The style-bot is going to choke on this patch, but it's literally just moving functions to different files.

I have seen more NeverDestroyed<> used more often than DEFINE_STATIC_LOCAL() recently. Do you know if there is a reason for using one or the other?

Nit: m_sourceBuffers won't change length during the loop so you can cache length() in a variable during initialization.

Ditto.

I don't.  But we can change these in a future patch.
