"enum class" has more advantages than "enum" because it's strongly typed and scoped.

I suggest removing the IDNA_ prefix from the members of idna_mode since the scope is changing. For example, idna_mode::IDNA_STRICT should just be idna_mode::STRICT.

@tniessen BTW, I have one question about test. For now, Build Windows and Coverage Windows are failed, but I don't know why these tests are failed. It's very helpful if you let me know how I can resolve this case.
