Add AbortSignal support to stream.finished
This PR adds support for AbortSignal in stream.finished (eos).

Originally, I thought about adding it to the promisified version only, however I think that it could be useful to both.

I've implemented it so that if the stream is already closed, and the AbortSignal is also aborted, the closed gets prioritised (no error is emitted).

  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • tests and/or benchmarks are included
  • documentation is changed or added
  • commit message follows commit guidelines

I'm not convinced by this change - I might expect for the stream to be destroyed on abort. What's the rationale for not doing so?

IMO finished is more of a passive listener than a stream controller. It doesn't really do anything except add listeners on the underlying stream (It's also in the description A function to get notified when a stream is no longer readable, writable or has experienced an error or a premature close event). The cleanup function that (already) returns from finished also doesn't destroy the underlying stream.

However, maybe aborting should invoke the cleanup function (which it currently doesn't).

If finished does not destroy the stream, then pipeline will?

Yes. The way I see it pipeline has "non recoverable side effects" on the stream and should destroy while finished has no side effects and should not destroy.
