Instead of ‘int’ or ‘uint32_t’, neither of which convey much meaning,
consistently use a newly added type to hold NDR_ flags.

We often loop over the array of domain children. However, the size of
the array is calculated as lp_winbind_max_domain_connections() which can
change (it is based on smb.conf). The fix is the talloc_array_length().
Reproducer:
winbind max domain connections = 100
smbcontrol all reload-config
smbcontrol all debug 10
/var/log/samba/log.winbindd shows many lines with random garbage pid:

Call depth is not working for winbindd_list_users_send as expected,
it is visible in the flow traces:
-> process_request_send
-> winbindd_list_users_send
-> wb_query_user_list_send
It should look like:
-> process_request_send
-> winbindd_list_users_send
-> wb_query_user_list_send
Tevent call depth tracking internal implementation relies on the fact
that the talloc memory context has type "struct tevent_req".
Then it can obtain the depth from the parent and increment it by one.
The implementation of winbindd_list_users_send() is passing to
wb_query_user_list_send() context of type
"struct winbindd_list_users_state", and from there the parent
"struct tevent_req" cannot be identified.
So we will pass as TALLOC_CTX 'state' instead of 'state->domains'.
After the call, we can reparent back.

When we were not able to get a valid response from any DC we should
report NT_STATUS_NO_LOGON_SERVERS with authoritative = 1.
This matches what windows does. In a chain of transitive
trusts the ACCESS_DENIED/authoritative=0 is not propagated,
instead NT_STATUS_NO_LOGON_SERVERS/authoritative=1 is
passed along the chain if there's no other DC is available.
