Handle line number changes

Sometimes a piece of code moves through the file as new code gets added, however it keeps reproducing the same problem (be it build issue, kernel warning, etc) but today logspec is unable to understand if the line of the code change can be ignored or not, so it always creates a new issue.

No file, test, or entry point is named. Start by locating the Python logic that compares reported line changes and creates issues, then reproduce a warning or build problem after code is inserted above it. Done means repeated problems are recognized as the same issue when only their line numbers change, without suppressing genuinely different problems.
