We sometimes need to compare whole structures in an assert. It is possible to use the existing macros on each field, but when the whole structure has to be checked, it is more convenient to simply compare the whole structure memory
Add a dedicated assert macro, ASSERT_MEMEQ, to allow bare memory comparision

nit: should we rewrite this as a real function?
void hexdump(const char *prefix, void *buf, size_t len) { .. }
