Subject: nisppass.c: Fixed incorrect parameter usage. nmbd_become_lmb.c: Add
 'force_new_election' parameter to some functions.                    This
 allows the start of the election to be done *after*                    the
 demotion from local master browser is done.                    Also changed
 code so release of 1d name is done                    immediately to allow
 other local master to gain it. nmbd_elections.c: Ensured no elections are run
 until we have registered                   the WORKGROUP<1e> name that we
 must listen on to participate                   in elections.
 nmbd_incomingdgrams.c: Use force_new_election code. nmbd_namelistdb.c: Make
 update_name_in_namelist static. nmbd_subnetdb.c: Fix bug in comparison
 function. We cannot use memcmp                    as structure packing may
 make this fail. nmbd_packets.c: Ensure that we only send one release packet
 when                 sending a broadcast packet. nmbd_workgroupdb.c: Ensure
 we put the correct value in the ElectionCriterion field. nmblib.c: Ensure
 make_nmb_name zero's the struct nmb_name. Jeremy.
