As per Simo's comments in https://bugzilla.redhat.com/show_bug.cgi?id=1279249
we need Samba to return the correct thing to the client when gss_accept_sec_context
returns a token along with an error.

This improved code simply cleans up the memory as soon as possible,
rather than using memcmp(). Otherwise, we segfault if
krb5_kt_start_seq_get fails, as it can set the fd element in the
handle to -1.

We should treat most gensec related structures private.
It's a long way, but this is a start.

This is clearly a utiliy function generic to gensec. Also the 3 callers
had identical implementations. Provide a generic implementation for all
of them and avoid duplicating the code everywhere.

gensec_update() ensures that DCE-style and sign/seal are negotiated correctly
for DCE/RPC pipes. Also, the smb sealing client/server already check for the
gensec_have_feature().
This additional check just keeps causing trouble, and is 'protecting'
an already secure negoitated exchange.

This ensures that we use the same SPNEGO code on session setup and on
DCE/RPC binds, and simplfies the calling code as spnego is no longer
a special case in cli_pipe.c
A special case wrapper function remains to avoid changing the
application layer callers in this patch.

Using gss_krb5_export_lucid_sec_context() is a problem with MIT krb5, as
it (reasonably, I suppose) invalidates the gssapi context on which it
is called. Instead, we look to the type of session key which is
negotiated, and see if it not AES (or newer).
If we negotiated AES or newer, then we set GENSEC_FEATURE_NEW_SPENGO
so that we know to generate valid mechListMic values in SPNEGO.

This matches the behavior of ads_verify_ticket().
Note that ads_verify_ticket() calls krb5_to_nt_status(), but
as a server it's likely to always returns NT_STATUS_UNSUCCESSFUL.
ads_verify_ticket() maps NT_STATUS_UNSUCCESSFUL to NT_STATUS_LOGON_FAILURE.

The GSE layer is now used via the GENSEC module, so we do not need these

This simplifies a lot of code, as we know we are always dealing
with a struct gensec_security, and allows the gensec module being
used to implement GSSAPI to be swapped for AD-server operation.
