Rewrite the serbb code so the pin numbering matches the 

DB9 connector, and fix some related bugs in serbb_posix.c.

Closes bug #16265: dasa2 does not work under posix

* avrdude.conf.in: New serbb pin numbering; added "siprog"
as an alias for "ponyser".
* serbb_posix.c: New pin numbering, fix some confusion.
* serbb_win32.c: New pin numbering.

The generic and Posix-related parts of these changes have
been contributed by Hanns-Konrad Unger
