CLEANUP: cache: use read_u32/write_u32 to access the cache entry's hash Enabling strict aliasing fails on the cache's hash which is a series of 20 bytes cast as u32. And in practice it could even fail on some archs if the http_txn didn't guarantee the hash was properly aligned. Let's use read_u32() to read the value and write_u32() to set it, this makes sure the compiler emits the correct code to access these and knows about the intentional aliasing.
