Subject: [PATCH] covscan: remove unused vars, mark private func static, return values
The `begin` and `end` variables were not used
in `ModulePackageContainer::updateFailSafeData`. Removed.
The `checksum` in "utils.cpp" is a private (static) function.
Added check of return value of `dnf_copy_recursive` function in unit test.
In the `install` in the "goal-py.cpp" file:
Explicitly ignores the return values of `hy_goal_install` and
`hy_goal_install_optional`. The functions always return zero.
Explicitly ignores the return values of `hy_goal_install_selector` and
`hy_goal_install_selector_optional`. The `error` argument is used instead.
