Subject: [PATCH] ssl: replace size/1 by xxx_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. However, <c>byte_size/1</c> also
accepts a bitstring (rounding up size to a whole number of bytes), so
one must make sure that the call to <c>byte_size/</c> is preceded by a
call to <c>is_binary/1</c> to ensure that bitstrings are rejected. Note
that the compiler removes redundant calls to <c>is_binary/1</c>, so if
one is not sure whether previous code had made sure that the argument is
a binary, it does not harm to add an <c>is_binary/1</c> test immediately
before the call to <c>byte_size/1</c>.
