Currently we can perform `send` and `recv` via io_uring. And now, we
are going to add `sendto` and `recvfrom` support for io_uring.
Note that:
Calling `send(fd, buf, len, flags)` is equivalent to calling
`sendto(fd, buf, len, flags, NULL, 0)`. Therefore, `sendto`
is a superset of `send`.
Calling `recv(fd, buf, len, flags)` is equivalent to calling
`recvfrom(fd, buf, len, flags, NULL, NULL)`. Therefore, `recvfrom`
is a superset of `recv`.
As such, let's direct the current supported `IORING_OP_{SEND,RECV}` to
`io_{sendto,recvfrom}`. These functions will also be used for
`IORING_OP_{SENDTO,RECVFROM}` operation in the next patches.
