NFC. Add comment about debugserver usage

This just adds a comment to SocketAddress about it being used by debugserver and the implications of that.

If we need to make changes to this class that make it unsuitable for debugserver we can re-implement the minimal abstractions we need from this file in debugserver. I would prefer not to do that because code duplication is bad. Nuff said.
