So far, we only report an error if formatting the siblings bitmap
in NUMA topology fails.
Be consistent and always report error in virCapabilitiesFormatXML.
The new VIR_CONNECT_COMPARE_CPU_FAIL_INCOMPATIBLE flag for
virConnectCompareCPU can be used to get an error
(VIR_ERR_CPU_INCOMPATIBLE) describing the incompatibility instead of the
usual VIR_CPU_COMPARE_INCOMPATIBLE return code.

When CPU comparison APIs return VIR_CPU_COMPARE_INCOMPATIBLE, the caller
has no clue why the CPU is considered incompatible with host CPU. And in
some cases, it would be nice to be able to get such info in a client
rather than having to look in logs.
To achieve this, the APIs can be told to return VIR_ERR_CPU_INCOMPATIBLE
error for incompatible CPUs and the reason will be described in the
associated error message.

For future work we want to get info for not only the free memory
but overall memory size too. That's why the function must have
new signature too.

Automatically allocate PCI addresses for devices instead
of hardcoding them in the driver code. The current
allocation schema is to dedicate an entire slot for each devices.
Also, allow having arbitrary number of devices.
In a number of places in the bhyve driver, virObjectUnlock()
is called with an arg without check if the arg is non-NULL, which
could result in passing NULL value and a warning like:
virObjectUnlock:340 : Object 0x0 ((unknown)) is not a virObjectLockable instance
* src/bhyve/bhyve_driver.c (bhyveDomainGetInfo)
(bhyveDomainGetState, bhyveDomainGetAutostart)
(bhyveDomainSetAutostart, bhyveDomainIsActive)
(bhyveDomainIsPersistent, bhyveDomainGetXMLDesc)
(bhyveDomainUndefine, bhyveDomainLookupByUUID)
(bhyveDomainLookupByName, bhyveDomainLookupByID)
(bhyveDomainCreateWithFlags, bhyveDomainOpenConsole):
Check if arg is not NULL before calling virObjectUnlock on it.
Add a helper function virBhyveGetDomainTotalCpuStats() to
obtain process CPU time using kvm (kernel memory interface)
and use it to set cpuTime field of the virDomainInfo struct in
bhyveDomainGetInfo().
- do not lose new definition for an active domain
- do not leak oldDef
- do not set dom->id if virDomainSaveConfig() fails
- do not call virObjectUnlock(vm) if vm is NULL
Implement bhyveDomainCreateXML function.

Fix incorrect ATTRIBUTE_NONNULL usage introduced in 17b17565
which caused build failure:
bhyve/bhyve_driver.c:127:48: error: expected ')'
bhyveDriverGetCapabilities(bhyveConnPtr driver ATTRIBUTE_NONNULL)
^
bhyve/bhyve_driver.c:127:27: note: to match this '('
bhyveDriverGetCapabilities(bhyveConnPtr driver ATTRIBUTE_NONNULL)
Pushed under the build breaker rule.
At the beginning of the function we gain a reference to the driver
capabilities. Then, we call format function (*) which if failed, unref
over caps is called. Then, at the end another unref occurs.
* - Moreover, the format was not called over gained caps, but over
privconn->caps directly which is not allowed anymore.

The driver passed as the only argument to the function should never be
NULL so there's no need to check it. After removing it, the whole
function collapses to a single line doing ref over driver
capabilities.

nmdm is a FreeBSD driver which allows to create a pair of tty
devices one of which is passed to the guest and second is used
by the client.
This patch adds new 'nmdm' character device type. Its definition
looks this way:
<serial type='nmdm'>
<source master='/dev/nmdm0A' slave='/dev/nmdm0B'/>
</serial>
Master is passed to the hypervisior and slave is used for client
connection.
Also implement domainOpenConsole() for bhyve driver based on that.
New functionalities:
- connectGetMaxVcpus - on bhyve hardcode this value to 16
- nodeGetFreeMemory - do not use physmem_get on FreeBSD, since
it might get wrong value on systems with
more than 100GB of RAM
- nodeGetCPUMap - wrapper only for mapping function, currently not
supported by FreeBSD
- nodeSet/GetMemoryParameters - wrapper only for future improvements,
currently not supported by FreeBSD
Any source file which calls the logging APIs now needs
to have a VIR_LOG_INIT("source.name") declaration at
the start of the file. This provides a static variable
of the virLogSource type.

Coverity found an issue in lxc_driver and uml_driver that we don't
check the return value of register functions.
I've also updated all other places and unify the way we check the
return value.

At this point it has a limited functionality and is highly
experimental. Supported domain operations are:
* define
* start
* destroy
* dumpxml
* dominfo
It's only possible to have only one disk device and only one
network, which should be of type bridge.
