- when registering with a WINS server, initially use multi-homed
registration, then switch to name refresh requests. Send refresh
requests only to the WINS server that responded to our
registration. If that server goes away, then start the registration
from scratch. This makes registration more robust to WINS server
failure.
- send WINS registration requests out on our first interface rather
than an unbound interface, to avoid the problem of WACK replies
being sent to the wrong port (w2k3 WINS server does this)

- always try to enable broadcast on nbt name sockets (this matches
samba3 behaviour better)

be consistent with the function names
- added WINS client support to the NBT server. It will do initial WINS
registration, and WINS refresh, automatically failing over to
secondary WINS servers and handling multi-homed servers where we need
to register multiple IPs.
- added support for multi-homed name query replies, which are
essential for multi-homed registration as the WINS server will query
us to ensure we have the names when doing the secondary IPs in
multi-homed registration

make it possible to add optimisations to the events code such as
keeping the next timed event in a sorted list, and using epoll for
file descriptor events.
I also removed the loop events code, as it wasn't being used anywhere,
and changed timed events to always be one-shot (as adding a new timed
event in the event handler is so easy to do if needed)

bind twice on each interface, once using the broadcast address and
once using the specific IP. We then only listen on the wildcard
address if we don't have "bind interface only" set. This also happens
to simplify the code that finds the right interface for an incoming
request.

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

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.
