Improve shm_mq portability around MAXIMUM_ALIGNOF and sizeof(Size). Revise the original decision to expose a uint64-based interface and use Size everywhere possible. Avoid assuming that MAXIMUM_ALIGNOF is 8, or making any assumption about the relationship between that value and sizeof(Size). If MAXIMUM_ALIGNOF is bigger, we'll now insert padding after the length word; if it's smaller, we are now prepared to read and write the length word in chunks.
