libeth: add cacheline / struct layout assertion helpers Add helpers to assert struct field layout, a bit more crazy and networking-specific than in <linux/cache.h>. They assume you have 3 CL-aligned groups (read-mostly, read-write, cold) in a struct you want to assert, and nothing besides them. For 64-bit with 64-byte cachelines, the assertions are as strict as possible, as the size can then be easily predicted. For the rest, make sure they don't cross the specified bound.
