From: Markus Armbruster g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches

gen_marshal_output() uses its parameter name only for name of the generated function. Name it after the type being marshaled instead of its caller, and drop duplicates. Saves 7 copies of qmp_marshal_output_int() in qemu-ga, and one copy of qmp_marshal_output_str() in qemu-system-*.
