215b5daf43 m4: libxl: properly fail when libxl is required
We specify "true" as the fail-action for LIBVIRT_CHECK_PKG.

This was used when we had a fallback to non-pkg-config detection,
then removed in commit 5bdcef13d1
later re-introduced in commit dc3d2c9f8c
and then left in when removing the old detection again in
commit 18981877d2

Remove it to properly error out when libxl was requested but not
detected.

aca7ff5f70 libxl: add support for PVH
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).

dc3d2c9f8c libxl: fallback to lib probe if pkgconfig file not found
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.

212df3f957 libxl: remove configure check for libxl_domain_config_from_json
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
minimum supported Xen version to 4.6. Remove the check and its
use in the tests.

5bdcef13d1 libxl: drop support for Xen < 4.6
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.

ed45361044 libxl: add explicit linkage to xenstore library
Since

    libxl: implement virDomainBlockStats

    Introduce initial support for domainBlockStats API

the libxl driver calls a couple of xenstore APIs, so it must explicitly
link to this library rather than rely on indirect linkage via libxl or
other xen libraries.

d8e8b63d30 libxl: Add a test suite for libxl_domain_config generator
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.

e64f2fab92 m4/virt-arg: Rename LIBVIRT_ARG_WITH* macros
LIBVIRT_ARG_WITH_ALT is more generic than LIBVIRT_ARG_WITH, which
is tailored at switching features on and off.

Rename the macros according to their intended purpose, and add
some documentation to help developers pick between the two.
