list_drop_empty

<code>list_drop_empty()</code> removes empty elements from a list. This includes <code>NULL</code>
elements along with empty vectors, like <code>integer(0)</code>. This is equivalent to,
but faster than, <code>vec_slice(x, list_sizes(x) != 0L)</code>.

Defines new notions of prototype and size that are used to
provide tools for consistent and well-founded type-coercion and
size-recycling, and are in turn connected to ideas of type- and
size-stability useful for analysing function interfaces.
