Are the throws handled anywhere and can they be replaced with regular {:error, _} returns?

This should only throw due to programmer error. It doesn't make sense to take a balance of delegate. It makes even less sens to get foreign_offchain_account_balance when ChannelStatePeer is for delegate.

We use this functions only in places where it's know the ChannelStatePeer.role is not delegate.

Good code, some small typos.

By default no additional options should be passed for update validation.
