3e72a12daf netlogon_creds_cli: Add netlogon_creds_cli_lck
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.

4b97de8adb rpc_client3: Avoid "cli_credentials" in cli_rpc_pipe_open_schannel_with_creds
This provides cleaner data dependencies. A netlogon_creds_ctx contains
everything required to open an schannel, there is no good reason to

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 :-()

first struct element is again a struct. I'm lost. 25 years of C coding and I
have no clue of the language :-(
