This is more correct than the original one:
It also hands the wellknown and "Unix Users" and "Unix Groups" sids to passdb
for id mapping.

This is to remove problems with the same unix-id being used both
as a uid and a gid.
The autorid backend will map a given number to the same SID, no matter whether this
is a uid or a gid. This will prime the idmap cache with mappings.
The sid-to-u/gid mapping, when not going through the cache, instead checks for
the type of the sid and only allows unix ids of the corresponding type.
Hence the rid backend will give different results, depending on whether the
cache is filled or not.
This patch lets the autorid backend always create sid->id mappings of type both.

This is the way the singular calls work and how they should (currently) work.
The two code paths need to give the same results. It is important to use
the passdb backend, otherwise groups don't work.

This will return the passdb domain if the given sid is in our sam or builtin
or is the domain sid of those domains. Otherwise it returns the idmap domain
that results from the idmap configuration.

This implicitly also hands the type of the resulting unix-id that the idmap
backend has created back to the caller. This is important for backends that
would set a broader type than the requested one, e.g. rid backend returning
BOTH instead of UID or GID.

The main purpose of the change is to hand the sid into the
idmap backend and handle responsiblity for handling the
sid-type correctly to the idmap backend instead of failing
directly when the sid is not of group type.
Hence backends like rid who are sid-type agnostic, can
return gids also for sids of other types. This is an important
fix to make sid_to_gid behave the consistently with and without
the presence of cache entries.
We need to additionally filter the result for id type GID
or more general (BOTH) to keep the behaviour.
This is a step towards using only one codepath to id_mapping.

- external part takes winbindd request/reponse structs (with sid strings)
- internal part takes sid lists
The new internal part implements functions wb_sids2xids_* that are
moved into the new module wb_sids2xids.c.
The purpose of this change is to use wb_sids2xids in winbindd_sid_to_uid
and winbindd_sid_to_gid instead of the currently used wb_sid2uid and wb_sid2gid.
We should just have one code path into id mapping and not several that behave
differently.

As this is a burst of 3 unbound sockets with each try to reach a DC
we're running out of file descriptors pretty fast. So winbind is then
mostly spinning in an accept loop failing with EMFILE.

Samba continues to query a broken DC while the DC did not finish to
rebuild Sysvol (after a Windows crash, for example). It causes end users
to received strange codes while trying to authenticate, even if there is
a secondary DC available.

This reverts commit ae6a779bf9f816680e724ede37324b7f5355996b.
Bug 9125 analysis from Volker:
The problem is that there are no network calls possible at all that
would do what the samlogon cache does for us. There is just no way to
retrieve the group membership in a complex trusted environment. If you
have just a single domain with Samba as domain controller it might be
possible, but even within a single domain it is not possible to
correctly retrieve all group memberships using LDAP calls due to ACLs on
directory objects. The call to get that is called NetSamLogon on the
NETLOGON pipe. But this call requires user credentials and might trigger
updating counts on the server. So to correctly implement wbinfo -r after
a user has logged in, you have two alternatives: Save the info3 struct
or the PAC in the netsamlogon cache. If you insist on doing network
calls, you need to cache the user credentials somewhere to re-do the
NetSamLogon call every time the wbinfo -r is requested.

The removal of consumption of the time field from the centry
as "removal of unused variable" in 21528da9cd12a4f5c3792a482a5d18fe946a6f7a
had the side effect of changing the offset for reading the following
nt password hash, so the read password hash was wrong.
This patch re-installs the consumption of the time,
thereby fixing the bug without changing the disk format of the cache.
