[PATCH v3 0/7] crypto: misc fixes and improvements to cert handling

["Daniel P. Berrangé" <berrange@redhat.com>]

This series includes three patches that were posted a fairly
long time ago. They are borderline between a feature request
and a bug fix, but I'm classing them more bug fix, since they
addressing issues with cert acceptance that we really should
not have had.

The patches by Henry had outstanding comments from myself,
and I've chosen to simply fix them in two followup commits
of my own now to get this over the line.

The patch from "matoro" was not accepted because they were
contributed under a github alias. With our change to have
a more relaxed interpretation of the DCO allowing any
"known identity", we can now accept this patch. It had
some conflicts with Henry's patch which I've fixed up.

Then there is one other small bug fix and one improvement
to use a newer gnutls API.

Changed in v3:

 - Re-ordered patch for fixing error reporting to be
   near start of series, instead of end
 - Add unit test for validating error reporting with
   incomplete CA chains
 - Unit test to validate that an Error is filled on
   expected failures

Changed in v2:

 - Update to latest upstream
