer myself who's trying to grasp Git, I can say an organized
project makes people more inclined join. Therefore, directories should
be named as clearly as possible: see item 2;

2) For item 1, t/ should be renamed to testsuite/. As Junio said, if
we get a more organized project, people could just "cd t" and tab to
autocomplete, or "cd tes" at the worst scenario, which is not such a
big hassle. About people expecting the testsuite to be inside t/, once
they type "cd t" and get an error, most people would look for an
alternative and eventually find the correct folder, or tabbing would
just suggest the name.

3) The top level should hold files that point people towards where
they want to go, helpful files like README and even some
Documentation/ files could get a promotion.

3) As 1.8.0 can be an inflexion for users, so could be for the
developers as well.
