0.10

New features / API changes:

• Add Eio.Process for cross-platform subprocess support (@patricoferris @talex5 #499, reviewed by @anmonteiro @avsm @haesbaert).

• Add Eio_unix.Net module (@talex5 #516, reviewed by @avsm).
  The Unix network APIs have been cleaned up and moved here, and some missing datagram operations have been added.
  send now takes an iovec, not just a single buffer.

• Add support for domain local await (@polytypic @talex5 #494 #503).
  Allows sharing e.g. kcas data-structures across Eio and Domainslib domains.

• Add initial eio_windows backend (@patricoferris @talex5 #497 #530 #511 #523 #509, reviewed by @avsm @polytypic).

• Remove eio_luv backend (@talex5 #485).
  It was only used on Windows, and has been replaced by eio_windows.

• Unify Eio_linux.FD and Eio_posix.Fd as Eio_unix.Fd (@talex5 #491).
  Now that eio_luv is gone, there is no need for different backends to have different types for wrapped file descriptors.

• Move Eio.Stdenv.t to Eio_unix.Stdenv.base (@talex5 #498).
  Note that the rest of Eio.Stdenv is still there; only the definition of a full Unix-like environment has moved.

• Deprecation cleanups (@talex5 #508).
  Removed some APIs that were already marked as deprecated in Eio 0.8.

Bug fixes:

• eio_linux: fall back to fork if clone3 is unavailable (@talex5 #524, reported by @smondet, reviewed by @avsm).
  Docker's default security policy blocks clone3.

• Don't call accept_fork's error handler on cancellation (@talex5 #520).
  This isn't an error and should not be reported.

• Fix eio_unix_is_blocking C stub (@patricoferris #505, reviewed by @talex5).

• Fix Condition.await bug when cancelling (@polytypic @talex5 #487).

• eio_posix: probe for existence of some flags (@talex5 #507, reported by @hannesm).
  FreeBSD 12 didn't have O_DSYNC. Also, add O_RESOLVE_BENEATH and O_PATH if available.
