use "sentinel" function attribute for variadic lists
This attribute can help gcc notice when callers forget to add a NULL sentinel to the end of the function. This is our first use of the sentinel attribute, but we shouldn't need to #ifdef for other compilers, as __attribute__ is already a no-op on non-gcc-compatible compilers.
