With iothreadid's allowing any 'id' value for an iothread_id, the
iothreadsched code needs a slight adjustment to allow for "any"
unsigned int value in order to create the bitmap of ids that will
have scheduler adjustments. Adjusted the doc description as well.

Remove the iothreadspin array from cputune and replace with a cpumask
to be stored in the iothreadids list.

Adjust the test output because our printing goes in order of the iothreadids
list now.

Since it's only ever referenced in domain_conf.c, make the function
static, but also will need to move it to somewhere before it's referenced
rather than forward referencing it.

Add 'thread_id' to the virDomainIOThreadIDDef as a means to store the
'thread_id' as returned from the live qemu monitor data.

Remove the iothreadpids list from _qemuDomainObjPrivate and replace with
the new iothreadids 'thread_id' element.

Rather than use the default numbering scheme of 1..number of iothreads
defined for the domain, use the iothreadid's list for the iothread_id

Since iothreadids list keeps track of the iothread_id's, these are
now used in place of the many places where a for loop would "know"
that the ID was "+ 1" from the array element.

The new tests ensure usage of the <iothreadid> values for an exact number
of iothreads and the usage of a smaller number of <iothreadid> values than
iothreads that exist (and usage of the default numbering scheme).

Adding a new XML element 'iothreadids' in order to allow defining
specific IOThread ID's rather than relying on the algorithm to assign
IOThread ID's starting at 1 and incrementing to iothreads count.

This will allow future patches to be able to add new IOThreads by
a specific iothread_id and of course delete any exisiting IOThread.

Each iothreadids element will have 'n' <iothread> children elements
which will have attribute "id".  The "id" will allow for definition
of any "valid" (eg > 0) iothread_id value.

On input, if any <iothreadids> <iothread>'s are provided, they will
be marked so that we only print out what we read in.

On input, if no <iothreadids> are provided, the PostParse code will
self generate a list of ID's starting at 1 and going to the number
of iothreads defined for the domain (just like the current algorithm
numbering scheme).  A future patch will rework the existing algorithm
to make use of the iothreadids list.

On output, only print out the <iothreadids> if they were read in.

All the libraries use same parameters when building, why not have it in
one place at the begining of the Makefile.

This will also ensure no new mock library will have a problem with
missing e.g. MINGW_EXTRA_LDFLAGS.

If a user hot-attaches the guest agent channel libvirt would ignore it
until the restart of libvirtd or shutdown/destroy and start of the VM
itself.

This patch adds code that opens or closes the guest agent connection
according to the state of the guest agent channel according to
connect/disconnect events.

To allow opening the channel from the event handler qemuConnectAgent
needed to be exported.

When the guest agent channel gets hotplugged to a VM, libvirt would
still report that "QEMU guest agent is not configured" rather than
stating that the connection was not established yet.

Currently the code won't be able to connect to the agent after hotplug
but that will change in a later patch.

As the qemuFindAgentConfig() helper is quite helpful in this case move
it to a more usable place and export it.

The API didn't use virDomainObjEndAPI to release the domain object thus
it leaked a reference to it.

Since the code is now separated into the common helper, we can reuse it
instead of maintaining two copies.

Both attach and detach functions get called only if the type matches.

Pushed previous patch (commit id 'd45dadae') too quickly...

The patch just updates the patch from Laine's suggestions.

Commit ca329299 caused build errors in bhyvexml2argvtest.c because of
some undefined variables.

Pushing under the build breaker rule.

Fix for such a case:
1. Domain A and B xml contain the same SRIOV net hostdev(<interface
type='hostdev' /> with same pci address).
2. virsh start A (Successfully, and configure the SRIOV net with
custom mac)
3. virsh start B (Fail because of the hostdev used by domain A or other
reason.)
In step 3, 'virHostdevNetConfigRestore' is called for the hostdev
which is still used by domain A. It makes the mac/vlan of the SRIOV net
change.

Code Change in this fix:
1. As the pci used by other domain have been removed from
'pcidevs' in previous loop, we only restore the nic config for
the hostdev still in 'pcidevs'(used by this domain)
2. update the comments to make it more clear

Similar to what was done for the channel socket in the previous commit.

Rather than depend on the RPM to put it in place, since this doesn't
cover the qemu:///session case. Currently auto allocated socket path is
completely busted with qemu:///session

https://bugzilla.redhat.com/show_bug.cgi?id=1105274

And because we chown the directory at driver startup now, this also fixes
autosocket startup failures when using user/group=root

https://bugzilla.redhat.com/show_bug.cgi?id=1044561
https://bugzilla.redhat.com/show_bug.cgi?id=1146886

Not sure if this is required, but it makes things consistent with the
rest of the directories.

Rather than duplicate libDir for each new path

- Make sure aarch64 host-passthrough works correctly
- Make sure libvirt doesn't choke on cpu model=host, which is what
  virt-install/virt-manager were incorrectly specifying up until recently.

virDomainGetJobStats is able to report statistics of a completed
migration, however to get usable downtime and total time statistics both
hosts have to keep synchronized time. To provide at least some
estimation of the times even when NTP daemons are not running on both
hosts we can just ignore the time needed to transfer a migration cookie
to the destination host. The result will be also inaccurate but a bit
more predictable. The total/down time will just be at least what we
report.
