[Bug 1951943] Re: Engine crashes when loading the configuration more than once

[Julian Andres Klode]

** Description changed:

  [Impact]
  
   * Engine crashes when loading the configuration more than once
  
   * Upstream started to avoid loading engines twice by using dynamic ids
  to track the loaded engines correctly
  
   * OpenSSL 3
  https://github.com/openssl/openssl/commit/81c11349c2a0e945aa3dfc6bd81c957363dd2011 (bugfix)
  https://github.com/openssl/openssl/commit/38e2957249c90317a26a080c7e7eb186dd5b6598 (test case)
  
   * OpenSSL 1.1.1 backports:
  https://github.com/openssl/openssl/commit/9b06ebb1edfddffea083ba36090af7eb7cad207b (bugfix)
  https://github.com/openssl/openssl/pull/17083 (test case)
  
  [Test Plan]
  
   * https://github.com/openssl/openssl/issues/17023 lists multiple ways
  how one can trigger the issue at hand, but also test case implements
  this issue too by explicitly attempting to load an engine multiple times
  and checking that it is operational.
  
- The test is run during the build as part of the upstream regression test
- suite
+ The test are unfortunately *SKIPPED* during the build as part of the
+ upstream regression test suite
  
  [Where problems could occur]
  
   * Separately we have started to fix userspace packages that needlessly
  load configuration files multiple times, which used to trigger this
  issue. The codepaths changed are with engine use, how they are
  loaded/unloaded/used. It is possible that this fix will make some
  engines to start working and be used resulting in new behaviour. But
  also exposing bugs in the engines that previously were installed &
  configured but not actually used.
