Thanks, applied.

Perhaps there is some reason to prefer compiler builtins over libc
that I'm not seeing?

It's because I pulled container_of from the kernel, and the kernel
header files has to provide offsetof since we don't use the standard
header files --- and it has to work across a bunch of compilers and
architectures.
