r13524: Add -t|--password-from-stdin option to pdbedit as we had with Samba 2.2.

This fixes bug #1386.

The initial changes had been made by Carsten Höger <choeger at
open-xhange dot com> for Samba 2.2 while being at SuSE. *sigh*

To not duplicate code from smbpasswd in pdbedit stdin_new_passwd() and
get_pass() are moved from smbpasswd to utils/passwd_util.c.
(This used to be commit dbdc5ba497c6010dbad47c9d77fc8bec5557a328)
