[new release] eio (5 packages) (0.14)

CHANGES:

New features / API changes:

- Add `Eio.Executor_pool` (@SGrondin ocaml-multicore/eio#639, reviewed by @talex5).
  Provides an easy way to distribute jobs across domains.

- Add `Fiber.first ~combine` and `Fiber.n_any` (@SGrondin @talex5 ocaml-multicore/eio#587).
  Allows keeping both results in the case where multiple fibers succeed.

- Add `Eio_mock.Backend.run_full` with auto-advancing mock clock (@talex5 ocaml-multicore/eio#644, reviewed by @SGrondin).
  Simplifies testing of code using clocks.

- Add `Buf_write.printf` (@SGrondin @talex5 ocaml-multicore/eio#655).

- Add `Net.listening_addr` (@mefyl ocaml-multicore/eio#555, reviewed by @patricoferris @talex5).
  Useful to get the socket's address if the OS assigns it.

- Add `Promise.try_resolve` (@talex5 ocaml-multicore/eio#646).

- Remove `Cancel_hook_failed` exception (@talex5 ocaml-multicore/eio#640).
  Didn't seem to be used and broke dscheck.

Tracing:

- Improve tracing (@TheLortex @patricoferris @talex5 ocaml-multicore/eio#656).
  Trace cancellation contexts and OS operations, and simplify API.

- Add labels to switches (@talex5 ocaml-multicore/eio#661, reviewed by @SGrondin).

- `Fiber.all`: use the parent fiber (@talex5 ocaml-multicore/eio#665, reviewed by @SGrondin).
  Cleans up the traces a bit.

Performance:

- Faster and simpler `Lf_queue` (@talex5 ocaml-multicore/eio#647, based on work by @polytypic).

- Optimise `Flow.copy` with `Buf_read.as_flow` (@talex5 ocaml-multicore/eio#663, reviewed by @SGrondin, reported by @leostera).

Bug fixes:

- Fix handling of very long IO vectors (@talex5 ocaml-multicore/eio#653, reported by @Cjen1).

- eio_posix: use `caml_enter_blocking_section` in more places (@talex5 ocaml-multicore/eio#654, reviewed by @SGrondin).

- eio_posix: work around `caml_unix_alloc_sockaddr` bug (@talex5 ocaml-multicore/eio#651).

- Remove default backtrace from `Switch.fail` (@talex5 ocaml-multicore/eio#664).

Documentation:

- Organise eio.mli better (@talex5 ocaml-multicore/eio#667).

- Fix quoting of quotes in process error messages (@talex5 ocaml-multicore/eio#666, reviewed by @SGrondin).

- Mention Path module in File and Fs documentation (@talex5 ocaml-multicore/eio#659, requested by @clecat).

- Minor documentation updates (@SGrondin @talex5 ocaml-multicore/eio#670).

Build / internals:

- Allow closing synchronous streams (@talex5 ocaml-multicore/eio#641, reviewed by @SGrondin).
  This isn't currently exposed in the public interface.

- Fix non-idempotent tests (@SGrondin ocaml-multicore/eio#662).

- eio_windows: add explicit fmt dependency (@talex5 ocaml-multicore/eio#643).
