PAM issues

If you use pam 1.3 and pambase 20200721 you might not be able to login due to
a missing pam_faillock.so module. Make sure you are using pam 1.4 when using
pambase 20200721.

If you upgrade to pam 1.4 you might experience all kind of weird login problems.

You might also get `pam_systemd(login:session): Failed to create session: Input/output error`
in your log and just hanging text console logins.

You can also get sporadic ssh logins with an sshd going 100% CPU and never letting
you log in.

Any manual configuration changes in the pam modules have to be checked
carefully before upgrading, some modules have gone (like pam_tally2, cracklib).

Also make sure to merge your .pacnew/.pacsave files.

In case you experience similar problems you can also downgrade to:
- pambase-20190105.1-2.0 and
- pam-1.3.1-2.0 (for pentium4) resp.
  pam-1.3.1-2.0 (for i686) resp.
  pam-1.3.1-2.0 (for i486).
