Comment (by Olly Betts):

 We can't just move `ReplicateTcpClient` and link it only into `xapian-
 replicate` because it uses `RemoteConnection` so we'd need to expose that
 in the library ABI instead.  Similarly for `ReplicateTcpServer`.

 I tried this and then had to move various other things around and add ABI
 visibility to `TcpClient` as well as `RemoteConnection`.

 In exchange, I removed ABI visibility from `ReplicateTcpClient`,
 `ReplicateTcpServer` and `TcpServer`.

 I need to check if this is actually a win in terms of symbols in the ABI.
 `TcpClient` is just a single method in a namespace (so one symbol) but
 `RemoteConnection` has quite a lot of methods.

 Maybe more refactoring could establish a cleaner split point.
