liburing-2.4 release

- Add io_uring_{major,minor,check}_version() functions.
- Add IO_URING_{MAJOR,MINOR,CHECK}_VERSION() macros.
- FFI support (for non-C/C++ languages integration).
- Add io_uring_prep_msg_ring_cqe_flags() function.
- Deprecate --nolibc configure option.
- CONFIG_NOLIBC is always enabled on x86-64, x86, and aarch64.
- Add support for IORING_REGISTER_USE_REGISTERED_RING and use if available.
- Add io_uring_close_ring_fd() function.
- Add io_uring_prep_msg_ring_fd_alloc function.
- Add io_uring_free_buf_ring() and io_uring_setup_buf_ring() functions.
- Ensure that io_uring_prep_accept_direct(), io_uring_prep_openat_direct(),
  io_uring_prep_openat2_direct(), io_uring_prep_msg_ring_fd(), and
  io_uring_prep_socket_direct() factor in being called with
  IORING_FILE_INDEX_ALLOC for allocating a direct descriptor.
- Add io_uring_prep_sendto() function.

liburing-2.3 release

- Support non-libc build for aarch64.
- Add io_uring_{enter,enter2,register,setup} syscall functions.
- Add sync cancel interface, io_uring_register_sync_cancel().
- Fix return value of io_uring_submit_and_wait_timeout() to match the
  man page.
- Improvements to the regression tests
- Add support and test case for passthrough IO
- Add recv and recvmsg multishot helpers and support
- Add documentation and support for IORING_SETUP_DEFER_TASKRUN
- Fix potential missing kernel entry with IORING_SETUP_IOPOLL
- Add support and documentation for zero-copy network transmit
- Various optimizations
- Many cleanups
- Many man page additions and updates

liburing-2.2 release

- Support non-libc builds.
- Optimized syscall handling for x86-64/x86/aarch64.
- Enable non-lib function calls for fast path functions.
- Add support for multishot accept.
- io_uring_register_files() will set RLIMIT_NOFILE if necessary.
- Add support for registered ring fds, io_uring_register_ring_fd(),
  reducing the overhead of an io_uring_enter() system call.
- Add support for the message ring opcode.
- Add support for newer request cancelation features.
- Add support for IORING_SETUP_COOP_TASKRUN, which can help reduce the
  overhead of io_uring in general. Most applications should set this flag,
  see the io_uring_setup.2 man page for details.
- Add support for registering a sparse buffer and file set.
- Add support for a new buffer provide scheme, see
  io_uring_register_buf_ring.3 for details.
- Add io_uring_submit_and_wait_timeout() for submitting IO and waiting
  for completions with a timeout.
- Add io_uring_prep_{read,write}v2 prep helpers.
- Add io_uring_prep_close_direct() helper.
- Add support for SQE128 and CQE32, which are doubly sized SQE and CQE
  rings. This is needed for some cases of the new IORING_OP_URING_CMD,
  notably for NVMe passthrough.
- ~5500 lines of man page additions, including adding ~90 new man pages.
- Synced with the 5.19 kernel release, supporting all the features of
  5.19 and earlier.
- 24 new regression test cases, and ~7000 lines of new tests in general.
- General optimizations and fixes.
