Gabriel Krisman Bertazi ff140cc862 io_uring: Introduce IORING_OP_LISTEN
IORING_OP_LISTEN provides the semantic of listen(2) via io_uring.  While
this is an essentially synchronous system call, the main point is to
enable a network path to execute fully with io_uring registered and
descriptorless files.
