The initial pass at the generic ABI assumed that wait4() could be easily expressed using waitid(). Although it's true that wait4() can be built on waitid(), it's awkward enough that it makes more sense to continue to include wait4 in the generic syscall ABI. Since there is already a deprecated wait4 in the ABI, this change converts that wait4 into old_wait, and puts wait4 in the next available slot for new supported syscalls, after the platform-specific syscalls at number 260.
