cyrus-sasl-bdb-2.1.28-160000.2.2

- Use %patch -P N instead of deprecated %patchN.

- Fix build with RPM 4.19: unnumbered patches are no longer
  supported.

- Add _multibuild to define 2nd spec file as additional flavor.
  Eliminates the need for source package links in OBS.

- drop optional opie dependency

- Do not set directories inside doc/ mode 644; otherwise the
  directories are set 644 as well, which means no files inside are
  accessible. This resulted in the past in doc/ actually not being
  added to the devel package.

- update to 2.1.28 (bsc#1196036, CVE-2022-24407):
  * https://www.cyrusimap.org/sasl/sasl/release-notes/2.1/index.html#new-in-2-1-28
- drop cyrus-sasl-bug587.patch (upstream)

- cyrus-sasl: prevent fail of %pre when berkely db utils are
  not installed (seems like we want to use this only for upgrade
  so no Prereq added)
- move license to licensedir
- remove use of RPM_BUILD_ROOT
- minimal spec cleanups
- avoid bashisms

- postfix: sasl authentication with password fails (bsc#1194265)
  Add config parameter --with-dblib=gdbm
- Avoid converting of /etc/sasldb2 by every update. Convert
  /etc/sasldb2 only if it is a Berkeley DB

- Fix build: Do not build libsasl2-3 in the bdb package. This will
  not be linked to berkely db. libsasl2-3 is now defined as
  %BuildRequires and %Requires

- CVE-2020-8032: cyrus-sasl: Local privilege escalation to root
  due to insecure tmp file usage. (bsc#1180669)
  Use /var/adm/update-scripts/ instead of /tmp. Clean up temporary
  files.
