This is a low level function that should not ignore results.
If the caller doesn't care it's his choice.

Like netlogon_creds_cli_delete, protected by netlogon_creds_cli_lck
instead of netlogon_creds_cli_lock.

This adds an external locking scheme to protect our
netlogon_creds_CredentialState. This is needed because the routines
exposed by netlogon_creds_cli.h need a more flexible locking to
set up our credentials in a properly protected way.

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.

This way the caller can pass more than 2 hashes and can only
know which hash was used for a successful connection.
We allow up to 4 hashes (next, current, old, older).

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).
(further patches still need to address forcing a RWDC contact)

I have been building 4.2.0 with the GNU C compiler but I decided to see
how it works with the Sun C 5.11 compiler. The Sun compiler complains
about a identifier being redeclared in libcli/auth/netlogon_creds_cli.c

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:
