...with minimal other changes: signed/unsigned warning fixes, and API adjustments. I chose std::vector instead of QVector because it does not require the contained type to have a default constructor (QVector does). All three QMeta*Private types in question didn't have a default ctor before they were ported to be held in QVectors (instead of QLists). std::vector generally also produces less executable code, and its push_back() is overloaded for rvalue references, and the code happens to pass only QMeta*Private temporaries to it, which are conveniently implicitly move-enabled. Even though std::vector doesn't care, keep the QMeta*Private classes marked as Q_MOVABLE_TYPE, so the next person doesn't wonder whether it was forgotten or intentional. There are a lot of for loops which use int-based indexing. They all needed to be adjusted to use size_t-based indexing. Eventually, we will change that to C++11 range-for loops. In most places, index validation could now be done in a single unsigned comparison, but keep that for a separate commit to keep the change minimal. Added lots of casts to int from size_t to avoid MSVC's narrowing conversion warnings. Saves more than 4.5K of text size on GCC 4.9 optimized C++11 AMD64 Linux builds.
