flex_array: flex_array_prealloc takes a number of elements, not an end
commit 5d30b10bd68df007e7ae21e77d1e0ce184b53040 upstream.
Change flex_array_prealloc to take the number of elements for which space
should be allocated instead of the last (inclusive) element. Users
and documentation are updated accordingly. flex_arrays got introduced before
they had users. When folks started using it, they ended up needing a
different API than was coded up originally. This swaps over to the API that
folks apparently need.
