This feature has been requested a few times in the liburing repository
and Discord channels, such as in [1,2].  If anything, it also helps
solve a long standing issue in the bind-listen test that results in
occasional test failures.

The patchset is divided in three parts: Patch 1 merges the getpeername
and getsockname implementation in the network layer, making further
patches easier; Patch 2 splits out a helper used by io_uring, like done
for other network commands; Finally, patch 3 plumbs the new command in
io_uring.

The syscall path was tested by booting a Linux distro, which does all
sorts of getsockname/getpeername syscalls.  The io_uring side was tested
with a couple of new liburing subtests available at:

   https://github.com/krisman/liburing.git -b socket

Based on top of Jens' for-next.
