Cxx Sqale Model Project intial import. PClint Rules and some CppCheck Rules

Hi @wenns, @Bertk,

As you know we have several xml files that we maintain one for each sensor and after this there is a default-profile that has severities. This on top of the new cxx model just brings maintenance overhead. So my proposal is to maintain a single file cxx-model-project.xml and consider the others as auto generated files for now, or even later, create a parser to read the rules straight from the project.

So this pull request is meant to provide the project file with the most updated rules definitions available in the repository (with latest changes from Bert).  Additionally, this project contains already many characteristics of the pclint and some of cppcheck.

Changes to rules will then be done in the project only. 

what do you think about this?

Thanks
JC
