Hi Jarkko,

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.

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

TAP version 13
1..3

ok 1 enclave.unclobbered_vdso

ok 2 enclave.clobbered_vdso

ok 3 enclave.clobbered_vdso_and_user_function

v5:
* Use TH_LOG() for printing enclave address ranges instead of printf(),
based on Reinette's remark.

Thank you for considering my feedback. The motivation for my comment was to consider how this test output will be parsed. If these tests will have their output parsed by automated systems then it needs to conform to the TAP13 format as supported by kselftest.

In your latest version the output printed during a successful test has been changed, using TH_LOG() as you noted. From what I can tell this is the only output addressed - failing tests continue to print error messages (perror, fprintf) without consideration of how they will be parsed. My apologies, I am not a kselftest expert to know what the best way for this integration is.
