b5d6ae9a33 Don't compile get_header_tar_FOO function if they are not needed 
Now get_header_tar_gz, get_header_tar_bz2, get_header_tar_lzma
are only used if dpkg is built.

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.

b76f18d331 Improve unzip's handling of stream ZIP files 
Search harder for the ZIP magic numbers at the end of a file by checking
16 KiB from the end instead of just 1 KiB.  ZIP files with long comments
(such as certain cryptographically signed files) or those sitting in a
wrapper could have more than 1 KiB of data after the magic numbers, so
they couldn't be read.
