Generate streaming operators for std::ostream

[trittsv]

It is a common task to somehow log the received samples.
For this std::ostream streaming operators are needed which are currently (v0.10.4) not generated from the .idl files.
Other Vendors do also generate streaming operators, for cyclone we have to manually create them currently.

So every datatype shall have a streaming operator.

Examples

// Stream all class members
std::ostream& operator<<(std::ostream& s, T_TextMarkupSupportedType const& rhs)
{
    return s << "["
             << "A_boldSupported: " << (rhs.A_boldSupported())
             << ", A_italicSupported: " << (rhs.A_italicSupported())
             << ", A_strikethroughSupported: " << (rhs.A_strikethroughSupported())
             << ", A_highlightSupported: " << (rhs.A_highlightSupported())
             << ", A_boldAndItalicSupported: " << (rhs.A_boldAndItalicSupported())
             << ", A_specialCharactersSupported: " << (rhs.A_specialCharactersSupported())
             << "]";
}

// Stream enums
std::ostream& operator<<(std::ostream& s, T_HorizontalAlignmentType const& rhs)
{
    switch (rhs)
    {
        case P_Display_Extension_PSM::T_HorizontalAlignmentType::L_HorizontalAlignment__Invalid:
            s << "T_HorizontalAlignmentType::L_HorizontalAlignment__Invalid"; break;
        case P_Display_Extension_PSM::T_HorizontalAlignmentType::L_HorizontalAlignment__Default:
            s << "T_HorizontalAlignmentType::L_HorizontalAlignment__Default"; break;
        case P_Display_Extension_PSM::T_HorizontalAlignmentType::L_HorizontalAlignment__Left:
            s << "T_HorizontalAlignmentType::L_HorizontalAlignment__Left"; break;
        case P_Display_Extension_PSM::T_HorizontalAlignmentType::L_HorizontalAlignment__Centre:
            s << "T_HorizontalAlignmentType::L_HorizontalAlignment__Centre"; break;
        case P_Display_Extension_PSM::T_HorizontalAlignmentType::L_HorizontalAlignment__Right:
            s << "T_HorizontalAlignmentType::L_HorizontalAlignment__Right"; break;
        default: break;
    }
    return s;
}

I think it is a worthwhile thing to generate these, and it is quite straightforward, too. Unfortunately, I don't think I'll get around to it anytime soon, but perhaps someone else feels up to the challenge?

I will implement it 🙂

Hi @eboasson its implemented and the PR #472 is ready for review.
Would be great if you could have a look into it 😃
