• 2709: Bats test refactoring for CHECK constraints

• 769: Fixed a bug (just introduced) in resolving default column expressions
  Unbreaks dolt
  The reason that this bug didn't break the in-memory implementation is it keeps its column defaults reified as Expressions, so it doesn't really use most of the related analyzer machinery
• 762: Refactored how grant tables are stored
  This refactors a lot of previously-written code to more manageably handle future modifications to the grant tables, and to ease their use and reduce potential development mistakes.
