We had a mix of struct declarations followed by typedefs, and direct
struct definitions as part of a typedef. Pick a single style. Also
float forward declarations of opaque types to the top of the file,
rather than interspersed with function declarations, which will help a
future patch that wants to expose yet another opaque type that will be
referenced in NBDRequest. No semantic impact.
