* Early return authenticate if TLS smartcard logon
* Removed obsolete SmartcardPin and unified AuthenticateEx calls
* Remove password-is-pin from command line
The setting is implied by smartcard-logon and only of interest in
server side code, so the setting is useless
* Rework AUTH_SMARTCARD_PIN
Just prompt for PIN and not user/domain if this is requested.
* Fixed a memory leak in nla.c
* Align credentail prompt
* Handle AUTH_NLA & smartcard, just ask for PIN
* Added assertions, removed duplicate password prompt check
* Move smartcard logon after credential prompt
