CHANGES:

• Add support for UDP (@patricoferris #171).

• Rename Fibre to Fiber (@talex5 #195). This is to match the compiler's spelling.

• Switch to luv backend if uring can't be used (@talex5 #203).
  Useful on Windows with WSL, and also in Docker containers on older systems.

• Eio_linux: cope with lack of fixed chunks (@talex5 #200).

  • If we run out of fixed memory, just use regular memory instead of waiting (which might deadlock).
  • If we try to allocate a fixed buffer and fail, we now just log a warning and continue without one.

• Add support for FD passing with Eio_linux (@talex5 #199).

• Add Eio_unix.FD.as_socket (@talex5 #193).
  Useful for working with existing libraries that provide a Unix.file_descr, or for receiving FDs from elsewhere (e.g. socket activation).
  Also, the Luv.{File,Handle}.of_luv functions now allow controlling whether to close the wrapped FD.

• Add Eio_unix.sleep (@talex5 #188). Based on feedback that some people don't want to treat time as a capability. Possibly also useful for debugging race conditions.

• Tidy up forking API (@talex5 #192). Moves some common code out the the individual backends.

• Improve documentation (@talex5 #197 #194 #186 #185). In particular, explain more low-level details about how cancellation works.

• Add an example Eio_null backend (@talex5 #189). This supports creating fibers, promises and cancellation, but provides no IO operations.

• Effect.eff is now Effect.t in OCaml trunk (@talex5 #201).
