Subject: [PATCH] test/test-lib.sh: use $test_subtest_name in all tests

Set the variable '$test_subtest_name' in all functions which starts
a new test and use that variable in all functions that output
test results.

Additionally output the latest '$test_subtest_name' in case of
abnormal exit, to avoid confusion.
