MS-SMB2 3.3.5.9.11 Handling the SMB2_CREATE_REQUEST_LEASE_V2 Create Context:
If the SMB2_LEASE_FLAG_PARENT_LEASE_KEY_SET bit is set in the Flags field of
the request, Lease.ParentLeaseKey MUST be set to the ParentLeaseKey of the
request.

Check for open files recursively when renaming a directory and wait for handle
lease breaks.
As delay_for_handle_lease_break_send() does the same check as
have_file_open_below(), remove have_file_open_below() from can_rename() so it is
not called twice for SMB2 renames, and add calls to have_file_open_below() to the
SMB1 entry rename entry points.
This is a bit ugly, but I don't see any other good way of doing this.

We must also break leases on other opens if the open of the rename doesn't have
a lease itself. The existing test test_lease_v2_rename() that was added
alongside the deferred rename server code didn't cover this case.

For a compound related request chain of eg CREATE+NOTIFY+GETINFO, the NOTIFY
will typically go async. When this is noted in smbd_smb2_request_pending_queue()
the pending async tevent_req is cancelled which means we return
NT_STATUS_CANCELLED to the client while Windows returns
NT_STATUS_INTERNAL_ERROR.

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.
