r5108: the beginnings of a nbtd server for Samba4. Currently just displays the packets it receives, but it at least shows how the server structure will work. To implement it I extended the libcli/nbt/ library to allow for an incoming packet handler to be registered. That allows the nbt client library to be used for low level processing of the nbtd server packets. Other changes: - made the socket library always set SO_REUSEADDR when binding to an interface, to ensure that restarts of a server don't have to wait for a couple of minutes. - made the nbt port configurable. Defaults to 137, but other ports will be useful for testing. (This used to be commit 2fedca6adfd4df9e85cc86896dfa79630777a917)

r5114: the nbtd task can now act as a basic B-node server. It registers its names on the network and answers name queries. Lots of details are still missing, but at least this now means you don't need a Samba3 nmbd to use Samba4. missing pieces include: - name registrations should be "shout 3 times, then demand" - no WINS server yet - no master browser code (This used to be commit d7d31fdc6670f026f96b50e51a4de19f0b920e5b)
