rtmp: fix multiple broken overflow checks
Sanity checks like `data + size >= data_end || data + size < data' are broken, because `data + size < data' assumes pointer overflow, which is undefined behavior in C. Many compilers such as gcc/clang optimize such checks away. Use `size < 0 || size >= data_end - data' instead.
