Large Commitfest items

There has been some discussion around excluding large items from the
current commitfest, for several reasons. However I don't recall ever
seeing a definition of a large item. It seems to be a bit like "I know
it when I see it."   I've been looking at the current commitfest
entries. Based on that I suggest a heuristic that says a commitfest
item with patches greater than 5000 lines is large.

That's around 20 items in the current commitfest. I think we need to
be able to use some discretion to allow items with more lines or
exclude items with less lines that nevertheless have far-reaching
impacts, but this seems like a reasonable starting point.

We could double that number by reducing the 5000 to 2000, but that
seems too restrictive to me.

Thoughts?

cheers
