I have converted all .gz and .bz2 files to .xz on download.qemu.org
and this patch would change the links in the website.  This would save
about 5 GB of bandwidth every day (about 20% savings).

xz should be available for all platforms.  Besides providing better
compression ratios, decompression of .xz files is about twice as fast
compared to bzip2.  Compression instead is about 5.5 times slower.
