[PATCH v3 0/2] MR9835: Server: Add wrapper for debug and error output

[Ralf Habacker (＠rhabacker)]

While working on !7650, it turned out that the logs generated by wineserver do not use a prefix, which makes it difficult to distinguish the corresponding entries in combined logs e.g. `WINEDEBUG=+file,+winsock,+server` from the other debug channels. This is fixed by this merge request.
