Remove "Z" constant for binary strings

We've started using magic comments to ensure any strings we
create are binary instead.  Additionally, ensure we create any
StringIO objects with an explicit string (which default to
binary) to ensure the StringIO object is binary.  This is
because StringIO.new (with no arguments) will always use the
process-wide default encoding since it does not know about
magic comments (and couldn't, really...)
