[Libguestfs] [nbdkit PATCH 0/5] More retry fixes

[Eric Blake]

I think this is my last round of patches for issues I identified with
the retry filter.  With this in place, it should be safe to interject
another filter in between retry and the plugin.

Eric Blake (5):
  retry: Don't call into closed plugin
  tests: Refactor test-retry-reopen-fail.sh
  tests: Enhance retry test to cover failed reopen
  server: Move prepare/finalize/close recursion to backend.c
  server: Ensure .finalize and .close are called as needed
