This is subtle, since the assignment to |this.deviceStates| is ~60 lines down.
Would it be worthwhile to factor out some helper methods for setting up
newDeviceStates, newNetworkStateLists, and newActiveNetworkStates from the
blocks below?

I actually have a CL that cleans this up some. It doesn't really help with
efficiency (which is what I was aiming for), but is probably worth committing as
a cleanup CL. Stay tuned :)
