This works just like pipe2(2), except it also supports fixed file descriptors. Used in a similar fashion as for other fd instantiating opcodes (like accept, socket, open, etc), where sqe->file_slot is set appropriately if two direct descriptors are desired rather than a set of normal file descriptors. sqe->addr must be set to a pointer to an array of 2 integers, which is where the fixed/normal file descriptors are copied to. sqe->pipe_flags contains flags, same as what is allowed for pipe2(2). Future expansion of per-op private flags can go in sqe->ioprio, like we do for other opcodes that take both a "syscall" flag set and an io_uring opcode specific flag set.
