[arch-dev-public] [signoff] libarchive 2.6.0

Hey guys, Looking for a signoff for libarchive 2.6.0. I had to apply one small patch to fix a problem I found running pactest on the pacman source, so it is fairly well-tested already. On another note- I compiled *without* LZMA support, which is now available as of this release. I would like to eventually compile this in, but it would require us to move the lzma-utils package to core. Any big objections to moving this in so libarchive can be compiled with LZMA support? -Dan
