Generic implementation of a VPP node processing four buffers at a time in a feature arc

Safety

• The preconditions of the GenericFeatureNodeX1::map_buffer_to_next & GenericFeatureNodeX4::map_buffer_to_next_x4 methods must be upheld.
• Nodes with this node as a next node must send valid buffer indices in the Vector data.
• This mode must be invoked as part of a feature arc.
• All of the next nodes of this node must have a Vector type of BufferIndex, Scalar of () and Aux of () (or their C equivalents).
