rust-chg: add function to send fds via domain socket

As a beginning, I wrote some C.

It's extracted from attachio() of contrib/chg/hgclient.c. Maybe it could
be rewritten in Rust by using the libc (and/or nix) crates, but doing that
wouldn't be trivial as the code depends on CMSG_*() macros. IMO, using C
is better here.

#if no-windows no-osx

  $ mkdir -p xdgconf/hg
  $ echo '[ui]' > xdgconf/hg/hgrc
  $ echo 'username = foobar' >> xdgconf/hg/hgrc
  $ XDG_CONFIG_HOME="`pwd`/xdgconf" ; export XDG_CONFIG_HOME
  $ unset HGRCPATH
  $ hg config ui.username 2>/dev/null
  foobar

#endif
