This reduces repeated code significantly, and allows for easier
supervision of what's being grouped to the suites + possibly what
timeouts apply.
Note that some artificial test case identifiers (in check_array.c,
check_log.c, check_loop.c, check_rb.c, check_utils.c) got changed
so they now follow 1:1 the test (function) name that is being run
for the case at hand without the "test_" prefix (strict convention).
Exception to this are test_ipc_disp_* tests in check_ipc.c that got,
conversely, changed to test_ipc_dispatch_* to follow the test case
identifiers.
