Ignore EPIPE when writing, since it means we've shut down and don't need a wake-up (the event has presumably already been processed).

Also, ignore EAGAIN and EWOULDBLOCK. If the pipe is full, then a wake-up is already pending.

CHANGES:

New features / API changes:

- Replace objects with variants (@talex5 @patricoferris ocaml-multicore/eio#553 ocaml-multicore/eio#605 ocaml-multicore/eio#608, reviewed by @avsm).
  Some potential users found object types confusing, so we now use an alternative scheme for OS resources.
  For users of the resources, the only thing that changes is the types:

  - Instead of taking an argument of type `#foo`, you should now take `_ foo`.
  - Instead of returning a value of type `foo`, you should now return `foo_ty Eio.Resource.t`.

  To provide your own implementation of an interface, you now provide a module rather than an object.
  For example, to provide your own source flow, use `Eio.Flow.Pi.source (module My_source)`.

  If you want to define your own interfaces, see the `Eio.Resource` module documentation.

- Add `Eio.Pool` (@talex5 @darrenldl ocaml-multicore/eio#602, reviewed by @patricoferris).
  A lock-free pool of resources. This is similar to `Lwt_pool`.

- Add `Eio.Lazy` (@talex5 ocaml-multicore/eio#609, reviewed by @SGrondin).
  If one fiber tries to force a lazy value while another is already doing it,
  this will wait for the first one to finish rather than raising an exception (as `Stdlib.Lazy` does).

- Add `Eio.Path.native` (@talex5 ocaml-multicore/eio#603, reviewed by @patricoferris).
  This is useful when interacting with non-Eio libraries, for spawning sub-processes, and for displaying paths to users.

- Add `Flow.single_write` (@talex5 ocaml-multicore/eio#598).

- Add `Eio.Flow.Pi.simple_copy` (@talex5 ocaml-multicore/eio#611).
  Provides an easy way to implement the `copy` operation when making your own sink.

- Eio_unix: add FD passing (@talex5 ocaml-multicore/eio#522).
  Allows opening a file and passing the handle over a Unix-domain socket.

- Add `Process.run ?is_success` to control definition of success (@SGrondin ocaml-multicore/eio#586, reviewed by @talex5).

- Add `Eio_mock.Domain_manager` (@talex5 ocaml-multicore/eio#610).
  This mock domain manager runs everything in a single domain, allowing tests to remain deterministic.

- Add `Eio.Debug.with_trace_prefix` (@talex5 ocaml-multicore/eio#610).
  Allows prefixing all `traceln` output. The mock domain manager uses this to indicate which fake domain is running.

Bug fixes:

- Fork actions must not allocate (@talex5 ocaml-multicore/eio#593).
  When using multiple domains, child processes could get stuck if they forked while another domain held the malloc lock.

- eio_posix: ignore some errors writing to the wake-up pipe (@talex5 ocaml-multicore/eio#600).
  If the pipe is full or closed, the wake-up should simply be ignored.

Build/test fixes:

- Fix some MDX problems on Windows (@polytypic ocaml-multicore/eio#597).

- The README depends on kcas (@talex5 ocaml-multicore/eio#606).

- Clarify configuration for lib_eio_linux and enable tests on other arches (@dra27 ocaml-multicore/eio#592).

- eio_linux tests: skip fixed buffer test if not available (@talex5 ocaml-multicore/eio#604).

- eio_windows: update available line to win32 (@talex5 ocaml-multicore/eio#588 ocaml-multicore/eio#591).
