* autoload.cc: Make autoloaded ntdll function non-optional. Ditto for 

secur32 functions, except for LsaRegisterLogonProcess.  Change return
	value to ERROR_PROC_NOT_FOUND.  Explain why.
	* sec_auth.cc (lsaauth): Handle ERROR_PROC_NOT_FOUND from call to
	LsaRegisterLogonProcess when generating the errno value.
