container: Move pending state to state struct

Browse source 
Pending state is currently inlined directly in the container struct,
while the current state is in a state struct. A side-effect of this is
that it is not immediately obvious that pending double-buffered state is
accessed, nor is it obvious what state is double-buffered.

Instead, use the state struct for both current and pending.
