ci: Add lcov configuration to ignore g_return_if_fail()/g_assert() While we can’t add markers to the macro implementations to cause lcov to ignore them automatically, we can change our lcov configuration to ignore all calls to them. See https://github.com/linux-test-project/lcov/issues/44. This causes all the un-takeable branches and un-reachable assertions to be ignored by our code coverage, which bumps our statistics: • Lines: 74.9% → 74.8% • Functions: 82.3% → 82.3% • Branches: 53.3% → 64.2% The rationale is that nobody should be testing programmer error handling, as g_return_*if_fail() are used to guard against — so it’s not reasonable to count missed branches like that in code coverage statistics.
