* fhandler_random.cc (fhandler_dev_random::crypt_gen_random):

Browse Source 
Use CryptAcquireContextW.
	* ntdll.h (STATUS_PROCEDURE_NOT_FOUND): Define.
	* sec_auth.cc (open_local_policy): Rename NTSTATUS variable ret to
	status.  Drop usage of LsaNtStatusToWinError.
	(verify_token): Call NtQuerySecurityObject instead of
	GetKernelObjectSecurity.
	(create_token): Rename NTSTATUS variable ret to status.  Rename ret2 to
	sub_status.  Drop usage of LsaNtStatusToWinError.  In case LsaLogonUser
	fails, report the sub_status as well.
