r6028: A MAJOR update to intergrate the new credentails system fully with

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').
