- fix a bug in NetServerEnum where counted and total were not counted
correctly if there were multiple instances of a name. This led to the
infamous "not enough memory" error when browsing (but this isn't the
only cause of that message)
- fix a triple-chaining bug which affected OpenX following a TconX
- fix a serious nmbd bug that meant nmdb would answer packets that it
wasn't supposed to, causing havoc with browse lists.
- never time out SELF packets. This is an interim fix until I find out
why nmbd thought they should be timed out.
