I don't see the need for these defines. WINE_LINKMON_ADDRCHANGE could be turned into a function.

Using a generic socket object might work I guess. The cost will be a new socket per caller whereas in theory we could serve all callers with a single socket, though that would require a dedicated server request. That might be needed anyway, if this handle somehow turns out to be special.
I know MacOS has a similar socket based mechanism that could probably be handled in the same way.
