Add in the new Service Discovery Protocol API as announced previously in
http://mail-index.netbsd.org/tech-userlevel/2009/02/27/msg001764.html

  in lib/libbluetooth, add new SDP functions and bump minor version
  replace usr.sbin/sdpd with new version
  install sdp.h and sdp.3 from lib/libbluetooth

(Don't remove libsdp yet since some programs still refer to it)
