Don't implicitly TALLOC_FREE(creds) in the pure store routine. This
mixes up responsibilities, and there's not enough callers to justify
the TALLOC_FREE to be centralized.

Same number of .text bytes, but simpler code.
Yes, this is {{0}} instead of {0}, which I always promote. I've just read a
comment on stackoverflow (which I've unfortunately just closed the tab for :-()
that {{0}} might actually be the correct way to init a struct to zero if the
first struct element is again a struct. I'm lost. 25 years of C coding and I
have no clue of the language :-(

This allows you to forward bad password count resets to 0. Currently,
there is a missing access check for the RODC to ensure it only applies
to cached users (msDS-Allowed-Password-Replication-Group).

If the NETLOGON response was an error e.g. NT_STATUS_NOT_IMPLEMENTED, any subsequent
calls failed with NT_STATUS_ACCESS_DENIED. This is likely to be the cause of RODC DNS

Until all callers are fixed to pass the same 'server_computer'
value, we try to calculate a server_netbios_name and use this
as unique identifier for a specific domain controller.
Otherwise winbind would use 'hostname.example.com'
while 'net rpc testjoin' would use 'HOSTNAME',
which leads to 2 records in netlogon_creds_cli.tdb
for the same domain controller.
Once all callers are fixed we can think about reverting this
commit.

This provides an abstraction to hide netlogon_creds_CredentialState,
which is stored in a node local tdb.
Where the global state (netlogon_creds_CredentialState) between client and
server was only kept in memory (on the client side), we now use
the abstracted netlogon_creds_cli_context.
We now use a node specific computer name in order to establish
individual netlogon sessions per node.
If the caller wants to use some netlogon calls with credential chain
(struct netr_Authenticator), netlogon_creds_cli_lock*() is used
to get the current netlogon_creds_CredentialState in a g_lock'ed
fashion, a talloc_free() will release the lock.
The locking is needed as there might be more than one process
(multiple winbindd child, cmdline tools) which want to talk
to a specific domain controller. The usage of netlogon_creds_CredentialState
needs to be serialized as it uses sequence numbers.
LogonSamLogonEx doesn't use the credential chain, but for some operations
it needs the global session in order to de/encrypt individual fields.
It uses the lockless netlogon_creds_cli_get() and netlogon_creds_cli_validate()
functions, which just make sure the session hasn't changed between
get and validate.
This is prepares the proper fix for a large number of bugs:
