RTEMS untar implementation had problems with overwriting or integrating archives into existing directory structures. This patch adapts the behavior to mimic that of a GNU tar or BSD tar and extends the tar01 test to check for the behavior. That is: * If a directory structure exists, the files from the archive will be integrated. Existing files are overwritten. * If a file exists and the archive contains a directory with the same name, the file is removed and a directory is created. In the above example: if l1/l2 is a file it will be overwritten with a new directory. * If a directory exists and the archive contains a file with the same name, the directory will be replaced if it is empty. If it contains files, the result is an error. * An archive also can contain only a file without the parent directories. If in that case one of the parent directories exists as a file extracting the archive results in an error. In the example: if l1/l2 is a file and the archive doesn't contain the directories but only the file l1/l2/x.txt that would be an error. * In case of an error, it is possible that the archive has been partially extracted. Closes #4568
