2a17fbe88a sulogin: use bb_error_msg instead of bb_info_msg; better message

Let's say explicitly what we are doing: we are giving user a shell
(presumably to do some maintenance in single-user mode).

265a74b983 Kbuild: move CONFIG_PAM to general configuration 
Currently CONFIG_PAM depends on CONFIG_LOGIN, but is used by the httpd applet too.

This patch moves said option to general configuration, thus allowing to
compile httpd with PAM support independently from login.

b6dc13c2d3 sulogin: allow system maintenance login if root password is empty 
The current password checking is unable to distinguish between the user
entering an empty password or pressing Control-D. As a result, an empty
password always results in normal startup.

We modify bb_ask to return NULL if Control-D is pressed without entering
a password. The sulogin applet is then modified to only proceed to
normal startup if bb_ask returns NULL. This covers EOF with no password,
interrupt by timeout and ^C.
