b596335868 tar: correctly skip (and warn about) pax headers. 
plug memory leak. save 50 bytes.
Wooohooo! we finally can unpack kernel tarballs!

7725d0ff5c tar: add support for FEATURE_TAR_GNU_EXTENSIONS so than we can save 
long names now. We were able to read such tars, but not create.
+275 bytes. Without FEATURE_TAR_GNU_EXTENSIONS: -25 bytes.

We still cannot unpack Linux kernels, but not for long ;)

d6772501db tar: fix and sanitize handling of long filenames/linknames 
(GNU extensions 'K' and 'L').
We correctly handle them when untarring now, but unfortunately
we still don't use them when tarring! That stupid 100 char limit
is still there!
The biggest problem is that we don't support 'pax' tar format.
Linux kernel tarballs are in this format... shame

* pack: mask mode with 07777

67b23e6043 getopt_ulflags -> getopt32. 
It is impossible to formulate sane ABI based on
size of ulong because it can be 32-bit or 64-bit.
Basically it means that you cannot portably use
more that 32 option chars in one call anyway...
Make it explicit.

64d7e93081 - convert a few xopen3(,,0) into xopen(,). Also peruse the fact that xopen defaults to 0777 on it's own, so we don't need to xopen3(,,0777). 
Saves a few bytes:

1bfca7bac7 Cleanup headers and replace the zero padding with an even smaller version. 
One of the pads turned out to be unnecessary: sizeof(struct TarHeader) is
TAR_BLOCK_SIZE, the padding's in the struct.  The others could be done inline
with bb_common_bufsiz1.

This is a cleanup I did to Denis' patch long ago, but got sidetracked by
what turned into svn 15660.

9cac521f07 using [xa]sprintf for string concatenation is neat and saves 
~100 bytes according to bloatcheck. Also this fixes bug in rpm
