... instead of GetIterator(). This allows us to avoid loading the cache entirely in SetTo(), and allows consumers to read the cache much more efficiently than loading it all into memory and then freeing it again afterwards. This technically breaks API/ABI, however the Package Kit APIs are not considered stable (I don't think.) All consumers adjusted. As we build the host tools with modern GCC only, I made update_package_requires use a C++11 lambda function. All others use out-of-line static methods. "time pkgman list-repos -v" (which has to read the whole cache) is ~0.5s before this change, and ~0.25s after this change, on my test VM.
