* Add cppcheck handler match on misra msg
* Use --file-filter cppcheck option
Cppcheck recently added --file-filter so that cppcheck only checks the
filtered files, even when using --project option, which checks all files
in the project, by default. The --ccpcheck-build-dir option didn't help
enough (at all?).
* Added C test cases
Also fixed and assumed typo: foo.c, instead of foo.cpp
* Replace hard-coded full path filenames
Attempt to fix the windows platform test execution.
* Fix typo - foo.c, instead of foo.cpp
* Reset buffer var between tests
* Handle header files in cppcheck
Cppcheck isn't designed to check header files, stand-alone. Daniel
Marjamäki suggested using --suppress options to avoid FPs.
* Fix Vint complaint in cppcheck handler.
* Fix file path in cppcheck handler
