compiler.h: add offsetof() and container_of()
offsetof() is a C99 construct; provided here as an ersatz for older
systems.
container_of() is a nonstandard but highly useful construct, which
allows data structure control items like tree structures to be
embedded in larger data structures without the penalty of extra
pointers and allocations.
