Add context recursion tests.

- 1.0 expand:
  - e003 looked like e002.  Made it use a level of indirection.
- 1.1 expand:
  - Copy e002 and e003 to e052 and e053 and use newer "context
    overflow" code.
  - Add e054 cross linked sibling contexts test.
  - Add 0124, 0125, 0126 scoped context recursion tests.
