many changes relating to session construction and audioengine interaction

every session member is now initialized using C++ constructor syntax

session construction reordered to clarify the split(s) between work
where the engine is not relevant and work where is it is. this
split is still not 100% obvious, but is enormously clearer than
previously.

if engine/backend are not running as session is created, and the SR
of the sample rate is known, attempt to force backend to that value.
