If LogonGetCapabilities was downgraded by an DCERPC Fault, we
rely on the schannel message ordering to detect failures.
Instead of letting any real winbindd request trigger this,
we do it directly in netlogon_creds_cli_check() with
a LogonControl that is also used for 'wbinfo --ping-dc'.

gsskrb5: let GSS_C_DCE_STYLE imply GSS_C_MUTUAL_FLAG as acceptor
Windows clients forget GSS_C_MUTUAL_FLAG in some situations where they
use GSS_C_DCE_STYLE, in the assumption that GSS_C_MUTUAL_FLAG is
implied.
Both Windows and MIT as server already imply GSS_C_MUTUAL_FLAG
when GSS_C_DCE_STYLE is used.

Sometimes Windows sends 3 presentation contexts (NDR32, NDR64,
BindTimeFeatureNegotiation) in the first BIND of an association.
Binding an additional connection to the association seems to
reuse the BIND buffer and just changes the num_contexts field from
3 to 2 and leaves the BindTimeFeatureNegotiation context as padding
in places.
Note, the auth_pad_length field is send as 0 in that case,
which means we need to ignore it completely, as well as any
padding before the auth header.
