This is a major structural cleanup. It extracts the complex logic for checking socket status, finding a CLOSED socket, and forcibly closing CLOSING sockets into a separate helper function (findAvailableSocket). This eliminates all goto statements in socketBegin and socketBeginMulticast, greatly improving readability and maintainability.
