F21 System Wide Change: lbzip2 as default bzip2 implementation

Is there enough of a gain to the system to only partially replace a core
program like this (especially with alternatives)?  This seems like a
case where either we get a "new and improved and replaces the old"
version (where the new one just obsoletes the old one, such as the
jpeg-turbo change), or just leave it alone.

Please understand, I don't mean to "attack" you or your code.  I just
think adding a second implementation of a core utility like bzip2 is a
bad idea unless there is a significant gain.  If there's a point where
lbzip2 can fully replace bzip2 (so all CLI and API uses), and there are
good benefits, then Fedora should just replace the old implementation
with a new one.
