Commit 3f71c797 added 'qemu_id' field to track the id of the cpu
as reported by query-cpus. The patch did not include changes necessary
to propagate the id through the functions matching the data to the
libvirt cpu structures and thus all vcpus had id 0.

The field is named 'enable_id' in other structures and a patch recently
added 'qemu_id' which has different semantics. To avoid confusion in the
tests rename the field.

Storing of the ID will allow simpler extraction of data present only in
query-cpus without the need to call qemuMonitorGetCPUInfo in statistics
paths.

The new name is virCPUDataFormat.

Add support for a duration/length for the bps/iops and friends.

Modify the API in order to add the "blkdeviotune." specific definitions
for the iotune throttling duration/length options

    total_bytes_sec_max_length
    write_bytes_sec_max_length
    read_bytes_sec_max_length
    total_iops_sec_max_length

Extended the qemuMonitorCPUInfo with a halted flag. Extract the halted

If not initialized and the virAsprintf to jsonreply or fulllablel fails,
then the call to qemuMonitorTestFree will take stack data.

Since introduction of chardev hotplug the code was wrong for the UDP
case and basically created a TCP socket instead. Use proper objects and
type for UDP.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1377602

Until now the test was rather useless since it didn't check the
arguments formatted and didn't use properly configured chardev objects.

Add the expected arguments and instrument the test to validate them.
Modify some test cases to actually add valid data.

Note that the UDP test data is currently wrong due to a bug.

The chardev attach test would do all the tests in one virTestRun
instance. If one sub-test failed then the test would report failure
improperly and the error would be hard to debug since the error pointer
was overwritten.

Return whether a vcpu entry is hotpluggable or online so that upper
layers don't have to infer the information from other data.

Advantage is that this code can be tested by unit tests.

The reported data is unusual so add it to the test suite.

Test the algorithm that extracts the order in which the vcpu entries
were plugged in on a sample of data created by plugging in vcpus
arbitrarily.

Power 8 platform's basic hotpluggable unit is a core rather than a
thread for x86_64 family. This introduces most of the complexity of the
matching code and thus needs to be tested.

The test data contain data captured from in-order cpu hotplug and
unplug operations.

During review it was reported that adding at least 11 vcpus creates a
collision of prefixes in the monitor matching algorithm. Add a test case
to verify that the problem won't happen.

As the combination algorithm is rather complex and ugly it's necessary
to make sure it works properly. Add test suite infrastructure for
testing it along with a basic test based on x86_64 platform.

To allow matching up the data returned by query-cpus to entries in the
query-hotpluggable-cpus reply for CPU hotplug it's necessary to extract
the QOM path as it's the only link between the two.

Prepare to extract more data by returning an array of structs rather than
just an array of thread ids. Additionally report fatal errors separately
from qemu not being able to produce data.

The first argument should be const char ** instead of
char **, because this is a search function and as such it
doesn't, and shouldn't, alter the haystack in any way.

This change means we no longer have to cast arrays of
immutable strings to arrays of mutable strings; we still
have to do the opposite, though, but that's reasonable.

Use a name that contains the command used to get the information.

Rather than pass the disks[i]->info.alias to qemuMonitorSetDrivePassphrase
and then generate the "drive-%s" alias from that, let's use qemuAliasFromDisk
prior to the call to generate the drive alias and then pass that along
thus removing the need to generate the alias from the monitor code.

qemuMonitorMigrationParams is a better name for a structure which
contains various migration parameters. While doing that, we should use

We have the code for attaching redirdevs for ages now.
Unfortunately, our monitor code that handles talking to the qemu
process was missing a little piece of code that actually enabled
the feature.

BTW: it really is called "type" on the monitor, even though it's
called "name" on the cmd line. Don't ask.

The caller is already aware that the params are missing and the

Negative logic for the image insertion is chosen so that the flag is set

Earlier virtType was of type int. After, introducing the enum VIR_DOMAIN_VIRT_NONE,
the type of virtType is modified to virDomainVirtType.

We use the function to create a virDomainXMLOption object that is
required for some functions. However, we don't pass the driver
pointer to the object anywhere - rather than pass NULL. This
causes trouble later when parsing a domain XML and calling post
parse callbacks:

Remove one instance of the field being present so that the code that
sets that flag can be tested.

Now that qemuMonitorGetAllBlockStatsInfo collects also wr_highest_offset
the whole function can be killed.
