When creating host CPU definition usable with a given emulator, the CPU
should not be defined using an unsupported CPU model. The new @models
and @nmodels parameters can be used to limit CPU models which can be
used in the result.

The parameter can be used to request either VIR_CPU_TYPE_HOST (which has
been assumed so far) or VIR_CPU_TYPE_GUEST definition.

cpuNodeData has always been followed by cpuDecode as no hypervisor
driver is really interested in raw CPUID data for a host CPU. Let's
create a new CPU driver API which returns virCPUDefPtr directly.

Yeah, that's right. A mount point doesn't have to be a directory.
It can be a file too. However, the code that tries to preserve
mount points under /dev for new namespace for qemu does not count
with that option.

bhyve supports 'gop' video device that allows clients to connect
to VMs using VNC clients. This commit adds support for that to
the bhyve driver:
- Introducr 'gop' video device type
- Add capabilities probing for the 'fbuf' device that's
responsible for graphics
- Update command builder routines to let users configure
domain's VNC via gop graphics.

Allow to boot using UEFI rather than using an external boot loader
such as bhyveload or grub-bhyve.
Also, make LPC PCI-ISA bridge handling more flexible as now it's
needed not only for serial ports, but for bootrom as well.

Implement the BHACE_CAP_LPC_BOOTROM capability by checking the stderr
output of 'bhyve -l bootrom'. If the bootrom option is unsupported, this
will contain the following output:
bhyve: invalid lpc device configuration 'bootrom'
On newer bhyve versions that do support specifying a bootrom image, the
standard help will be printed.
Add bhyve support to virt-host-validate(1). It checks for the
essential kernel modules to be available so that user can actually
start VMs, have networking and console access.
It uses the kldnext(2)/kldstat(2) routines to retrieve modules list.
As bhyve is only available on FreeBSD and these routines were available
long before bhyve appeared, not adding any specific configure checks
for that.
Also, update tools/Makefile.am to add
virt-host-validate-$driver.[hc] to the build only if the
appropriate driver is enabled.
Add a new test to fchosttest in order to test creation of our vHBA
via the Storage Pool logic. Unlike the real code, we cannot yet use
the virVHBA* API's because they (currently) traverse the file system
in order to get the parent vport capable scsi_host. Besides there's
no "real" NPIV device here - so we have to take some liberties, at
least for now.
Instead, we'll follow the node device tests partially in order to
create and destroy the vHBA with the test node devices.

If a qemu process has died, we get EOF on its monitor. At this
point, since qemu process was the only one running in the
namespace kernel has already cleaned the namespace up. Any
attempt of ours to enter it has to fail.
This really happened in the bug linked above. We've tried to
attach a disk to qemu and while we were in the monitor talking to
qemu it just died. Therefore our code tried to do some roll back
(e.g. deny the device in cgroups again, restore labels, etc.).
However, during the roll back (esp. when restoring labels) we
still thought that domain has a namespace. So we used secdriver's
transactions. This failed as there is no namespace to enter.

This is a very historic artefact. Back in the old days of
830ba76c3e when we had macros to add arguments onto qemu command
line (!) we thought it was a good idea to let qemu write out the
PID file. So we passed -pidfile $stateDir/$domName onto the
command line. Thus, in order for tests to work we needed stable
stateDir in the qemu driver. Unfortunately, after 16efa11aa6
where stateDir is mkdtemp()-d, this approach lead to a leak of
temp dir.

If the delivery of the DEVICE_DELETED event for the vCPU being deleted
would time out, the code would not call 'qemuDomainResetDeviceRemoval'.
Since the waiting thread did not unregister itself prior to stopping the
waiting the monitor code would try to wake it up instead of dispatching
it to the event worker. As a result the unplug process would not be
completed and the definition would not be updated.

This reverts commit c96bd78e4e.
So our code is one big mess and we modify domain definition while
building qemu_command line and our hotplug code share only part
of the parsing and command line building code. Let's revert
that change because to fix it properly would require refactor and
move a lot of things.

Even though scsi storage driver builds fine on non-Linux, it
will not work properly because it relies on Linux procfs, so
disable that in configure if we're not building for Linux.
We should skip <listen type='socket'/> only if the 'socket' path
is specified because if there is no 'socket' path we need to
keep that element in migratable XML.

When libvirtd is started we call qemuDomainRecheckInternalPaths
to detect whether a domain has VNC socket path generated by libvirt
based on option from qemu.conf. However if we are parsing status XML
for running domain the existing socket path can be generated also if
the config XML uses the new <listen type='socket'/> element without
specifying any socket.
The current code doesn't make difference how the socket was generated
and always marks it as "fromConfig". We need to store the
"autoGenerated" value in the status XML in order to preserve that
information.
The difference between "fromConfig" and "autoGenerated" is important
for migration, because if the socket is based on "fromConfig" we don't
print it into the migratable XML and we assume that user has properly
configured qemu.conf on both hosts. However if the socket is based
on "autoGenerated" it means that a new feature was used and therefore
we need to leave the socket in migratable XML to make sure that if
this feature is not supported on destination the migration will fail.

Some of our tests (e.g. qemuhotplugtest) call
virDomainSaveConfig(). Now the problem is, qemuTestDriverInit()
creates a fake qemu driver and fills it with some fake
configuration. At least so we hoped. The truth is, it calls
regular virQEMUDriverConfigNew() and then fix couple of paths.
Literally. Therefore our tests see regular stateDir and configDir
for the user that is running the tests. Directories, where live
domain XMLs are stored. Let's just hope our test suite hasn't
mangled any of them.

When we are restoring a domain from a saved image, or just
updating its XML in the saved image - we have to make sure that
the ABI guests sees will not change. We have a function for that
which reports errors. But for some reason if this function fails,
we call it again with slightly different argument. Therefore it
might happen that we overwrite the original error and leave user
with less helpful one.
