checks, but nothing else to avoid extraneous allocations and any

'libxml2' deprecated the 'xmlIndentTreeOutput' thread-local variable as
well as the 'xmlThrDefIndentTreeOutput' function for setting the global
default, which we use in our code for formatting the metadata sub-XML.
'libxml2' also for now doesn't provide a way to set target indentation
level in 'xmlSaveCtxt' which would allow us to use the modern output
APIs, we can't replace our use of 'xmlDumpNode'. (See
https://gitlab.gnome.org/GNOME/libxml2/-/issues/989 )
Since the indentation is enabled by default in libxml2 and our most
commonly used code which calls xmlDumpNode lives in a standalone
process, where we don't override the setting, just removing the override
will result in identical behaviour.
For the use cases which do live in a process we don't fully control and
thus the default could have been overriden, the result would be that the
<metadata> element would be un-indented, but that is still valid XML.
Thus to fix the deprecated use just stop setting 'xmlIndentTreeOutput'.

'xmlIndentTreeOutput' is now deprecated by libxml2.
The default value set by libxml2 is '1', and the vbox driver resides
only inside the standalone daemon where the value will not be changed by
us thus there's no observable change in behaviour.

bhyve supports queue configuration for the NVMe disks:
maxq Max number of queues.
qsz Max elements in each queue.
Map that to the disk driver's "queues" and "queue_size" attributes
respectfully, so:
<driver name='file' type='raw' queues='2' queue_size='256'/>
results in:
-s N:0,nvme,/tmp/disk.img,maxq=2,qsz=256

In RHEL and Fedora, the built-in GNUTLS default priority is changed
from "NORMAL" to "@SYSTEM", but because libvirt sets an explicit
policy with gnutls we don't honour that. Instead we force "NORMAL"
unless the 'tls_priority' meson option is changed.
In RPM builds, meanwhile, we ask for "@LIBVIRT,SYSTEM" to make it
look for a libvirt specific profile first, falling back to "@SYSTEM"
This changes the meson option to default to "@LIBVIRT,SYSTEM" if the
crypto-policies config is present on the local machine and the meson
option -Dsystem=true is given.
This gives developers more appropriate default behaviour, matching
that seen in package builds.

Firstly, there's no need to list header files in
ch_driver_sources (we don't do that anywhere else, and meson is
smart enough to figure them out). And secondly, the list of
source file is not sorted which means new source files are added
in random order.
Thus, drop header files from the list and sort it.

Libvirt's philosophy is that for a running domain there are two
(in general distinct) definitions: live definition (reflects the
running state) and inactive definition (used to seed the live
definition when domain is being created). That's why we have
VIR_DOMAIN_AFFECT_LIVE and VIR_DOMAIN_AFFECT_CONFIG flags to APIs
that modify domain definitions.
Well, the CH driver doesn't do this distinction. Fix this by
making the domain definition transient when it's being created.

Domain capabilities XML is formatted (mostly) using
FORMAT_PROLOGUE and FORMAT_EPILOGUE macros. These format opening
and closing stanzas for given element. The FORMAT_PROLOGUE macro
even tries to be clever and format element onto one line (if the
element isn't supported), but that's not enough. Fortunately, we
have virXMLFormatElement() which formats elements properly, so
let's switch macros into using that.
