Don't let the column balancer calculate sizes that don't fit.

If the initial balancing pass calculated a block-size that wasn't enough
to fit everything, stretch the columns, but not beyond what we have room
for in any outer fragmentation context.

Part of this fix is the realization that we cannot reliably tell up
front that we are going to need more outer fragmentatainers or not (if
block-size is auto); hence the rename from needs_more_fragments_in_outer
to bool allow_more_fragments_in_outer.
