Various post AuthRewrite cleanups, fixups and tidyups.

Zero out some of the plaintext passwords for paranoia

Fix up some of the other passdb backends with the change to *uid_t rather than
uid_t.

Make some of the code in srv_netlog_nt.c clearer, is passing an array around,
so pass its lenght in is definition, not as a seperate paramater.

Use sizeof() rather than magic numbers, it makes things easier to read.

Cope with a PAM authenticated user who is not in /etc/passwd - currently by
saying NO_SUCH_USER, but this can change in future.
