Add CodeQL Workflow for Code Security Analysis This pull request introduces a CodeQL workflow to enhance the security analysis of our repository. CodeQL is a powerful static analysis tool that helps identify and mitigate security vulnerabilities in our codebase. By integrating this workflow into our GitHub Actions, we can proactively identify and address potential issues before they become security threats. We added a new CodeQL workflow file (.github/workflows/codeql.yml) that - Runs on every push and pull request to the main branch. - Excludes queries with a high false positive rate or low-severity findings. - Does not display results for third-party code, focusing only on our own codebase. Testing: To validate the functionality of this workflow, we have run several test scans on the codebase and reviewed the results. The workflow successfully compiles the project, identifies issues, and provides actionable insights while reducing noise by excluding certain queries and third-party code. Deployment: Once this pull request is merged, the CodeQL workflow will be active and automatically run on every push and pull request to the main branch. To view the results of these code scans, please follow these steps: 1. Under the repository name, click on the Security tab. 2. In the left sidebar, click Code scanning alerts. Additional Information: - You can further customize the workflow to adapt to your specific needs by modifying the workflow file. - For more information on CodeQL and how to interpret its results, refer to the GitHub documentation and the CodeQL documentation.

Summary
This pull request introduces a CodeQL workflow to enhance the security analysis of this repository.
What is CodeQL
CodeQL is a static analysis tool that helps identify and mitigate security vulnerabilities. It is primarily intra-function but does provide some support for inter-function analysis. By integrating CodeQL into a GitHub Actions workflow, it can proactively identify and address potential issues before they become security threats.
For more information on CodeQL and how to interpret its results, refer to the GitHub documentation and the CodeQL documentation (https://codeql.github.com/ and https://codeql.github.com/docs/).
What this PR does
We added a new CodeQL workflow file (.github/workflows/codeql.yml) that
Validation
To validate the functionality of this workflow, we have run several test scans on the codebase and reviewed the results. The workflow successfully compiles the project, identifies issues, and provides actionable insights while reducing noise by excluding certain queries and third-party code.
Using the workflow results
If this pull request is merged, the CodeQL workflow will be automatically run on every push to the main branch and on every pull request to the main branch. To view the results of these code scans, follow these steps:
Is this a good idea?
We are researchers at Purdue University in the USA. We are studying the potential benefits and costs of using CodeQL on open-source repositories of embedded software.
We wrote up a report of our findings so far. The TL;DR is "CodeQL outperforms the other freely-available static analysis tools, with fairly low false positive rates and lots of real defects". You can read about the report here: https://arxiv.org/abs/2310.00205
Review of engineering hazards

False positives: We find that around 20% of errors are false positives, but that these FPs are polarized and only a few rules contribute to most FPs. We find that the top rules contributing to FPs are: cpp/uninitialized-local, cpp/missing-check-scanf, cpp/suspicious-pointer-scaling, cpp/unbounded-write, cpp/constant-comparison, and cpp/inconsistent-null-check. Adding a filter to filter out certain rules that contribute to a high FP rate can be done simply in the workflow file.
