Cppcheck integration

[marktwtn]

The detected and fixed errors list:

• Assign a value that is never used
• Reassign a value before the old one has been used
• The scope of the variable can be reduced
• The behaviour of using void pointers in calculations is undefined
• Uninitialized variable
• Shadow variables

The file cppcheck_suppress suppresses the errors which should not be treated as errors. The reason is written in the file.

The sanitizer.mk is renamed as dynamic-analysis.mk. And there is another file static-analysis.mk for static code analysis.
