[WIP] Replace gzip/bzip2/xz with pigz/pbzip2/pxz for multicore enviro…

…nment This PR is to fix issue #113. And It can be used as an alternative of PR #117. In modern generation, most of the developers are using a machine based on multi-core architecture. From now on, Let's prepare to support parallelism. pigz is compatible with the existing gzip because pigz is using gzip's library. pbzip2 is compatible with the existing pbzip2 because pbzip2 is using bzip2's library. pxz is compatible with the existing xz because pxz is using xz's library.
