Clean up net unit testing code.

- Move code included from blah_unittest.h (where blah_unittest.cc has actual
  unittests) into their own files, often completely out-of-lining the
  definitions.
- Remove anonymous namespaces from headers.
- Reorder method declarations.
- Make other unit test link against net_test_support instead of reaching in and
  including .h files in their targets directly.
