client: Move builder stuff into a separate object

This is messy as hell. I moved so much stuff around and lost track of
most of it. So this is a commit to kind of have some baseline.

The BIO interface is large and very well suited to encode larger

therefore will spend a long time on setting up and destroying the BIO

These low-level functions are a lot faster and easier to set up.

nothing that we need to access at any time. Therefore the fields have
