[Yaffs] Frank's mega-patchset

First off I'd really like to thank Frank for his efforts here.

Thanks Frank for structuring the patches in neat logical sets.

Herewith a brief analysis of the patches and what I intend to do about them:

Patchset 1 really copies almost the whole of yaffs, including some obsolete
and test code, into the kernel tree. This is not the best way to do this,
IMHO. What I'd rather do is write a patch_in script which either copies the
useful files into the kernel from a freestanding YAFFS CVS snapshot or
creates symlinks. Anyone who's used the mtd patchin will know what I'm
talking about.

Patchset 2 is a useful kernel makefile and KConfig. These will go into a new
directory in yaffs called yaffs/linux-kernel. These will get copied/symlinked
by the patchin.

Patchsets 3..8 Various tidy ups and tweaks, some fixes more recent kernel
changes too. These I will apply, though some of them will have to be done
manually to prevent breaking other OSs.

I'm doing a tag befora applying these changes.
