The code to verify user and password provided in

daemon/verify-{crypt,shadow}.c prints out the user name in various
places, where daemon/verify-pam.c code does not. Get out of sync with
the login dialog, and you'll have your password logged.

Adapt patches from the gdm 2.20 branch for
(1) not logging the user name in any syslog error messages
(2) not localizing the log messages.

Fixes PR 31417.
