Originally opened as m-labs/nmigen-soc#3

This arbiter should be compatible with all the optional features of wishbone.Interface.

The round-robin implementation could perhaps be moved to nmigen.lib and imported back here, but that would make nmigen-soc depend on a later revision than nmigen v0.1.

jfng included the following code: https://github.com/m-labs/nmigen-soc/pull/3/commits
