mapped_state is a special hack for authenticate_ldap_simple_bind_send()
in order to avoid some additional work in authsam_check_password_internals()
This doesn't apply here. We should also handle wbinfo -a
authentication UPN names, e.g. administrator@DOMAIN,
even if the account belongs to the local sam.
With this change the behavior is consistent also locally on DCs and
also an RODC can handle these requests locally for cached accounts.

This is the big switch to use samba-dcerpcd for the RPC services in
source3/. It is a pretty big and unordered patch, but I don't see a
good way to split this up into more manageable pieces without
sacrificing bisectability even more. Probably I could cut out a few
small ones, but a major architechtural switch like this will always be
messy.

Handling of logfile name for main and child winbindd must ensure:
1) Log directory is selected in this order:
* -l option of winbindd
* "log file" parameter in smb.conf
* compile time value '/usr/local/samba/var'
2) Log filename pattern
* parent process uses log.winbindd
* child uses log.wb-<name>
3) Log reopen works for both parent and child (i.e. log filename is not changed)
* kill -HUP <pid>
* smbcontrol <pid> reload-config
This commit removes 3 calls of is_default_dyn_LOGFILEBASE() to make sure that:
- 1st removal: child uses log.wb-<name> after the fork
- 2nd removal: child after HUP signal, does not switch to log.winbindd
- 3rd removal: child after smbcontrol reload-config, does not switch to
log.winbindd

In samba3 it is possible to run some services externally, for example:
rpc_daemon:lsasd = fork
rpc_server:netlogon = disabled
rpc_server:samr = external
rpc_server:lsarpc = external
The external services running in separate processes have to use its own
dedicated ncalrpc endpoint, otherwise will race with main smbd serving the
embedded services to accept connections on ncalrpc default socket. If the
connection ends in an external process and the client tries to bind to an
interface not registered there (like winreg for example) the bind will fail.

Handle the case where a NT4 DC does not fill in the acct_flags in
the samlogon reply info3. Yes, in 2021, there are still admins
arround with real NT4 DCs.
NT4 DCs reject authentication with workstation accounts with
NT_STATUS_NOLOGON_WORKSTATION_TRUST_ACCOUNT, even if
MSV1_0_ALLOW_WORKSTATION_TRUST_ACCOUNT is specified.
We no longer call dcerpc_samr_QueryUserInfo(level=16)
to get the acct_flags, as we only ever got
ACB_NORMAL back (maybe with ACB_PWNOEXP in addition),
which is easy to calculate on our own.

winbind: remove legacy flags fallback
Some very old NT4 DCs might have not returned the account flags filled in. This
shouldn't be a problem anymore. Additionally, on a typical domain member server,
this request is (and can only be) send to the primary domain, so this will not
work with accounts from trusted domains.

It means one more caller of the problematic cm_connect_sam()
function is removed! SAMR connections may not be allowed for
machine accounts with modern AD DCs.
For network logons NT4 DCs also skip the
account_name, so we have to fallback to the
one given by the client. We have code to cope
with that deeply hidden inside of netsamlogon_cache_store().
Up to Samba 4.7 netsamlogon_cache_store() operated on the
info3 structure that was passed to the caller of winbind_dual_SamLogon()
and pass propagated up to auth_winbind in smbd.
But for Samba 4.8 the following commit:
