* Makefile.in, configure.in, chkpwd.c, acconfig.h: support for
`chkpwd', a setuid helper program for machines which use shadow
passwords (configure --enable-chkpwd)
* Makefile.in, configure.in, auth.c, citadel.pam, user_ops.c: support
for PAM or shadow passwords (configure --with-pam)
* Makefile.in: made some messages simpler
* citadel.spec: updated for 5.53; correct name of tarball; build with
--enable-chkpwd and --with-pam; add defattr tags so rpm's can be
built by non-root user
* commands.c: cosmetic cleanup
* config.c: (security/paranoia) check permissions on citadel.config
