More specifically, everything that's tested by qemucapabilities
now goes through qemucaps2xml as well.
Ideally we'll rewrite both so that listing all test cases is
unnecessary and they get picked up automatically by listing the
contents of the input directory instead, but that's a refactor
for another day :)

While qemucaps2xml has a meager two test cases to its name, we
have plenty of data from qemucapabilities which is taken from
actual QEMU binaries, covers pretty much all supported QEMU
versions and architectures and is even in the right format already!
Rewrite qemucaps2xml so that it uses qemucapabilities data as
input. Right now we have a single test case, but we're going to
add a lot more next.

Now that committing transactions using pid == -1 means that we're
not fork()-ing to run the transaction in a specific namespace, we
can utilize the transaction processing semantics in order to
start, run a or multiple commands, and then commit the
transaction without being concerned with other interactions or
transactions interrupting the processing. This will eventually
allow us to have a single place where all the paths can be
locked, followed by relabeling and unlocking again.

It will be desirable to run transactions more often than we
currently do. Even if the domain we're relabeling the paths for
does not run in a namespace. If that's the case, there is no need
to fork() as we are already running in the right namespace. To
differentiate whether transaction code should fork() or not the
@pid argument now accepts -1 (which means do not fork).

In the future, the transactions are not going to be optional and

whether an API must be fully implemented or plain #define is

Even though the current use of the functions does not require full
implementation with transactions (none of the callers passes a path
somewhere under /dev), it doesn't hurt either. Moreover, in
future patches the paradigm is going to shift so that any API
that touches a file is required to use transactions.

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.

None of the things testUpdateQEMUCaps adjusts are applicable
for tests that use the DO_TEST_CAPS macros, i.e.

The architecture must be chosen before we even open the caps
file, CPU models are already present and the expensive HostModel
computation was already done in virQEMUCapsLoadCache.
Introduce FLAG_REAL_CAPS and skip the whole testUpdateQEMUCaps

Commit 82327038 moved a couple of checks out of the XML parser
into the domain validation; however, those checks seem to be more
useful as hypervisor specific checks rather than the more general
domain conf checks (nothing in the docs indicate a specific error).
Fortunately only QEMU was processing the memoryBacking, thus
add the changes to qemuDomainDefValidateMemory and change the
code a bit to make usage of the similar deref to def->mem and
the mem->nhugepages filter.

virDomainDefCollectBootOrder() is called for every item on the list
for each type of device. One of the checks it makes is to gather the
order attributes from the <boot> element of all devices, and assure
that no two devices have been given the same order.
Since (internally to libvirt, *not* in the domain XML) an <interface
type='hostdev'> is on both the list of hostdev devices and the list of
network devices, it will be counted twice, and the code that checks
for multiple devices with the same boot order will give a false
positive.
To remedy this, we make sure to return early for hostdev devices that
have a parent.type != NONE.
