The dsgetdcname() function is able to try just DNS lookup, just NetBIOS,
or start with DNS and fall back to NetBIOS. For "net ads join", we know
most of the time whether the name of the domain we're joining is a DNS
name or a NetBIOS name. In that case, it makes no sense to try both lookup
methods, especially that DNS may fail and we want to fall back from site-aware
DNS lookup to site-less DNS lookup, with no NetBIOS lookup in between.
This change lets "net ads join" tell libnet what is the type of the domain
name, if it is known.

Based on an idea by Volker to optimize cpu usage when
parsing struct share_mode_data entries.
Add a 64-bit sequence number to the share mode entry,
and after the entry is stored back in the db, cache
the in-memory version using talloc reparenting into the
memcache. The memcache key used is the same struct file_id
used as the key into the locking db.
On read, check if the locking db version sequence number
matches the in-memory cache, and if so reparent the
memcache version back onto the required memory context.
Saves all the ndr decoding when multiple accesses to the
same lock entry happen in succession.
Design also improved by Metze and Ira.

osServicePack paramater allows the default behaviour ( which is to use
the samba version string as the operatingSystemServicePack attribute )
to be overridden
Additionally make sure if blank string is passed that it is treated
as attribute deletion. This is necessary as values for the os attributes
are eventually passed to ads_modlist_add if the value is "" then the
attempt to add this attribute fails in the underlying ldap
'ldap_modfiy_ext_s' function. In this case we need to pass NULL as the
value to force deletion of the ldap attribute
