Title: detect newer ortp version, update some autoconf files

This patch allows to use newer ortp version. As there is no version definition in ortp, I test against a function which I assume is new and did not exists before. If this does not work, the autoconf script needs to be adapted, so it checks against something which differs between new and old ortp.
