All,
     The attached patch cleans up a few minor problems in the bzip2/lzma
decompression support, pointed out by Jiri in internal review.  In
particular, it fixes a possible memory leak on realloc() error, it fixes
a shifting typo, and it changes the xc_dom_printf()'s to be a bit clearly
about which compression routine is in-use.

Developed and tested against the RHEL-5 tools, but applies without fuzz
to the xen-unstable tools.
