Remove all boost:: namespace prefix for uint32_t, int32_t etc. (fixed-width types) - Also removes all references to boost/cstdint.hpp and replaces it with stdint.h (The 'correct' replacement would be <cstdint>, but not all of our compilers support that). 2016-10-31 21:30:52 +00:00			`#include <stdint.h>`
