Add sparse checker support to the build system (Gerd Hoffman)
This adds support for running the sparse checker during the build process. Left it off by default for now, build becomes very noisy with sparse checking turned on as it has to complain alot (partly even in the system headers!). The qemu code base needs quite some cleanups before we should consider turning it on by default.
