tests. This ensures that we get information from all files, not just files that had functions that were run. This brings down the total number of covered functions significantly: | Line Coverage | Functions | --------+--------------------+------------------+ Before: | 43.0% (3308/7699) | 48.8% (266/545) | After: | 15.2% (3308/21821) | 15.1% (266/1762) | Excluded generated Qt and D-Bus files from the tests. Also exlcuded pngcheck, since it's mostly third-party code. TODO: Create some truncated ROM images to use as test cases and run them in rpcli, and also compare extracted images.
