ReFrame now differentiates its exit codes as follows:

• 0: success (as before)
• 1: any error that is not one of the following (partially as before)
• 2: command-line misuse (partially as before - only errors directly issued by the argument parser followed this convention; now all command-line usage errors exit with 2)
• 3: sanity failure error: at least one test failed in sanity
• 4: performance failure error: all failed tests failed in performance

Closes #2306.
