copyin()/copyout() for message type is separated from msgsnd()/msgrcv() and it is done from its wrapper functions to support 32-bit emulations. After I implemented this, I have briefly referenced NetBSD and Darwin. NetBSD passes copyin()/copyout() function pointers from wrappers. Darwin passes size of message type as an argument, which is actually similar to my first implementation (P4 109706). We may revisit these implementations later.
