locitest: generate tests from the test_data files
The "c" section of the test data file should allocate and populate a LOCI
object. The resulting wire buffer is compared to the "binary" section.
This only tests serialization, but given that we have autogenerated tests that
round-trip each object I think this is sufficient.
I added C sections to the OF 1.0 test data files. OF 1.3 tests will come in a
future pull request.
