removing code no longer needed now that file listings are not stored in info files and db. I may not find time to do this change on the 4.6 branch, but the change as it's just removal of dead code.
Deprecating apm_version_file_list and making it use apm_get_package_files. Deprecating db_package_supports_rdbms_p (use apm_package_supports_rdbms_p instead). Removing debug printouts
