simpler wire protocol for multiplexing connections or streams into a single connection, based on a subset of qmux.
qmux-lite is the qmux protocol without the window flow-control mechanism. This makes it much easier to implement while still working in situations where flow-control is less necessary (local IPC, in-memory). A qmux-lite implementation can easily be upgraded to qmux by adding the removed window related messages and flow-control mechanism.
