* Fix idempotency for Unix permissions in zip files.
This fix prevents the unarchive module from reporting 'changed' when a zipfile contains items with Unix permissions that differ from the system default.
* Update zip unarchive tests.
Additional tests for the unarchive module with zip files:
- Test file in zip archive with non-default permissions
- Test file added to zip archive with Windows permissions
* Additional fix for mixed win/unix archives.
Turns out my original fix fails under some mixed archives, as setting the umask to zero can be applied to those files. This creates a per-file umask variable, so a mix of permission types don't cause problems.
* CI Checks
CI checks for archives with:
* non default Unix permissions
* Windows permissions
* Workaround for BSD differences.
Using Zipinfo due to lack of support in BSD unzip.
Permissions handling is also different in BSD -- always applies UMASK to file permissions.
* Added checks for creating directories and SSH keys for existing users.
This change corrects problems reported by the `yamllint` linter.
Since key duplication problems were removed in 4d48711, this commit
mainly fixes trailing spaces and extra empty lines at beginning/end of
files.
