Users may want to run the init command of a container as a special
user / group. This is achieved by adding <inituser> and <initgroup>
elements. Note that the user can either provide a name or an ID to
specify the user / group to be used.
This commit also fixes a side effect of being able to run the command
as a non-root user: the user needs rights on the tty to allow shell
job control.

Some containers may want the application to run in a special directory.
Add <initdir> element in the domain configuration to handle this case

Some qemu arch/machine types have built in platform devices that
are always implicitly available. For platform serial devices, the
current code assumes that only old style -serial config can be
used for these devices.
Apparently though since -chardev was introduced, we can use -chardev
in these cases, like this:
-chardev pty,id=foo
-serial chardev:foo
Since -chardev enables all sorts of modern features, use this method
for platform devices.

vcpu properties gathered from query-hotpluggable cpus need to be passed
back to qemu. As qemu did not use the node-id property until now and
libvirt forgot to pass it back properly (it was parsed but not passed
around) we did not honor this.
This patch adds node-id to the structures where it was missing and
passes it around as necessary.
The test data was generated with a VM with following config:
<numa>
<cell id='0' cpus='0,2,4,6' memory='512000' unit='KiB'/>
<cell id='1' cpus='1,3,5,7' memory='512000' unit='KiB'/>

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.

Starting from qemu 2.9, more granular options are supported. Add parser
for the relevant bits.
With this patch libvirt is able to parse the host and target IQN of from
the JSON pseudo-protocol specification.
This corresponds to BlockdevOptionsIscsi in qemu qapi.
'SocketAddress' structure was changed to contain 'inet' instead of
'tcp' since qemu commit c5f1ae3ae7b. Existing entries have a backward
compatibility layer.
Libvirt will parse 'inet' and 'tcp' as equivalents.
When added in multiple previous commits, it was used only with -device
qxl(-vga), but for some QEMUs (< 1.6) we need to add this
functionality when using -vga qxl as well.

On some platforms the number of bits in the cbm_mask might not be
divisible by 4 (and not even by 2), so we need to properly count the
bits. Similar file, min_cbm_bits, is properly parsed and used, but if
the number is greater than one, we lose the information about
granularity when reporting the data in capabilities. For that matter
always report granularity, but if it is not the same as the minimum,
add that information in there as well.
