Reduce checkpoints' effect on consensus.
Instead of only checking height to decide whether to disable script checks, actually check whether a block is an ancestor of a checkpoint, up to which headers have been validated. This means that we don't have to prevent accepting a side branch anymore - it will be safe, just less fast to do. We still need to prevent being fed a multitude of low-difficulty headers filling up our memory. The mechanism for that is unchanged for now: once a checkpoint is reached with headers, no headers chain branching off before that point are allowed anymore.
