- store the wins owner on the record and the wins owner and expire time on each address
- we use "0.0.0.0" to mark entries which are registered at the local wins server
- we use this ldif-format:

most of the changes are fixes to make all the ldb code compile without
warnings on gcc4. Unfortunately That required a lot of casts :-(
I have also added the start of an 'operational' module, which will
replace the timestamp module, plus add support for some other
operational attributes
In ldb_msg_*() I added some new utility functions to make the
operational module sane, and remove the 'ldb' argument from the
ldb_msg_add_*() functions. That argument was only needed back in the
early days of ldb when we didn't use the hierarchical talloc and thus
needed a place to get the allocation function from. Now its just a
pain to pass around everywhere.
Also added a ldb_debug_set() function that calls ldb_debug() plus sets
the result using ldb_set_errstring(). That saves on some awkward
coding in a few places.

authenticated session down into LDB. This associates a session info
structure with the open LDB, allowing a future ldb_ntacl module to
allow/deny operations on that basis.
Along the way, I cleaned up a few things, and added new helper functions
to assist. In particular the LSA pipe uses simpler queries for some of
the setup.
In ldap_server, I have removed the 'ldasrv:hacked' module, which hasn't
been worked on (other than making it continue to compile) since January,
and I think the features of this module are being put into ldb anyway.
I have also changed the partitions in ldap_server to be initialised
after the connection, with the private pointer used to associate the ldb
with the incoming session.

- move monitor_fn to libnet.
NOTE: I have maybe found some bugs, in code that is dirrectly in DONE or ERROR
state in the _send() function. I haven't fixed this bugs in this
commit! We may need some composite_trigger_*() functions or so.
And maybe some other generic helper functions...

domain and gets the DC's name via a mailslot call.
Metze, I renamed wbsrv_queue_reply to wbsrv_send_reply in accordance with
irpc_send_reply. Having _queue_ here and _send_ there is a bit confusing. And
as everything is async anyway, the semantics should not be too much of a
problem.

This gets it working, but I'm rather worried about the speed. We used
to get more than 5000 ops/sec, but now we are down to around 15
ops/sec. I suspect a bug in ldb.

replication support
- on a WACK registration success, check that the database record
hasn't changed during the WACK processing. If it has, then fail
the registration
(This used to be commit 2acd79b959)
- if we have no configured network interfaces, then don't start nbtd (when I add dynamic
interface loading this will change to a delay until a network interface comes up)
- choose the best interface by netmask for torture tests that need a
specific IP (such as the WINS test). Added iface_best_ip() for that.
- if specific interfaces are chosen in smb.conf, then keep that ordering, and
default to the first one listed

- more NBT packet asserts, to ensure that incoming requests have all
the elements we depend on
- open the WINS database at startup if we are configured as a WINS server
- split out the nbtd server reply packet generation code so it can be
shared by the WINS server
- re-did the logic of what is answered by the WINS server and what by
the B node server. It now always tries to answer by the B node, and
only "recurses" to the WINS server for names that are not found.
(This used to be commit 5613e6b8ad)
- change the iface_n_*() functions to return a "const char *" instead of a "struct ipv4_addr"
I think that in general we should move towards "const char *" for
all IP addresses, as this makes IPv6 much easier, and is also easier
to debug. Andrew, when you get a chance, could you fix some of the
auth code to use strings for IPs ?
- return a NTSTATUS error on bad name queries and node status instead
of using rcode. This makes the calling code simpler.
- added low level name release code in libcli/nbt/
- use a real IP in the register and wins nbt torture tests, as w2k3
WINS server silently rejects some operations that don't come from the
IP being used (eg. it says "yes" to a release, but does not in fact
release the name)
(This used to be commit bb1ab11d8e)
- 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)
(This used to be commit f7712ac746)
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

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.
