[libvirt] [PATCH 00/24] hostdev: Cleanups and fixes

[Andrea Bolognani]

Part of an ongoing quest to fix:

  libvirt management of VFIO devices can lead to host crashes
  https://bugzilla.redhat.com/show_bug.cgi?id=1272300

Previous episode:

  [PATCH v2 0/9] PCI hostdev refactoring
  https://www.redhat.com/archives/libvir-list/2016-January/msg01066.html

The plan:

  Once this is in, rebase the series mentioned above on top of it;
  hopefully it will be smaller and easier to review. Once *that*
  is in, rebase / rewrite the actual bug fix - probably the latter,
  because the code has changed a lot since I posted it

In this episode:

  01-06  Cleanups in the test cases; mostly unrelated, but commit
         24 depends on them

  07-17  More cleanups and (I believe) farily uncontroversial
         changes, aimed at making the actual changes either
         smaller or more obvious

  18-19  Change in variable names that make the intended semantics
         clearer, which should in turn make the follow-up changes
         easier to review

  Up until here there should be basically no change in behavior

     20  Bug fix

     21  Improvement to error reporting

     22  The whole point of this series, and also the commit
         where it's more likely that I might have gotten something
         wrong :) I haven't been able to figure out a way to split
         it into smaller chunks, sorry

     23 Another bug fix

     24 Test the changes made by the rest of the series

Cheers.
