[Libvir] Use of getpass

[Richard W.M. Jones]

We recently added a call to getpass(3) function.  Needless to say this 
doesn't exist on Windows.  More seriously the man-page for getpass on 
Linux has strong exhortations not to use the function.

NAME
        getpass - get a password

SYNOPSIS
        #include <unistd.h>

        char *getpass( const char * prompt );

DESCRIPTION
        This function is obsolete.  Do not use it.

        The  getpass() function opens /dev/tty (the controlling terminal 
of the
        process), outputs the string prompt, turns off echoing, reads 
one  line
        (the  "password"),  restores  the  terminal  state  and closes 
/dev/tty
        again.
[...]
CONFORMING TO
        Present in SUSv2, but marked LEGACY.  Removed in POSIX.1-2001.

Should we remove it?  Replace it?

Rich.
