ifndef USE_PAM.
* lib/prototypes.h: Remove the declaration of add_cons_grps(). The
function does not exist.
* libmisc/age.c (setup_uid_gid): is_console is never set ifndef
USE_PAM. Change the prototype of setup_uid_gid() when USE_PAM is
not defined. This permits to remove add_groups from PAM builds.
setup_uid_gid is already subject to HAVE_INITGROUPS.
* libmisc/pwd2spwd.c (pwd_to_spwd): pwd_to_spwd() is not used in
PAM builds.
src/passwd.c, src/pwck.c, src/pwconv.c, src/useradd.c,
src/usermod.c: On Jan 01, 1970, do not set the sp_lstchg field to
0 (which means that the password shall be changed during the next
login), but use -1 (password aging disabled).
* src/passwd.c: Do not check sp_min if sp_lstchg is null or -1.
