Libuv: Release proposal: v1.40.0

[cjihrig]

I'd like to release v1.40.0 this week. Please let me know if you have any concerns.

Notable changes:

• The UV_UDP_MMSG_FREE flag has been added.
• UV__EPROTO has been remapped from 4046 to -4046 for consistency with other error codes.
• On Windows, UTF-16 surrogate pairs are no longer replaced with the Unicode replacement character.
• uv_timer_get_due_in() has been added.

Is there any chance #2951 can get in? 🙏

As long as no one requests other changes in that PR, I'll land it in time for the release.

The libuv CI seems fine: https://ci.nodejs.org/view/libuv/job/libuv-test-commit/2067/

However, the Node.js integration CI is broken on Windows (https://ci.nodejs.org/view/libuv/job/libuv-in-node/164/, https://ci.nodejs.org/view/libuv/job/libuv-in-node/166/, https://ci.nodejs.org/view/libuv/job/libuv-in-node/167/). It looks like the culprit for that is, at a minimum, https://github.com/libuv/libuv/pull/2979.

Untested, but I think https://github.com/libuv/libuv/pull/3003 should fix the Node.js test failures.

Node integration CI: https://ci.nodejs.org/view/libuv/job/libuv-in-node/168/

Both are green, so I'm planning to move forward with the release.
