iolist_size/1: Fix truncation of result
iolist_size/1 would silently return a truncated result for iolists
whose size exceeded the word size. For example:
iolist(lists:duplicate(256, <<0:(1 bsl 24)/unit:8>>)).
would return 0 (instead of 4294967296 or 1 bsl 32).
Rewrite iolist_size/1 to accumulate the size in a bignum if
necessary and result the correct result.
