Although theoretically both should be the same value, the niothreadids
should be used in favor of iothreads when performing comparisons. This
leaves the iothreads as a purely numeric value to be saved in the config
file. The one exception to the rule is virDomainIOThreadIDDefArrayInit
where the iothreadids are being generated from the iothreads count since
iothreadids were added after initial iothreads support.
The condition checking whether --format was specified was incorrect.
virsh crashed if the following format was used:
virsh dump VM dump --format '' --memory-only

Event implementations need to be registered before a connection to the
Hypervisor is opened, otherwise event handling can be impaired (e.g.
delayed messages). This fact is referenced in an e-mail [1], but should
also be noted in the documentation of the registration functions.

Create a separate local API that will fill in the iothreadid array
entries that were not defined by <iothread id='#'> entries in the XML.

There were some inconsistencies, eg. the number of digits used for
the day. The month name was also spelled out instead of abbreviated
in some instances.
There were some inconsistencies; now the section title is always
one of Bug Fixes, Cleanups, Documentation, Features, Improvements,
Portability, Security.
Some of the paragraphs were not properly indented: while this was
not a problem in the HTML version, you could tell the difference
in the plain text version.
The changes for releases earlier than 0.7.1 were mostly lumped
together as opposed to being tidly organized with one change per
line, like we have done from that point onwards.
As a result, they look awful in the HTML version and don't work
too well in the plain text version either.
Luckily, except for the very first releases, the information is
still very detailed, so it's enough to organize it properly.

The description for this release, unlike all other descriptions,
was inside a <p> element; however, the XSLT stylesheet contains a
template that drops all <p> elements from the output file, so it
never made it to the generated NEWS file.
Use a <li> element, same as all other releases, instead.
It should redirect stdout to /dev/null first,
then redirect stderr to whatever stdout currently points at.

After a successful creation of a directory, if some other call results
in returning a failure, let's remove the directory we created to
prevent another round trip or confusion in the caller. In particular, this
function can be called during a storage backend buildVol, so in order
to ensure that caller doesn't need to distinguish between failed create
or some other failure after create, just remove the directory we created.

Track when the logical volume was successfully created in order to
properly handle the call to virStorageBackendLogicalDeleteVol. It's
possible that the failure to create was because someone created an
LV in the pool outside of libvirt's knowledge. In this case, we don't
want to delete that LV. A subsequent or future refresh of the pool
will find the volume and cause an earlier failure

Commit id '1b5685da' refactored the code to move buildvoldef inside
the buildVol conditional; however, the VIR_FREE of the memory was
left only when 'buildret' failed, thus we're leaking memory.

As of commit id '155ca616' a 'refreshVol' is called after a buildVol
succeeds in storageVolCreateXML, thus a volStorageBackendSheepdogRefreshVolInfo
call in virStorageBackendSheepdogBuildVol is no longer necessary.
Additionally, the 'conn' parameter becomes unused.

This looks for existance of DMAR (Intel) and IVRS (AMD)
files under /sys/firmware/acpi/tables/, as a sign that
the platform has IOMMU present & enabled in the BIOS.
If these are present and /sys/kernel/iommu_groups does
not contain any entries this is taken as a sign that
the kernel has not enabled the IOMMU currently.
If no ACPI tables are found we can't distinguish between
disabled in BIOS and not present in the hardware, so we
have to give the user a generic hint.

Our apibuild.py script does not cope with ATTRIBUTE_NONNULL:
Parse Error: parsing function type, ')' expected
Got token ('name', 'char')
Last token: ('name', 'char')
Token queue: [('op', '*'), ('name', 'dconnuri'), ('sep', ')')]
Line 3297 end:
Makefile:2441: recipe for target '../../docs/apibuild.py.stamp' failed
Let's drop it. Moreover, up until e17ae3ccc2 where it was
introduced we did not really care about NULL-ity of dconnuri. And
moreover the ATTRIBUTE_NONNULL merely checks for static calls
over NULL, it won't catch the dynamic ones, where a NULL is
passed by a variable at runtime.

After creating a copy of the 'authdef' in a pool -> disk translation,
unconditionally clear the 'authType' in the resulting disk auth def
structure since that's used for a storage pool and not a disk. This
ensures virStorageAuthDefFormat will properly format the <auth> XML
for a <disk> (e.g. it won't have a <auth type='%s'.../>).
Win32 does not have support for mntent.h header, so the
method which uses this must be stubbed out.

Currently we just check that various devices are accessible.
This leads to inaccurate errors reported for /dev/kvm and
/dev/vhost-net if they exist but an unprivileged user lacks
access. Switch existing checks to look for file existance,
and add a separate check for accessibility of /dev/kvm
since some distros don't grant users access by default.

virDomainMigrateUnmanagedParams is not a good candidate for this functionality
as it is used by migrate family functions too and its have its own checks that
are superset of extracted and we don't need to check twice.
Actually name of the function is slightly misleading as there is also a check
for consistensy of flags parameter alone. So it could be refactored further and
reused by all migrate functions but for now let it be a matter of a different
patchset.
It is *not* a pure refactoring patch as it introduces offline check for older
versions. Looks like it must be done that way and no one will be broken too.

Finally on this step we get what we were aimed for - toURI{1, 2} (and
migration{*} APIs too) now can work thru V3_PARAMS protocol. Execution path
goes thru unchanged virDomainMigrateUnmanaged adapter function which is called
by all target places.
Note that we keep the fact that direct migration never works
thru V3_PARAMS proto. We can't change this aspect without
further investigation.

p2p plain and direct function are good candidates for code reuse. Their main
function is same - to branch among different versions of migration protocol and
implementation of this function is also same. Also they have other common
functionality in lesser aspects. So let's merge them.
But as they have different signatures we have to get to convention on how to
pass direct migration 'uri' in 'dconnuri' and 'miguri'. Fortunately we alreay
have such convention in parameters passed to toURI2 function, just let's follow
it. 'uri' is passed in miguri and dconnuri is ignored.

Direct migration should work if *perform3 is present but *perform
is not. This is situation when driver migration is implemented
after new version of driver function is introduced. We should not
be forced to support old version too as its parameter space is
subspace of newer one.
This is more structured code so it will be easier to add branch for _PARAMS
protocol here. It is not a pure refactoring strictly speaking as we remove
scenarios for broken cases when driver defines V3 feature and implements
perform function. So it is additionally a more solid code.

'useParams' parameter usage is an example of control coupling. Most of the work
inside the function is done differently except for the uri check. Lets split
this function into two, one with extensible parameters set and one with hardcoded
parameter set.

The internal representation of a JSON array counts the items in
size_t. However, for some reason, when asking for the count it's
reported as int. Firstly, we need the function to return a signed
type as it's returning -1 on an error. But, not every system has
integer the same size as size_t. Therefore, lets return ssize_t.
