Minor corrections in terms of readability and performance

[MarchMore]

Fixed implicit casts to bool. Replaced "auto" with "auto*" for readability. Added "noexcept" to move constructor and move assignment operator at c_raii class.

I wasn't aware of this one. Reverted corresponding code.

Thanks! I like the two noexcepts and will add those separately in another commit I'm doing, should land in the next push.
