Subject: [PATCH 1/2] crypto: replace size/1 by byte_size/1

The <c>size/1</c> BIF is not optimized by the JIT, and its use can
result in worse types for Dialyzer.

When one knows that the value being tested must be a tuple,
<c>tuple_size/1</c> should always be preferred.

When one knows that the value being tested must be a binary,
<c>byte_size/1</c> should be preferred.
