r21512: finish DsBind() in the DRSUAPI server:

Browse Source 
- fill in our on bind_info struct correctly
- remember the local and remote DsBindInfo28 struct
- remember the remote bind_buid

w2k3 now tries replicate using DsGetNCChanges() from us,
after the NET-API-BECOME-DC test created the domain controller
and replicated all data.

(But we still give a DCERPC fault in DsGetNCChanges()...)
