lib: Pass qosspec at flow allocation

The flow allocator now passes the full qos specification to the
endpoint, instead of just a cube. This is a more flexible
architecture, as it makes QoS cubes internal to the layers.

Adds endianness transforms for the flow allocator protocol in the
normal IPCP.
