Big change to make nmbd code more readable/understandable.

Big change to make nmbd code more readable/understandable.

Main change is removal of find_name_search() confusion.
This has been replaced with find_name_on_subnet() which
makes it explicit what is being searched.

Also changed wins_subnet to be wins_client_subnet in
preparation for splitting the wins subnet into client
and server pieces.

This is a big nmbd change and I'd appreciate any
bug reports.

Specific changes follow :

asyncdns.c:
     Removed wins entry from add_netbios_entry(). This is now
     explicit in the subnet_record parameter.

interface.c:
     iface_bcast(), iface_nmask(), iface_ip() return the
     default interface if none can be found. Made this
     behavior explicit - some code in nmbd incorrectly
     depended upon this (reply_name_status() for instance).

nameannounce.c:
     find_name_search changes to find_name_on_subnet.

namebrowse.c:
     wins_subnet renamed to wins_client_subnet.

namedbname.c:
     find_name_search removed. find_name_on_subnet added.
     add_netbios_entry - wins parameter removed.

namedbsubnet.c:
     find_req_subnet removed - not explicit enough.

nameelect.c:
     wins_subnet renamed to wins_client_subnet.

namepacket.c:
     listening() simplified.

nameresp.c:
     wins_subnet renamed to wins_client_subnet.

nameserv.c:
     find_name_search moved to find_name_on_subnet.

nameserv.h:
     FIND_XXX  -> changed to FIND_SELF_NAME, FIND_ANY_NAME.

nameservreply.c:
     find_name_search moved to find_name_on_subnet.
     Debug entries changed.

nameservresp.c:
     wins_subnet renamed to wins_client_subnet.

namework.c:
     wins_subnet renamed to wins_client_subnet.

nmbd.c:
     wins parameter removed from add_netbios_entry.

nmbsync:
     wins_subnet renamed to wins_client_subnet.

proto.h: The usual.

server.c:
     remove accepted fd from fd_set.
