Tamer Tas d852ae6f2b [testrunner] remove recursive result calls in chain processors
Procs return the result by increasing recursion through result_for.

This CL eliminates that mechanism from the Processor interface and uses boolen
return values for sending tests to signal success or the failure to load the
test into the execution queue.
