We've had several bugs in the past that were
quite tricky to debug,
but would have been much easier if we'd known that a netlink operation
had failed. So, it would be desirable to actually detect and report
failures of netlink operations. While working on that, I discovered
that there are a number of other issues ranging from very small to
medium sized with the way we use netlink. This series addresses many
of them.

This series was tested as based on the pending patches adding C11
support, though I believe it trivially rebases onto current main.
Changes since v1:
* Assorted minor fixes based on Stefano's review
* Rebased on C11 branch
