[LTP] LTP realtime tests

[Petr Vorel]

Hi RT folks,

looking into LTP realtime tests (testcases/realtime/ [1]),
the code certainly deserves cleanup.

Looking at [2], it does not mention these tests at all.
Can anyone comment on relevance of these tests to current RT?
Does anyone use these tests?

Thanks for feedback.

Kind regards,
Petr
