While we discourage people to use the old style of specifying
UEFI for their domains (the old style is putting path to the FW
image under /domain/os/loader/ whilst the new one is using
/domain/os/@firmware), some applications might have not adapted
yet. They still rely on libvirt autofilling NVRAM path and
figuring out NVRAM template when using the old way (notably
virt-install does this). We must preserve backcompat for this
previously supported config approach. However, since we really
want distro maintainers to leave --with-loader-nvram configure
option and rely on JSON descriptors, we need to implement
autofilling of NVRAM template for the old way too.

Introduced in v5.10.0-449-gcf44ec55 it used
virshCommaStringListComplete() to generate list of options. But
this is not correct because the '--source' argument of the
'domifaddr' doesn't accept a string list (for instance
"arp,agent,lease") rather than a single string. Therefore, the
completer must return these strings separately and thus must
refrain from using virshCommaStringListComplete().

At the same time, now that we have strings we need declared as
an enum we can use TypeToString() instead of copying strings.

When building RPMs for libvirt the PO files are part of libvirt-libs
package.  Now that we generate libvirt.pot during build time the POT
creation date is also generated at that time.

The issue here is that when building libvirt-libs for x86_64 and i686
the generated libvirt.pot file will have different POT creation date
which affects installed PO files as well which leads to conflict when
installing both x86_64 and i686 packages.

GLib header files annotate every API with a version number.

It is possible to define some constants before including
glib.h which will result in useful compile time warnings.

Setting GLIB_VERSION_MIN_REQUIRED will result in a warning
if libvirt uses an API that was deprecated in the declared
version, or before. Such API usage should be rewritten to
use the documented new replacement API.

Setting GLIB_VERSION_MAX_ALLOWED will result in a warning
if libvirt uses an API that was not introduced until a
version of GLib that's newer than our minimum declared
version. This avoids accidentally using functionality
that is not available on some supported platforms.

The g_date_time_new_from_iso8601() function was introduced as
a replacement for strptime in

  commit 810613a6
  Author: Daniel P. Berrangé <berrange@redhat.com>
  Date:   Mon Dec 23 15:37:26 2019 +0000

    src: replace strptime()/timegm()/mktime() with GDateTime APIs set

Unfortunately g_date_time_new_from_iso8601 isn't available until
glib 2.56, and backporting it requires alot of code copying and
poking at private glib structs.

This reverts domain_conf.c back to its original parsing logic prior
to 810613a6, but using g_date_time_new()
instead of gmtime(). The other files are then adapted to follow a
similar approach.

When allowing/denying a device in devices CGroupV2 we have to

static and all it does it looks up a device in a hash table (also
known as map in BPF terminology). A map is referenced via an FD
which can be acquired via virBPFCreateMap() and like any other FD
it should be closed when no longer needed. However, we close it
twice: the first time in virCgroupV2DevicesAttachProg() which
closes it unconditionally, and the second time in either
virCgroupV2DevicesCreateProg() or
virCgroupV2DevicesPrepareProg(). Remove the second close.

Unfortunately there doesn't seem to be a straightforward way to get

two tools behave slightly differently in that regard, it's more

to keep it inline in the Makefile with all the annoying escaping
