The switch is useful to ensure that any fibers waiting for a flush are cancelled on error. However, it's not essential, and whatever cancelled the writer will probably cancel the flushing fibers too anyway. This makes it easier to create buffers outside of the eio event loop and is useful when porting existing code from Faraday. Also, expose the `abort` function and the `Flush_aborted` exception, so that callers can clean up manually.

CHANGES: New features: - Add `Eio.Condition` (@TheLortex @talex5 ocaml-multicore/eio#277). Allows a fiber to wait for some condition to become true. - Add `Eio.Net.getaddrinfo` and `getnameinfo` (@bikallem @talex5 ocaml-multicore/eio#278 ocaml-multicore/eio#288 ocaml-multicore/eio#291). Convert between host names and addresses. - Add `Eio.Debug` (@talex5 ocaml-multicore/eio#276). Currently, this allows overriding the `traceln` function. - `Buf_write.create`: make switch optional (@talex5 ocaml-multicore/eio#283). This makes things easier for people porting code from Faraday. Bug fixes: - Allow sharing of libuv poll handles (@patricoferris @talex5 ocaml-multicore/eio#279). Luv doesn't allow two callers to watch the same file handle, so we need to handle that in Eio. Other changes: - Upgrade to uring 0.4 (@talex5 ocaml-multicore/eio#290). - Mention `Mutex`, `Semaphore` and `Condition` in the README (@talex5 ocaml-multicore/eio#281).
