2bde40762a s3: rpc_server: Remove SAMR specific policy_handle_create() function
Now that we pass the handle type to the generic handle creation and find
functions we can drop the specific SAMR ones.

The policy_handle_create() function labeled the talloc chunk used to
allocate the handle's associated data, and the policy_handle_find() is
checking the name matches with the expected data. The check is performed
now by the generic functions based on the handle type so we can drop
these SAMR specific functions.

c7a4578d06 s3: pass DCE RPC handle type to create_policy_hnd
Various RPC services expect policy handles of a specific type.

s3 RPC server did not allow to create policy handles with a specific
type while actually requiring that policy handle type itself in some
places.

Make sure we are able to specify the policy on-wire handle type when
creating the policy handle. The changes follow s4 DCE RPC server
implementation.

The original logic to always set on-wire handle type to 0 can be tracked
down to commit fdeea341ed when we didn't
really know about differences in on-wire handle types.

All but LSA trusted domain RPC calls do not check the on-wire handle
type in s3 RPC server.

Fixes trusted domain operations when Samba RPC client attempts to call
s3 RPC server to perform lsa_lsaRSetForestTrustInformation in FreeIPA.
This fix is a pre-requisite for FreeIPA-FreeIPA forest trust.

The first pdu is always a BIND.

REQUEST pdus are only allowed once the authentication

A simple anonymous authentication is finished after the BIND.
