a2b6a68b80 schannel.idl: change netlogon_creds_CredentialState layout for 4.22
This breaks compat with 4.21 and moves stuff out of
netlogon_creds_CredentialState_extra_info.

It also prepares support for netr_ServerAuthenticateKerberos()

This reverts commit c3fa132fbe179bd4e1451240ce572ec791356a16.

We break the compat of the netlogon_creds_cli.tdb records compared to

85b2dcd938 dcerpc_util: let dcerpc_pull_auth_trailer() ignore data_and_pad for bind, alter, auth3
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.
