Subject: [RFC PATCH liburing v1 0/5] liburing: Add sendto(2) and recvfrom(2) support

Hello,

I submitted an RFC patchset to add sendto(2) and recvfrom(2) support
for io_uring. This RFC patchset adds the support for the liburing.

There are 5 patches in this series. 4 from me. 1 from Nugra.

For PATCH 1/5, it is just a .gitignore clean up.

## Changes Summary
 - Update io_uring.h header (sync with the kernel).

 - Add `io_uring_prep_{sendto,sendto}` functions.

 - Add test program for `IORING_OP_SENDTO` and `IORING_OP_RECVFROM`.

 - Add documentation for `io_uring_prep_{sendto,sendto}` functions.


## How to test

This patchset is based on branch "xattr-getdents64" commit:

  18d71076f6c97e1b25aa0e3b0e12a913ec4717fa ("src/include/liburing.h: style cleanups")
