tidied up: code shuffling and documentation.

created namedb*.c nameservresp.c nameservreply.c and namepacket.c
added modules to Makefile, downloading dan's current version first :-)
shuffled docs to match source
created more docs

fixed bug in announce_backup() discovered when going nameannounce.doc:
backup list requests to the master browser should be used when samba is
not a master browser; backup list requests to the primary domain
controller should be used when samba is not a primary domain controller.

fixed bug in sync_server: it would never send MasterAnnounce packets.

removed the code that ignored special browser names: these should only
be ignored (except 0x1b names) when broadcasted name queries are sent,
not when directed registration or directed queries are sent samba as a
WINS server. (note: exactly what's going on is still uncertain).

renamed NAME_QUERY_MST_SRV_CHK  to NAME_QUERY_PDC_SRV_CHK  (more accurate).
renamed NAME_STATUS_MST_SRV_CHK to NAME_STATUS_PDC_SRV_CHK (more accurate).

added secured WINS name registration: a new 'state' NAME_REGISTER_CHALLENGE;
functions send_name_response(), response_name_query_register(); added
sending of WAIT ACKNOWLEDGEMENT packet; added a reply_to_ip field to
the response record structure so that after the name query challenge,
you know who to inform of the outcome of that challenge.

note: these are all currently untested modifications (yikes!)

+this module contains non-threaded versions of name status and name
+query functions. if a multi-threaded nmbd was to be written, these
+functions would be the starting point.
+
+at the moment, the expected response queueing system is used to
+replace these functions without needing to multi-thread nmbd.
+
+these functions are used in smbclient and nmblookup at present to
+avoid having the vast quantities of complex and unused code needed
+to support even a simple name query (or providing stubs for the
+unused side of these functions).
+
+there is a down-side to these functions, which is all microsoft's
+fault. microsoft machines always always reply to queries on the
+priveleged ports, rather than following the usual tcp/ip mechanism
+of replying on the client's port (the exception to this i am led
+to believe is windows nt 3.50).
+
+as a result of this, in order to receive a response to a name
+query from a microsoft machine, we must be able to listen on
+the priveleged netbios name server ports. this is simply not
+possible with some versions of unix, unless you have root access.
+
+it is also not possible if you run smbclient or nmblookup on an
+interface that already has been claimed by the netbios name server
+daemon nmbd.
+
+all in all, i wish that microsoft would fix this.
+
+a solution does exist: nmbd _does_ actually reply on the client's
+port, so if smbclient and nmblookup were to use nmbd as a proxy
+forwarder of queries (or to use samba's WINS capabilities) then
+a query could be made without needing access to the priveleged
+ports. in order to do this properly, samba must implement secured
+netbios name server functionality (see rfc1001.txt 15.1.6).
