Closes #1304

PR disables C++ unit tests for libdnf5, libdnf5-cli, dnf5 cpr_plugin C++. These unit tests use private symbols that are no longer accesible. It is a temporarily solution until the unit tests are modified.

attribute((visibility())) is a compiler-specific extension. E.g. GCC and Clang have them. Other compilers might not have. Consider guarding the definition with GNUC preprocessor condition.

I did a rebase to resolve the conflicts.

There is some issue with loading builddep plugin: Cannot load dnf5 plugins: builddep_cmd_plugin.so. Though it rather seems like an issue with some older build from this PR as the version is 5.2.1.0-1.20240521115637370466.pr1307.37.g0cb81683.fc41. Maybe you would have to create a new PR, I've also encountered something similar recently. It was a Packit-related issue. It could be the same problem here.

Thanks, looks good. Just a rebase is probably needed to fix tests.

The Locker class has been moved to the public API in upstream.
So, I did a rebase and modification of this PR.

The current tests issues are connected with the new rpm 4.19.91-6 in Rawhide. A subsequent update 4.19.91-7 should fix the issues (tested locally). Waiting to get into compose and we can re-run the tests...

Sorry about that, but could you rebase again please? From the other PRs, it seems that the CI is finally working again...

dnf5 app, dnf5 plugins: Do not export private symbols

@jrohel
Do not export symbols from private "/common/utils"
7a86447 
Libraries and applications (libdnf5.so, dnf5, dnf5daemon-client...) use
(and statically link) private utilities from "/common/utils".
And they also publicly export the symbols of these private utilities.

This modification hides the symbols of utilities linked from
"/common/utils".

PR that adds the API (rpm-software-management#1452)
was merged right before rpm-software-management#1307
so its missing there.
