Add a debian container with cppcheck installation routine inside, capable of performing cppcheck analysis on Xen-only build including cross-builds for arm32 and x86_64. Populate build jobs making use of that container to run cppcheck analysis to produce a text report (xen-cppcheck.txt) containing the list of all the findings. This patch does not aim at performing any sort of bisection. Cppcheck is imperfect and for now, our goal is to at least be aware of its reports, so that we can compare them with the ones produced by better tools and to be able to see how these reports change as a result of further infrastructure improvements (e.g. exception list, rules exclusion).
