Change kdd to 'Odd Fixes'.

kdd's knowledge of Windows kernel internals is several releases out of
date now.  However the underlying implementation of the serial protocol
is still sound.  I have heard that some people are using it, and I'm happy
to answer questions/bug reports, so don't deprecate it just yet.
