This blob will be store in secrets.tdb. It makes it possible to store much
more useful details about the workstation trust.
The key feature that that triggered this change is the ability
to store details for the next password change before doing
the remote change. This will allow us to recover from failures.
While being there I also thought about possible new features,
which we may implement in the near future.
We also store the raw UTF16 like cleartext buffer as well as derived
keys like the NTHASH (arcfour-hmac-md5 key) and other kerberos keys.
This will allow us to avoid recalculating the keys for an in memory
keytab in future.
I also added pointer to an optional lsa_ForestTrustInformation structure,
which might be useful to implement multi-tenancy in future.

This is currently marked 'skip', which means it isn't stored in the
db, but printed out in ndr dump. However, this pointer can be invalid
if the lease_idx is set to 0xFFFFFFFF (invalid).
This is fixed up inside parse_share_modes(), but not until after
ndr_pull_share_mode_data() is called. If lease_idx == 0xFFFFFFFF
then ndr_print_share_mode_lease() prints an invalid value and
crashes.

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
