Fragment channel handler types into multiple small files

[richardkiss]

I did a small amount of group because the number of tiny structs was so overwhelming. I did it mostly by things similarly named, which is a tad naïve. Be open to moving things around a bit more, or fragmenting into smaller bits.

• [nitpick] The error message 'no default setup' is vague and may not provide enough context for debugging. Consider using a more descriptive error message that specifies which default setup is missing.
