Merge #647

647: merge socket constants r=Susurrus

> Refactor the constant declarations such that all constants are only declared once with a #[cfg] that only enables the constant on the correct platforms.

Closes #637 

(same PR as #646 but from another branch, to see if buildbot has a problem with PR made from master branch)

+### Added
+- Added protocol families in `AddressFamily` enum.
+  ([#647](https://github.com/nix-rust/nix/pull/647))
+
 ### Changed
 - Renamed existing `ptrace` wrappers to encourage namespacing ([#692](https://github.com/nix-rust/nix/pull/692))
+- Changed function signature of `socket()` and `socketpair()`. The `protocol` argument
+  has changed type from `c_int` to `SockProtocol`.
+  It accepts a `None` value for default protocol that was specified with zero using `c_int`.
