Refs: #8871

This PR is an experiment which hopefully mitigates #8871.

Moves zlib initialization to the point of execution on worker thread pool. This allows to postpone the corresponding memory allocation (the computation) to a later point in time which may be critical in situations when many zlib streams are created and operated simultaneously.

The following script leads to 2.7GB RSS on my machine with the latest master:

const zlib = require('zlib');

const message = {
  some: "data"
};
const payload = Buffer.from(JSON.stringify(message));

for (let i = 0; i < 30000; ++i) {
  zlib.deflate(payload, () => { });
}

setTimeout(() => { }, 2000000);

With the proposed changes, the RSS becomes around 200MB.

18:55:09   1.40 false positives, when considering a   5% risk acceptance (*, **, ***),
18:55:09   0.28 false positives, when considering a   1% risk acceptance (**, ***),

@addaleax I've found that ResetStream() and SetParams() need to be called with properly initialized zlib. I have addressed that in 3e1c4833896d097fafeaf2668de7a054f9cb1162 and improved tests, so that they verify these changes. Please let me know if you see any issues in the update.

I got a successful CI run, so formally this PR is mergeable. But as it's an experiment, I'd like to gather more opinions on this change.

Hope you guys don't mind me asking, but is there a timeline for getting this merged? The zlib fragmentation issue is impacting our application ;(

Hello, are there any plans to bring this fix over to the current LTS (Node 12)?

@RosenTomov I wasn't planning to backport it, at least until I get some evidences that this patch mitigates the memory fragmentation issue for some users. Can you confirm that v14.7.0 mitigates the issue for you?
