2e6ca274a4 Fix challenge types in poly::multiopen and poly::commitment 
The argument to the poly::commitment prover and verifier was mistakenly
represented as a challenge, when in fact the commitments may be opened at
any scalar (which just happens to be a challenge within poly::multiopen).

The poly::commitment APIs are now public again.

f63f3ff2af Introduce typed challenge scalars 
This also centralises the challenge generation logic in Challenge::get,
ensuring it is consistent across the codebase.
