Since this is something between PV and HVM, it makes sense to put the
setting in place where domain type is specified.
To enable it, use <os><type machine="xenpvh">xenpvh</type></os>. It is
also included in capabilities.xml, for every supported HVM guest type - it
doesn't seems to be any other requirement (besides new enough Xen).

With the assumption that all Xen >= 4.6 contains a pkgconfig file for
libxenlight, commit 5bdcef13 dropped the fallback check to probe
libxenlight with LIBVIRT_CHECK_LIB. At the time it was not known that
the various Xen pkgconfig files are in the -runtime package in Fedora,
instead of the traditional -devel package. This bug [1] was fixed in
Fedora > 28, but until Fedora 28 reaches EOL we'll need to re-introduce
the fallback check.

The libxl_domain_config_from_json API appeared in Xen 4.5, hence
there is no need to check for its existence after changing the

Currently the libxl driver claims support for Xen >= 4.4, but
Xen 4.4 and 4.5 are no longer supported upstream. Let's increase
the minimum supported Xen version to 4.6 and change the defined
LIBXL_API_VERSION to 0x040500, which is the API version defined
when Xen 4.6 was released.
Since Xen 4.6 contains a pkgconfig file, drop the now unused code
that falls back to using LIBVIRT_CHECK_LIB in the absence of
pkgconfig file. In addition, bumping the LIBXL_API_VERSION
required adjusting the calls to libxl_set_vcpuaffinity to account
for the extra parameter in the 0x040500 version of the API.

As a general rule any time we switch() on something that is an enum, we
want to have a case for every enum constant. The -Wswitch warning will
report any switch where we've violated this rule, except if that switch
has a default case.
Unfortunately it is reasonable to want to list all enum constants *and*
also have a default case. To get a warning in that scenario requires
that we turn on -Wswitch-enum.
In a few cases where we explicitly don't want to list all enum cases, we
can discard the enum type checking by casting the value to a plain int.

The -Wextra flag bundle gained a new warning -Wcast-function-type.
This complains if you cast between two function prototypes where
the number of parameters or their data types are not compatible.
Unfortunately we need such "bad" function casts for our event
callbacks. It is possible to silence the warning by first casting
to the generic "void (*)(void)" function prototype, but that is
rather ugly to add throughout libvirt code.

Undefined symbols are a bad thing in general because they can get
resolved in unexpected ways at runtime if multiple sources provide the
same symbol name. For example both glibc and libtirpc may provide XDR
symbols and we want to ensure that we resolve to libtirpc if that's what
we originally built against.
The toolchain maintainers thus strongly recommend that all applications
use the '-z defs' linker flag to prevent undefined symbols. This is
shortly becoming part of the default linker flags for RPMs. As an added
benefit this aligns Linux builds with Windows builds, where the linker
has never permitted undefined symbols.

The libxl library allows a libxl_domain_config object to be serialized
from/to a JSON string. Use this to allow testing of the XML to
libxl_domain_config conversion process. Test XML is converted to
libxl_domain_config, which is then serialized to json. A json template
corresponding to the test XML is converted to a libxl_domain_config
object using libxl_domain_config_from_json(), and then serialized
back to json using libxl_domain_config_to_json(). The two json
docs are then compared.
Using libxl to convert the json template to a libxl_domain_config
object and then back to json provides a simple way to account for
any changes or additions to the json representation across Xen
releases.
