[v2] - rebase on top of previous arguments posted to the list - introduces zlib compression - introduces zstd compression
Please help if you know anything about zstd/zlib compression. This puts compression on top of multifd. Advantages about current compression: - We copy all pages in a single packet and then compress the whole thing. - We reuse the compression stream for all the packets sent through the same channel. - We can select nocomp/zlib/zstd levels of compression. Please, review.
