Validate keywords that combine schemas with various logical operators.
Also add iterators over schemas. Now we only need them to skip some
tests, but later they will come in handy for non-test code.

This CL implements validation for the "type", "enum" and "const"
keywords.
Validation in its full generality requires that references in the schema
be resolved. We put that off for now; it isn't needed for most simple
keywords.
The JSON Schema folks provide an extensive test suite for validation at
https://github.com/json-schema-org/JSON-Schema-Test-Suite. We use it for
our tests, copying the necessary files into testdata. The files aren't
perfectly independent; for example, one test in enum.json requires the
"properties" keyword, which we haven't done yet. We will excise those
tests via calls to t.Skip as they arise.
