In order to hopefully address [libvirt#147] at long last, I've picked
up Roman's patches from 2018 and attempted to forward-port them.
More specifically, I've used the [roolebo/hvf-domain] branch as a
starting point, since it seems to contain a few improvements over
[v2] and was just easier to pick up.
The code is mostly his own, so I've retained the existing authorship
information, but I've dropped Reviewed-by tags for commits that have
been modified in non-trivial ways. I've applied very minimal style
tweaks along the way, but overall I've tried to modify the existing
patches as little as possible.
I've added a few changes of my own, which I've marked as "fixup!"
when I felt that they should be squashed into the previous patch
rather than existing as separate commits.
The new test cases, such as they are, pass, and no regressions to KVM
support appear to have been introduced in the process. I don't
currently have access to a machine running macOS, so I can't verify
that it's actually possible to start a hardware-accelerated VM.
Changes from [v3]:
* reintroduced the patch that was missing in the initial version
of the forward-port;
* converted the documentation to reStructuredText and trimmed it
significantly;
* reworked virQEMUCapsAccelStr() based on Dan's suggestions;
* reworked macOS support in the test suite based on Dan's
suggestions;
* fixed a few minor issues found while doing the above.
Changes from [v2]:
* rebased on top of master;
* added a couple of simple test cases.
