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.

Certain XML features that aren't in the <cpu> block map to -cpu
flags on the qemu cli. If one of these is specified but the user
didn't explicitly pass an XML <cpu> model, we need to format a
default model on the command line.
The current code handles this by sprinkling this default cpu handling
among all the different flag string formatting. Instead, switch it
to do this just once.
This alters some test output slightly: the previous code would
write the default -cpu in some cases when no flags were actually
added, so the output was redundant.

It turns out that our implementation of the hashing function is
endian-dependent and thus if used on various architectures the testsuite
may have different results. Work this around by mocking virHashCodeGen
to something which does not use bit operations instead of just setting a
deterministic seed.
Disk serial schema has extra '.+' allowed characters in comparison
with check in code. Looks like there is no reason for that as qemu
allows any character AFAIK for serial. This discrepancy is originated
in commit id '85d15b51' where the ability to add serial was added.
Alter the disk-serial test to add a disk with all the possible
characters listed as the serial value.
Prior to qemu 2.5 the node names would not be generated, thus would be
missing from 'query-blockstats' and 'query-named-block-nodes'. Test that
the code correctly detects nothing.
Additionally make sure that a VM without disks does not cause problems.
The test case change is necessary as our test file checker does not play
well with empty files.
Treat an NULL string equivalent to an empty string in
virTestCompareToFile so that callers don't need to add additional logic
in case when a test produces no output.
'virt-aa-helper' is compiled when both WITH_LIBVIRTD and
WITH_SECDRIVER_APPARMOR are defined. The test was run only when
WITH_SECDRIVER_APPARMOR was defined thus causing a build failure when
building without the daemon.
Driver modules proved to be reliable for a long time. Since support for
not building modules complicates the code and makefiles drop it.

qemu 2.9 returns an extra layer in the backing data if a block job is
active. Add a test case to see whether our code properly detects and
ignores such layer.
The test data was prepared by creating a backing chain of qcow2 images
(with qemu-img and with libvirt's snapshot feature).
One of the layers was then merged back by doing a block-commit:
virsh blockcommit VM hda --top /var/lib/libvirt/images/b
and then a block-copy job was started and kept in synchronized phase:
virsh blockcopy VM hda /tmp/tgt.img --transient job

Remove the complex and unreliable code which inferred the node name
hierarchy only from data returned by 'query-named-block-nodes'. It turns
out that query-blockstats contain the full hierarchy of nodes as
perceived by qemu so the inference code is not necessary.
In query blockstats, the 'parent' object corresponds to the storage
behind a storage volume and 'backing' corresponds to the lower level of
backing chain. Since all have node names this data can be really easily
used to detect node names.
In addition to the code refactoring the one remaining test case needed
to be fixed along.

This is now handled by virFileCacheNewData().
virQEMUCapsCacheValidate() is removed because this is now handled by

an explicit target path name; however, in the absence of that, we need
uniqueness in the names we generate internally.
Before the changes we'd get /var/lib/libvirt/qemu/channel/target/unknown.sock
for each instance of
<channel type='unix'>
