possible to add non lz compressors #21

Since there's no google group sounding it out here.
Might be nice to add a few more compressors (that aren't lz) just in the theory that "more data is good!" or what not. Though I know it goes against the name and scope of the project :)

(ex: zpaq, bsc, whatever else squash has that lzbench doesn't)

Thanks for the benchmarks! :)

Sure it can be done but it requires a support from open-source community.

Out of curiosity, there is no actual technical limitations to adding non-LZ compressors, right? The project description somehow lists the types of compressors included, but I assume that's just kind of a loose filter with the idea of including the "faster" end of the compressing spectrum. If you had a compressor that wasn't LZ but performed well (especially if better than some existing included ones), would @inikep allow it it be included?

Sure, I will allow commits with non-LZ compressors. But I may leave them disabled by default if there will be some compilation issues. For example, I had some problems with auto-disabling glza (requires gcc 4.9+) and LZSSE (requires SSE).

I happened to add bzip2 codec to the lzbench. It is pretty standard compressor so I thought it deserves attention.
I didn't do a commit - git is a bit magical to me but I made a patch to the newest version if anyone is interested. Maybe it fill find a place in the bench.
