If we don't have a connection to a trusted domain but still try to do a
lookup we shouldn't segfault.

talloc_traverse_dict will return with -1 in case of an error and
might return positive values that indicate the count of found
entries

In itself, this is pretty pointless. But in the next steps I'll convert the
winbind internal communication to wb_reqtrans which allocates the request
properly. This minimizes the later diff.

* Adds wbcGetSidAliases that calls the lookup_useraliases function.
* Updates wbinfo and winbind_util.c to call the new function.
* Also added winbind_get_groups helper function.
"getent group" used to fill the idmap cache with negative
cache entries for unmapped group sids.
Don't pass domain name unconditionally to idmap_sid_to_gid().
idmap_sid_to_gid() only creates new mappings (allocating
idmap backends tdb, tdb2, ldap...) when the domain name passed
in is "".
Note that it is _wrong_ to directly call the idmap_sid_to_gid()
functions here, in the main winbindd. The correct fix would be
to send a sid_to_gid request to winbindd itself, but this needs
more work to prepare the async mechanisms, and we nee a quick
fix for getent passwd now.

With large groups, getgrent ran into timeouts because after each
single user that was added to the expanded group list, the list
was sorted and made unique.
Now the list is sorted just once after all members have been added.

Make sure that usernames are parsed using the correct separator.
Otherwise group memeberships in winbind may be result broken.

Attached is the companion patch to
(037b9689d9), which
made handling of WINBINDD_LIST_GROUPS asynchronous.
Because most all of the list_groups code was reusable, I abstracted it,
and implemented both list_groups and list_users on top of it.
On my large test domain a "wbinfo -u" call went from 70 seconds to 30
seconds with this patch. Plus, the parent process is no longer blocked
from receiving new requests during that time.

(This used to be commit 5188f28611)
Previously WINBINDD_LIST_GROUPS requests (ex: wbinfo -g) were handled by the
winbindd parent process in a sequential fashion. This patch, delegates the work
to the winbindd children so that the request is handled much faster in large
domain topologies, and doesn't block the parent from receiving new requests.
The core group enumeration and conversion that was handled in
winbindd_list_groups() has been moved into winbindd_dual_list_groups() to be
done by the child.
The parent winbindd_list_groups() simply calls each of the children
asynchronously.
listgroups_recv() aggregates the final group list that will be returned to the
client and tracks how many of the children have returned their lists.
The domain name of the child is passed back through the callbacks to be used in
debugging messages.
There are also several fixes to typos in various comments.
(This used to be commit 037b9689d9)
In getgrsid_lookupsid_recv() we use parse_domain_user which itself looks at
lp_winbind_separator(). Thus when building up that group name we should better
use it as well.
(This used to be commit 5df75578ef)
A user logging in via GDM was not getting a complete list of supplementary
groups in his/her token. This is because getgroup() was not able to
find the winbindd_domain* using the DNS name. Fallback to matching the DNS
name is the short name match failes.
