Migrate to kselftest harness. Use a fixture test with enclave initialized
and de-initialized for each of the existing three tests, in other words:

1. One FIXTURE() for managing the enclave life-cycle.
2. Three TEST_F()'s, one for each test case.

These changes make it easier to add tests and I think it is a valuable
addition.


This gives a leaps better reporting than before. Here's an example

The output claims to conform to TAP13 but it does not seem as though all of
the output conforms to TAP13. I assume such output would confuse automated
systems.

You mean

0x0000000000000000 0x0000000000002000 0x03
0x0000000000002000 0x0000000000001000 0x05

?

Yes
