b2d1e44f59 r19249: Attempt to fix a site lookup bug found by Guenther. 
- "The problem is, with a fresh system, we don't know our sitename,
therefor we do a stupid DNS query for all DCs. The reply we get is a
round-robin list of all 21 DCs, we just pick the first, contact that
and safe that INET.COM#1C query in the name cache for later use...
What we need to do if we don't yet know our sitename, is to contact to
any DC, get the CLDAP reply to tell us in which site we are, then flush
the namecache and requery DNS including the sitename"

Implement the flushing of the #1C entries for a given NetBIOS name/realm
when looking up the site value.

554e68887b r18312: Change gencache_get slightly: Delete expired keys, and only strdup the value 
if a valid entry was found. The newer calls got the latter one wrong, change
the older calls.

77fe2a3d74 r18006: Actually a smaller change than it looks. Leverage 
the get_dc_list code to get the _kerberos. names
for site support. This way we don't depend on one
KDC to do ticket refresh. Even though we know it's
up when we add it, it may go down when we're trying
to refresh.

d7f7fcda42 large change: 
*)  consolidates the dc location routines again (dns
    and netbios)  get_dc_list() or get_sorted_dc_list()
    is the authoritative means of locating DC's again.

    (also inludes a flag to get_dc_list() to define
     if this should be a DNS only lookup or not)

    (however, if you set "name resolve order = hosts wins"
     you could still get DNS queries for domain name IFF
     ldap_domain2hostlist() fails.  The answer?  Fix your DNS
     setup)

*)  enabled DOMAIN<0x1c> lookups to be funneled through
    resolve_hosts resulting in a call to ldap_domain2hostlist()
    if lp_security() == SEC_ADS

*)  enables name cache for winbind ADS backend

*)  enable the negative connection cache for winbind
    ADS backend

*)  removes some old dead code

*)  consolidates some duplicate code

*)  moves the internal_name_resolve() to use an IP/port pair
    to deal with SRV RR dns replies.  The namecache code
    also supports the IP:port syntax now as well.

*)  removes 'ads server' and moves the functionality back
    into 'password server' (which can support "hostname:port"
    syntax now but works fine with defaults depending on
    the value of lp_security())

dad31483b3 Merge of netbios namecache code from APPLIANCE_HEAD. 
Tridge suggested a generic caching mechanism for Samba to avoid the
proliferation of little cache files hanging around limpet like in the
locks directory.  Someone should probably implement this at some
stage.
