If I understand the xz format correctly, its nearly identical to lzma,
and the 'xz' utility can decompress .lzma files too.  Any chance the xz
code you're adding can be used to handle lzma-compressed archives?  If
so, can we deprecate CONFIG_LZMA and have the new CONFIG_XZ support
handle both .xz and .lzma archives?  Or at least share a significant
chunk of code between the two formats?

Best,
Peter
