The tar -x command in busybox does not restore the file mode correctly.

The reason is most probably this code in
archival/libunarachive/data_extract_all.c:

       chmod(file_header->name, file_header->mode);
       chown(file_header->name, file_header->uid, file_header->gid);

chown clears the set*id bits (on current versions of linux :). Flipping
the order around fixes the problem.

(tested with 1.00pre3 from cvs).

87af49f26b If a tar entry is a regualr file ending in a '/' then its really a
directory.
From http://www.gnu.org/manual/tar/html_node/tar_123.html
REGTYPE
AREGTYPE
    These flags represent a regular file. In order to be compatible with
older versions of tar, a typeflag value of AREGTYPE should be silently
recognized as a regular file. New archives should be created using
REGTYPE. Also, for backward compatibility, tar treats a regular file
whose name ends with a slash as a directory.

91e464632b Fix bug when handling debian packages.
If we read the contents of compressed files within the ar archive,
e.g. control.tar.gz, then file position gets all out of whack, so
it has to be reset before reading thenext header.
