[igt-dev] [PATCH i-g-t v3 1/2] scripts/verify-blacklist: Script for checking blacklist files

[Petri Latvala]

tests/intel-ci/blacklist*.txt files can collect bitrot unless there's
an easy way to check for lines that are no longer needed due to the
tests being renamed or removed. Therefore, a script just for that.

v2: Use long options for readability, exit with 1 if something found

v3: Verify manually against the list of all tests instead of trying
    with igt_runner's --include-tests
