2018-06-20Re-work some more c_str() usage.Tom Sepez
Many of these are converting ByteString => c_str => ByteStringView, since the ByteStringView ctor is implicit. This is unfortunate, since that involves a strlen() which the ByteString already knows if we use AsStringView() instead. This changed one test result where we can now return the string "\0" instead of "" -- since strlen no longer eats the NUL. This seems consistent, say, with String.fromCharCode().
