characters except for the chksum field which is treated as if
it was filled with spaces. According to the GNU tar sources,
some tars (Sun and NeXT) calculate chksum with signed char,
which will be different if there are chars in the buffer with
the high bit set. So we calculate two checksums, unsigned and
signed.

Zy)_Streama Class that serves as an adapter between TarFile and
a stream-like object. The stream-like object only
needs to have a read() or write() method that works with bytes,
and the method is accessed blockwise.
Use of gzip or bzip2 compression is possible.
A stream-like object could be for example: sys.stdin.buffer,
sys.stdout.buffer, a socket, a tape device etc.
_Stream is intended to be used only internally.

a! Add the file `name' to the archive. `name' may be any type of file
(directory, fifo, symbolic link, etc.). If given, `arcname'
specifies an alternative name for the file in the archive.
Directories are added recursively by default. This can be avoided by
setting `recursive' to False. `filter' is a function
that expects a TarInfo object argument and returns the changed
TarInfo object, if it returns None the TarInfo object will be
excluded from the archive.

a Extract all members from the archive to the current working
directory and set owner, modification time and permissions on
directories afterwards. `path' specifies a different directory
to extract to. `members' is optional and must be a subset of the
list returned by getmembers(). If `numeric_owner` is True, only
the numbers for user/group names are used and not the names.
The `filter` function will be called on each member just
before extraction.
It can return a changed TarInfo or None to skip the member.
String names of common filters are accepted.
