Moving pr_* debug macros to have it with in same object as debug variables, becase we will change them to use verbose variable in next patch.

* sample_id_all bit. Without the sample_id_all bit, non-sample events (such as
|
|
* mmap events) do not have an id sample appended, and consequently logic
|
|
* designed to determine the id will not work. That case happens when there is

* more than one selected event, so this test processes three events: 2
|
|
* attributes representing the selected events and one mmap event.
|
|
*
|
|
* Return: %0 on success, %-1 if the test fails.
