* tests: consolidate redundant, duplicated helper code These functions currently exist in a sourced shell library, but there is an identical copy of them in a single test file. Get rid of this duplicate definition. * tests: mark some tests as skipped if bc is not installed `exit 77` is the GNU exitcode protocol for tests that cannot be run because their prerequisites are not available. If `bc` is not installed, and it often isn't, the test can be short-circuited instead of failing; meson will report them in "warning yellow". * tests: mark some tests as skipped if support is not compiled Not all test cases can be cleanly marked as skipped -- sometimes, multiple things are checked, and having one be unavailable should not mean skipping all tests. But in a couple cases, a test file only tests one thing, and that may be skipped. In such cases, it can be semantically indicated in the test harness report collection, that a skip occurred.
