testsuite: Improve test setup output and add test summary for spectest

[rdmark]

• Gives a more helpful stdout response when mandatory options are missing.
• Turn on color output by default, and flip the effect of the -C option.
• Refactor the test result functions, and add global test counting.
• Print a test results summary for the spectest.
• Remove the Quirk mode and add a nondeterminism skip criteria instead.
• Print __func__ when running a test module, effectively removing the old page number references.
• Standardize a few test app option letters.
• Move test302 from tier1 to tier2 spectest, where it passes.
