Avoid creating two variable names referring to the same memory
area, because that can cause aliasing warnings in some versions of
gcc.

The io_list_len() function returns an int, where a negative return
value indicates a type error. One problem is that an int only consists
of 32 bits in a 64-bit emulator. Changing the return type to Sint
will solve that problem, but in the 32-bit emulator, a large iolist
and a iolist with a type error will both return a negative number.
(Noticed by Jon Meredith.)
Another problem is that for iolists whose total size exceed the
word size, the result would be truncated, leading to a subsequent
buffer overflow and emulator crash.
Therefore, introduce the new erts_iolist_size() function which
returns a status indication and writes the result size through
a passed pointer. If the result size does not fit in a word,
return an overflow indication.

io_list_vec_len() is slightly more general than it needs to be.
Specifically:
* The only caller always passes ERL_SMALL_IO_BIN_LIMIT as the
value for the bin_limit parameter, so the bin_limit parameter
can be eliminated.
* The only caller never passes any NULL pointers, so there is
no need test the pointers before writing through them.

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.

In older releases of Erlang/OTP, the '=:=' operator could run out
of stack if used to compare very deep lists. Since that problem
has been fixed, we can remove the workaround used in the deep/1
test case.
