This commit adds a batchingConn interface, and renames batchingUDPConn to linuxBatchingConn. tryUpgradeToBatchingConn() may return a platform- specific implementation of batchingConn. So far only a Linux implementation of this interface exists, but this refactor is being done in anticipation of a Windows implementation.
