[PATCH] (preliminary) new fragtree build method

[Artem B. Bityuckiy]

Here is a newer version of the patch:
http://www.infradead.org/~dedekind/reverse-version-prelim-03.diff

The original mail: http://lists.infradead.org/pipermail/linux-mtd/2005-
July/013015.html

Except of the functional changes, I made a lot of the source code
cleaning. It is very difficult to post that in separate patches, so it
is in one patch.
