I merged this patch, but not the others. I also dropped one functional
change:

That "+ 1" didn't really belong here, since everything else was just renaming a
field. Such a patch shouldn't make any other changes.

There were also three more occurrences of min_buffers_needed (one in a comment,
two in a vivid function argument), and I renamed those as well.

'git grep min_buffers_needed' now no longer shows any hits.

I decided not to take the other patches, I think it is best if you rebase
and repost the series on top of staging and in the new year we'll continue with
it. I did not feel that I had enough time to really review the remaining patches.

However, it is nice to have this large rename patch merged. It touches on a lot
of files, so it is annoying to have to carry that around. And now was a good
moment to merge it.

Regards,

	Hans
