Use C++ header files instead of C header files. (#21192) * use cstring instead of string.h * use cstdio instead of stdio.h * remove inttypes.h * use cstdlib instead of stdlib.h * use cstdint instead of stdint.h * #include <cstddef> * cstdlib * use cmath * remove stddef.h * use cassert * use csignal * use ctime * use cerror * rebase master 2021-06-09 04:46:22 +08:00			`#include <cstdint>`
