Retitle to "compress/zlib: support xform and stream creation"
About stateful, since it looks like it is not supported for the moment,
I think stream_create/stream_free functions should fail or should not be implemented.
More comments inline.

I don't think this is the suitable value for dynamic compression.
Z_HUFFMAN_ONLY does not do LZ77. I think the strategy for this case is Z_DEFAULT_STRATEGY.

As said in other email, you can directly get the mempool pointer from internals.

This can be in the same line.

This can be written like "return zlib_pmd_stream_create(...);

Fix indentation here.
