Subject[PATCH 09/16] zlib-decompression-status.diff

Shows some stars during decompression. This is particularly useful on
old 386s where one asterisk is probably printed every second - making
the long linux and initramfs uncompress progress more evident.

Not compile tested outside {i386, x86_64} - don't have other machines.
