This will happen if we ^D at the Login: prompt without having provided a
valid login before.
Set pwd to NULL on bad login attempts to prevent audit_logout() from being
called for a user which didn't actually log on.

"login_prompt". This makes more sense than "prompt" which is what
login actually used, so change the code to match the documentation.

it complains that it can't do it because the filesystem is readonly.
Assume that when the user has a readonly /dev that they don't care if
login can't change the permissions/flags. While this does break a few
things like msgs, we'll assume that the user setting up the read only
system knows what they are doing.
All this change does is to stop the complaint when the file system is
read only. It also adds comments as to why EROFS and EOPNOTSUPP are
ignored.
This allows one to have a read-only / w/o a /dev MFS and have a
relatively warning-free existence. /etc/rc still complains when it
can't chown/chflags/chmod things, but that's easy to ignore/tweak.

2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

However, there's still a bug in login.c
because you copy the environment *before* the call to pam_open_session,
which won't set the necessary variables set by /usr/ports/security/pam_ssh.
