226c3ef7a6 gensec: make gensec_gssapi.h common
This will make it easier to share elements of the GSSAPI gensec mechs,
in much the same way elements of the NTLMSSP mech are shared.

3f5d30c8cb s4-gensec Remove fallback for simple privileges
This makes the dependencies simpler, as this code path is no longer
required.  (That is, it makes no sense to have an NTLM login without
an auth context, and the gensec_gssapi and gensec_krb5 modules call
the PAC blob function below instead).

149f8f16be s4-gensec: Move parsing of the PAC blob and creating the session_info into auth
This uses a single callback to handle the PAC from the DATA_BLOB
format until it becomes a struct auth_session_info.

This allows a seperation between the GSS acceptor code and the PAC
interpretation code based on the supplied auth context.

de553b52f2 s4:gensec/spnego: only try the mechs that match the client given ones
Windows-Members of NT4/Samba3 domains, send

MechTypes:
1.3.6.1.4.1.311.2.2.10 [NTLMSSP]
1.2.840.48018.1.2.2    [krb5 broken]
1.2.840.113554.1.2.2   [krb5]

MechToken for NTLMSSP.

This patch makes sure we start NTLMSSP with the given MechToken,
instead of trying to pass the NTLMSSP MechToken to the krb5 backend
first. As that would fail the authentication with an error
instead of trying fallbacks.

e7d5f0a357 gensec: move event context from gensec_*_init() to gensec_update()
This avoids keeping the event context around on a the gensec_security
context structure long term.

In the Samba3 server, the event context we either supply is a NULL
pointer as no server-side modules currently use the event context.

35b309fa0c gensec: clarify memory ownership for gensec_session_info() and gensec_session_key()
This is slightly less efficient, because we no longer keep a cache on
the gensec structures, but much clearer in terms of memory ownership.
Both gensec_session_info() and gensec_session_key() now take a mem_ctx
and put the result only on that context.

Some duplication of memory in the callers (who were rightly uncertain
about who was the rightful owner of the returned memory) has been
removed to compensate for the internal copy.
