Re: [libvirt] [PATCH] bhyve: add vga configuration for video driver

Add support for vgaconf driver configuration. In domain xml it looks like
this:

 <video>
   <driver vgaconf='io|on|off'>
   <model .../>
 </video>

It was added with bhyve gop video in mind to allow users control how the
video device is exposed to the guest, specifically, how VGA I/O is
handled.

One can refer to the bhyve manual page to get more detailed description
of the possible VGA configuration options:

https://www.freebsd.org/cgi/man.cgi?query=bhyve&manpath=FreeBSD+12-current

The relevant part could be found using the 'vgaconf' keyword.

Also, add some tests for this new feature.

Changes from v1:

* Rebased on top of current master. Specifically, the most important bit
  was merging with f5384fb4 which has added video/driver element
* In conjunction with f5384fb4 use video/driver element instead of
  video/model/driver
* Squash in conf and bhyve patches to make it easier to understand how
  it's used
* Rename *Vgaconf* to *VGAConf*
* Add a little more tests
