r4898: - removed the unused wins_srv_*() code
- expanded the generic async name resolver to try multiple methods - added wins resolutions to the list of methods tried - fixed up the random trn id generation to use the good random generator (This used to be commit 266fd2751c01808e5a18d4094032af50554ceb7a)

- This is pretty much a complete rewrite of the earlier code. The main
- aim of the rewrite is to add support for having multiple wins server
- lists, so Samba can register with multiple groups of wins servers
- and each group has a failover list of wins servers.
-
- Central to the way it all works is the idea of a wins server
- 'tag'. A wins tag is a label for a group of wins servers. For
- example if you use
-
- wins server = fred:192.168.2.10 mary:192.168.3.199 fred:192.168.2.61
-
- then you would have two groups of wins servers, one tagged with the
- name 'fred' and the other with the name 'mary'. I would usually
- recommend using interface names instead of 'fred' and 'mary' but
- they can be any alpha string.
-
- Now, how does it all work. Well, nmbd needs to register each of its
- IPs with each of its names once with each group of wins servers. So
- it tries registering with the first one mentioned in the list, then
- if that fails it marks that WINS server dead and moves onto the next
- one.
-
- In the client code things are a bit different. As each of the groups
- of wins servers is a separate name space we need to try each of the
- groups until we either succeed or we run out of wins servers to
- try. If we get a negative response from a wins server then that
- means the name doesn't exist in that group, so we give up on that
- group and move to the next group. If we don't get a response at all
- then maybe the wins server is down, in which case we need to
- failover to the next one for that group.
-
