Add new approach to properly test status XML files by supplying a full
XML file rather than generating synthetic test cases by prepending the
status header. The two tests introduced here are copies of existing
cases using the synthetic header so that current level of testing is
kept. The files are chosen to excercising the vcpu and blockjob quirks
present in the current testing.

The libvirt_storage_backend_sheepdog_priv.la library depends on symbols
provided in the libvirt_driver_storage_impl.la library. As such the
latter must be listed 2nd when passed to the linker to avoid symbol
resolution problems. This mistake is being masked by the sheepdog
driver linking in a second copy of the storage driver code. Remove
this duplicate linkage of backend source and fix the test link order.

Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
Now that we have the ability to easily open connections to secondary
drivers, eg network:///system, it is possible to reimplement the
virDomainNetResolveActualType method in terms of the public API. This
avoids the need to have the network driver provide a callback for it.

conf: expand network device callbacks to cover resolving NIC type
mistakenly dropped qemuxml2argvtest from the tests due to a typo.
Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
Currently the QEMU driver will call directly into the network driver
impl to modify resolve the atual type of NICs with type=network. It
has todo this before it has allocated the actual NIC. This introduces
a callback system to allow us to decouple the QEMU driver from the
network driver.
This is a short term step, as it ought to be possible to achieve the
same end goal by simply querying XML via the public network API. The
QEMU code in question though, has no virConnectPtr conveniently
available at this time.

Since update to glibc-2.26 removed the /usr/include/rpc/rpc.h we used until now,
it showed us a problem with not using XDR_CFLAGS properly. On linux that
variable has usually -I/usr/include/tirpc because we already probe for it
properly, we just don't use it everywhere we need. It is needed by wireshark
dissector as well as testutilsqemu.c (through includes) so the build fails with:
wireshark/src/packet-libvirt.c:33:10: fatal error: rpc/xdr.h: No such file or directory

The commandhelper binary is a helper for commandtest that
validates what file handles were inherited. For this to
work reliably we must not have any libraries that leak
file descriptors into commandhelper. Unfortunately some
versions of gnutls will intentionally open file handles
at library load time via a constructor function.
We previously hacked around this in
commit 4cbc15d037

tests: don't fail with newer gnutls
gnutls-3.3.0 and newer leaves 2 FDs open in order to be backwards
compatible when it comes to chrooted binaries [1]. Linking
commandhelper with gnutls then leaves these two FDs open and
commandtest fails thanks to that. This patch does not link
commandhelper with libvirt.la, but rather only the utilities making
the test pass.
Based on suggestion from Daniel [2].
[1] http://lists.gnutls.org/pipermail/gnutls-help/2014-April/003429.html
[2] https://www.redhat.com/archives/libvir-list/2014-April/msg01119.html
That fix relied on fact that while libvirt.so linked with
gnutls, libvirt_util.la did not link to it. With the
introduction of the util/vircrypto.c file that assumption
is no longer valid. We must not link to libvirt_util.la
at all - only gnulib and libc can (hopefully) be relied
on not to open random file descriptors in constructors.

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.

This mock (which is actually not mock at all, see later) can redirect
all accesses to a path into another path. There is no need to
create mocks for particular directories, you just create a directory
with all the data a redirect the test there.
In the future, this should also be able to register callbacks for
calls/paths, e.g. when the test is going to write into anything under
"/sys/devices", call function fce(); Then in the open() call we would
add information about the fd into some structure and in write() we
would call fce() with parameters like @path to write to, @data to
be written and pointer to optional return value, so that fce() itself
could stop the call from happening or change its behaviour. But
that's an idea for a latter day.
This is not a mock because it will not be preloaded, but compiled in
the test itself. See future patches for usage.

All mocked functions are related to numactl/virNuma and rely only on

because it is so nicely self-contained NUMA mock, it is named

* Extract filling bhyve capabilities from virBhyveDomainCapsBuild()

* Also, just presence of the firmware files is not sufficient

* Add tests to domaincapstest for the main caps possible flows:
- when UEFI bootrom is supported
- when video (fbus) is supported
- neither of above is supported
One of the main reasons for introducing host-model CPU definition in a
domain capabilities XML was the inability to express disabled features
in a host capabilities XML. That is, when a host CPU is, e.g., Haswell
without x2apic support, host capabilities XML will have to report it as
Westmere + a bunch of additional features., but we really want to use
Haswell - x2apic when creating a host-model CPU.
Unfortunately, I somehow forgot to do the last step and the code would
just copy the CPU definition found in the host capabilities XML. This
changed recently for new QEMU versions which allow us to query host CPU,
but any slightly older QEMU will not benefit from any change I did. This
patch makes sure the right CPU model is filled in the domain
capabilities even with old QEMU.

If driver modules are enabled turn storage driver backends into
dynamically loadable objects. This will allow greater modularity for
binary distributions, where heavyweight dependencies as rbd and gluster
can be avoided by selecting only a subset of drivers if the rest is not
necessary.
The storage modules are installed into 'LIBDIR/libvirt/storage-backend/'
and users can override the location by using
'LIBVIRT_STORAGE_BACKEND_DIR' environment variable.
rpm based distros will at this point install all the backends when
libvirt-daemon-driver-storage package is installed.

So far the NSS module looks up only hostnames as provided by

not enough: e.g. when there's a fresh new guest being installed
(with some generic hostname) say from a live ISO image; or some
(older) systems don't advertise their hostname in DHCP
transactions at all.
In cases like that it would be helpful if we translate domain
name as seen by libvirt too so that users can:
# virsh start $dom && ssh $dom

while older libvirt module maintains its current behaviour (that
is translating guest provided names into IP addresses).
