changing to no longer read/write file listings and database support from/to info files. This info is now determined directly from the paths in the file system (see procs apm_get_package_files and apm_package_supports_rdbms_p)
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
