[ris-int] libbgpdump and autoconf

Hi James, the version of libbgpdump in the old TTM CVS used autoconf and automake to generate the configure script and makefiles, but in NCC CVS the configure script and makefiles are already there. I thought that it would be better to use autoconf and automake in CVS and that include the configure script only in release tarballs. Do you remember if you changed this for any particular reason? I was thinking of changing it back. Cheers, Lorenzo
