* Revert PR #3575 since it causes problems related to exclude patterns
By using a different method for getting archive filelists, and extracting we introduced new problems related to excluding based on gtar patterns.
As a result files that would be excluded by gtar, would still be in the filelist. Implementing our own gtar compatible pattern exclusion mechanism is near to impossible (believe me, we looked at it...). The best way is to look at the original problem and deal with that, and ensure that extraction and filelists are done with the exact same tool and exact same options.
The solution is to decode the octal unicode representation in gtar's output back to unicode. Since gtar has no problem extracting these files in LANG=C, we simply has to compensate for it.
This reverts #3575 and fixes#11348.
* Implement codecs.escape_decode() instead of decode("string_escape") for python3
