Nit: List friends atop the private: section.

It might be better in this case to go ahead and expose a getter.  I'm not
obsessed with keeping |providers_| secret.

Okay, created a providers() getter; removed the friend declaration.

I made const ACProviders*.  (I don't want it to return a const ACProviders
itself because that would make a copy.)  If you want me to make it return a
const ACProviders& instead, I can easily do that.
