Migrated the bulk of the feature-specific tests

Browse Source 
This involved some minor tweaks for the various types of tests, added
predicates to the test framework (necessary for test_entries and
test_alloc), and cleaned up some of the testing semantics such as
reporting how many tests are filtered, showing permutation config on
the result screen, and properly inheriting suite config in cases.
