rewrote nmbd's wins backend to use a tdb instead of a flat text file.
Changed the way the wins record are handled in memory. Now they are living much longer with the different states: active, released and tombstone. Also added a version ID, some wins flags and the wins owner ip address to the namrec->data struct, and a function to process messages sent by the wins replication daemon. the initiate_wins_processing() function is not correct, I'll fix it later. J.F. (This used to be commit b902e087d06c32797af19021a7f56895d86d7364)
