All AD servers support "GSS-SPNEGO". So we better
remove code that doesn't use gensec.
If we ever need this back we could use the
"gssapi_krb5_sasl" gensec module explicit
or just pass the SASL mech list to gensec.

Prepare for rebasing libads on top of libsmbldap.
To make libads using 'struct smbldap_state' instead of direct LDAP
structure, we need to abstract out libads logic from connection
handling. SASL wrapping does not really depend on availability of LDAP
handle and does not need direct access to ADS_STRUCT. As result, we'll
be able to move SASL wrapping code under smbldap once the latter is able
to pass settings that libads passes to the SASL wrapping.

Avoid overriding default ccache for ads operations.
Nowadays various samba components may need to use GSSAPI and a default cred
cache to perform their tasks.
This code was completely overriding the whole process default ccache name, thus
altering the current credentials and sometimes hijacking them (or getting
preemptively hijaked).
By using gss_krb5_import_cred we can instead use a private ccache (necessary
sometimes to use a different set of credentials fromt he default
cifs/fqdn@realm one, for example when contacting foreign DCs using trust
credentials) that does not affect the rest of the process.
For the kerberos versions which don't have gss_krb5_import_cred
we fallback to temp override of KRB5CCNAME and gss_acquire_cred.

This principal is not supplied by later versions of windows, and using
it opens up some oportunities for man in the middle attacks. (Becuase
it isn't the name being contacted that is verified with the KDC).
This adds the option 'client use spnego principal' to the smb.conf (as
used in Samba4) to control this behaivour. As in Samba4, this
defaults to false.
Against 2008 servers, this will not change behaviour. Against earlier
servers, it may cause a downgrade to NTLMSSP more often, in
environments where server names are not registered with the KDC as
servicePrincipalName values.
