Various small fixes (trivial).

 - Add missing contributors to the README.

 - Drop obsolete -D option from manpage.

 - Only list contributors who added non-trivial amounts of code as copyright
   holders (and do not list those who merely provided register dump support
   for Super I/Os). Those contributors are still listed in the README,
   of course. See discussion in the thread starting at
   http://www.linuxbios.org/pipermail/linuxbios/2007-October/025516.html

 - Make a function static.

 - Fix incorrect URL in code comment. Drop obsolete comments.
