If we have vendored the capnp package, we want to get the OCaml schema compiler plugin binary from there, not from `$PATH`.

…c-unix (0.4.0) CHANGES: Breaking changes: - Wrap errors with the `` `Capnp`` tag to make it easier to compose with other types of error (mirage/capnp-rpc#172, mirage/capnp-rpc#173). - Prefix all command-line options with `capnp-` (mirage/capnp-rpc#163). e.g. `--listen-address` is now `--capnp-listen-address`. The old names were confusing for applications that supported other protocols too (e.g. a web server). New features: - Add `Capability.with_ref` convenience function (mirage/capnp-rpc#170). This automatically calls `dec_ref` when done. - Add Unix `Cap_file` module to load and save `Sturdy_refs` (mirage/capnp-rpc#165). In particular, this ensures that saved cap files get a mode of `0o600`, since they contain secrets. - Export cmdliner network address parsing (mirage/capnp-rpc#165). This is useful if you don't want to use the default option parsing. For example, if you want to make Cap'n Proto an optional feature of your program. - Upgrade from `uint` (which is deprecated) to the newer `stdint` (mirage/capnp-rpc#166, mirage/capnp-rpc#168). The latest version of `uint` is just a wrapper around `stdint`, so this shouldn't break anything if you are using the latest version. - Put cmdliner options in their own man-page section (mirage/capnp-rpc#163). Use `Capnp_rpc_unix.manpage_capnp_options` to control where in your man-page they appear. - Enable `SO_KEEPALIVE` for TCP connections (mirage/capnp-rpc#167). For use with Docker's libnetwork, try something like this in your `stack.yml`: ``` sysctls: - 'net.ipv4.tcp_keepalive_time=60' ``` Bug fixes: - Close listening socket when shutting down a vat (mirage/capnp-rpc#171). - Don't mark secret keys as executable (mirage/capnp-rpc#164). - Update README example to use dune (mirage/capnp-rpc#162). Build changes: - Replace topkg with dune-release (mirage/capnp-rpc#169) - Update opam email address and fix missing bound (mirage/capnp-rpc#161). - Update the `dune` files to allow duniverse / vendored builds (mirage/capnp-rpc#165). - Fix the crossed-calls unit test (mirage/capnp-rpc#171). - Force all capnp-rpc subpackages to have the same version (mirage/capnp-rpc#173).
