Brian Goff d68cc0e8d0 plugin: closer-based plugin notification socket ... This changes things to rely on a plugin server that manages all connections made to the server. An optional handler can be passed into the server when the caller wants to do extra things with the connection. It is the caller's responsibility to close the server. When the server is closed, first all existing connections are closed (and new connections are prevented). Now the signal loop only needs to close the server and not deal with `net.Conn`'s directly (or double-indirects as the case was before this change). The socket, when present in the filesystem, is no longer unlinked eagerly, as reconnections require it to be present for the lifecycle of the plugin server.
