Hi everyone

Here's version 3 of this set, with some tidy-ups suggested by Jacopo,
so thanks for those!

In my earlier replies I had suggested changing the way we refer to AGC
channels, using names rather than numbers. However, much of that work
would go into the previous "AGC multi-channel" patch set, which I see
has now been merged!

So I propose dealing with all that later, and merging this patch set
before we make any of those changes. Hope that's OK?

Thanks
David
