GENSEC, and to pull SCHANNEL into GENSEC, by making it less 'special'.
GENSEC now no longer has it's own handling of 'set username' etc,
instead it uses cli_credentials calls.
In order to link the credentails code right though Samba, a lot of
interfaces have changed to remove 'username, domain, password'
arguments, and these have been replaced with a single 'struct
cli_credentials'.
In the session setup code, a new parameter 'workgroup' contains the
client/server current workgroup, which seems unrelated to the
authentication exchange (it was being filled in from the auth info).
This allows in particular kerberos to only call back for passwords
when it actually needs to perform the kinit.
The kerberos code has been modified not to use the SPNEGO provided
'principal name' (in the mechListMIC), but to instead use the name the
host was connected to as. This better matches Microsoft behaviour,
is more secure and allows better use of standard kerberos functions.
To achieve this, I made changes to our socket code so that the
hostname (before name resolution) is now recorded on the socket.
In schannel, most of the code from librpc/rpc/dcerpc_schannel.c is now
in libcli/auth/schannel.c, and it looks much more like a standard
GENSEC module. The actual sign/seal code moved to
libcli/auth/schannel_sign.c in a previous commit.
The schannel credentails structure is now merged with the rest of the
credentails, as many of the values (username, workstation, domain)
where already present there. This makes handling this in a generic
manner much easier, as there is no longer a custom entry-point.
The auth_domain module continues to be developed, but is now just as
functional as auth_winbind. The changes here are consequential to the
schannel changes.
The only removed function at this point is the RPC-LOGIN test
(simulating the load of a WinXP login), which needs much more work to
clean it up (it contains copies of too much code from all over the
torture suite, and I havn't been able to penetrate its 'structure').

handle the inverted memory hierarchy that a normal session
establishment gave. The inverted hierarchy came from that fact that
you first establish a socket, then a transport, then a session and
finally a tree. That leads to the socket being at the top of the
memory hierarchy and the tree at the bottom, which makes no sense from
the users point of view, as they want to be able to free the tree and
have everything disappear.
The core problem was that the libcli interface didn't distinguish
between establishing a primary context and a secondary context. If you
establish a 2nd session on a transport then you want the transport to
be referenced by the session, whereas if you establish a primary
session then you want the transport to be a child of the session.
To fix this I have added "parent_ctx" and "primary" arguments to the
libcli intialisation functions. This makes using the library much
easier, and gives us a memory hierarchy that makes much more sense.
I was prompted to do this by a bug in the cifs backend, which was
caused by the socket not being properly torn down on a disconnect due
to the inverted memory hierarchy.

encapsulates all the different session setup methods, including the
multi-pass spnego code.
I have hooked this into all the places that previously used the
RAW_SESSSETUP_GENERIC method, and have removed the old
RAW_SESSSETUP_GENERIC code from clisession.c and clitree.c. A nice
side effect is that these two modules are now very simple again, back
to being "raw" session setup handling, which was what was originally
intended.
I have also used this to replace the session setup code in the
smb_composite_connect() code, and used that to build a very simple
replacement for smbcli_tree_full_connection().
As a result, smbclient, smbtorture and all our other SMB connection
code now goes via these composite async functions. That should give
them a good workout!

rather than manual reference counts
- properly support SMBexit in the cifs and posix backends
- added a logoff method to all backends
With these changes the RAW-CONTEXT test now passes against the posix backend
