PAPI Counter Validation Tests

My PAPI validation tests have been merged into the PAPI development tree and will be included with the PAPI 6.0 release. Older versions of the tests can be found here:

Deterministic Counter Validation

I've done some work attempting to validate the various deterministic performance counters on a variety of systems. More on this will follow.

Valgrind

It would be nice to be able to use DBI tools when doing such validations. I like using Valgrind, but various instructions aren't supported.

Here's my reminder list of those that need to be implemented:
