a8461173ba decompress_uncompress: comment out debug printout on corrupted data 
99% plus of all people who'll get corrupted archive wouldn't bother

c71547ccfc decompress_uncompress: move 'code' variable into loop - sole user 
Apparently, gcc does this optimization itself, since generated code is the same.

8a6a2f9c9c update seamless uncompression code 
This change makes "tar tf hello_world.txz" work without
adding special-casing for ".txz" extension. It also removes
ever-growing magic checking code in rpm2cpio and get_header_tar -
we reuse one which lives in setup_unzip_on_fd.
