Gzip: compatibility with recent zlib-ng versions. It now uses custom alloc_aligned() wrapper for all allocations, therefore all allocations are larger than expected by (64 + sizeof(void*)). Further, they are seen as allocations of 1 element. Relevant calculations were adjusted to reflect this, and state allocation is now protected with a flag to avoid misinterpreting other allocations as the zlib deflate_state allocation. Further, it no longer forces window bits to 13 on compression level 1, so the comment was adjusted to reflect this.
