Dave Collins c065733c31 multi: Improvements to configurable checkpoints. ...

This contains a bit of cleanup and additional logic to improve the
recently-added ability to specify additional checkpoints via the
--addcheckpoint option.

In particular:
- Improve error messages in the checkpoint parsing
- Correct the mergeCheckpoints function to weed out duplicate height
  checkpoints while using the most-recently provided one as described by
  its comment
- Add an assertion to blockchain.New that the provided checkpoints are
  sorted as required
- Keep comments to 80 columns and use two spaces after periods in them to
  be consistent with the rest of the code base
- Make the entry in doc.go match the actual btcd -h output
