We also have LTP_ENABLE_DEBUG that has the same values so let's keep the
API the same. I've send v3 with this and the docs changes.

I've only added the docs for LTP_REPRODUCIBLE_OUTPUT in v3, the sorting
should go in a separate patch. We also miss at least TST_ENABLE_DEBUG in
the output of -h switch as well.
