support for zopfli gzip archives about createrepo_c HOT 5 OPEN

I think switching to zlib-ng (which is much faster, thus allowing you to use a more aggressive profile and still get better performance) or an alternate format such as zstd would be far superior options, at this point.

Those libraries would also provide some decompression speed benefits as well. Zopfli only helps with compression.

That works for me

Worth closing in favor of #82 ?

The major advantage of zopfli is that it has a gzip compatible output stream. Exiting tooling can benefit from the enhanced compression without changes. The zstd format is a great one, but requires client side tooling updates.

I'm told that DNF has supported it for a few years (since roughly EL 8.2 & Fedora 30) which means the only gap is on the repo-metadata-generation side. Of course EL7 won't have that option, but looking forward it's not as much of a concern - and in any case EL7 prefers sqlite metadata if available which uses BZ2 compression by default.
