The user and system includes (files included with "" vs with <>) are not consistent.
- Update the condign standard and add a clean definition on when "system" includes shall be used. The C99 standard is quite relaxed, but static analyzers treat system includes different. The suggestion is to include any header not owned by TS (or not following TS coding standard) to be included as a system include.
- Fix the C/C++ files in the repo.
