pgsql ODBC sources

I was poking through the backend source code working on the "name" data
type and stumbled on the (apparent) fact that NAMEDATALEN is defined to
be 32 bytes in the backend and only 16 bytes (the old backend value) in
interfaces/odbc/connection.h.

Also, some lines in the odbc sources seem to have a trailing ^M. Should
we add more, or take them out? :)
