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.
The list of supported CPU models in domain capabilities is stored in
virDomainCapsCPUModels. Let's use the same object for storing CPU models
in QEMU capabilities.

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.
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.
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
full names for individual parameters.

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.

Extract whether a given drive has a tray and whether there is no image
inserted.
Negative logic for the image insertion is chosen so that the flag is set
only if we are certain of the fact.
The structure actually contains migration statistics rather than just
the status as the name suggests. Renaming it as
qemuMonitorMigrationStats removes the confusion.

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:

Instead of using qemuMonitorJSONDevGetBlockExtent (which I plan to
remove later) extract the data in place.
Additionally add a flag that will be set when the wr_highest_offset was
extracted correctly so that callers can act according to that.
The test case addition should help make sure that everything works.
QEMU_CAPS_SEAMLESS_MIGRATION capability says QEMU supports
SPICE_MIGRATE_COMPLETED event. Thus we can just drop all code which
polls query-spice and replace it with waiting for the event.

Rather than have a separate routine to parse the alias of an iothread
returned from qemu in order to get the iothread_id value, parse the alias
when returning and just return the iothread_id in qemuMonitorIOThreadInfoPtr
This set of patches removes the function, changes the "char *name" to
"unsigned int" and handles all the fallout.
Use the new single function instead of calling
qemuMonitorJSONGetBlockStatsInfo and
qemuMonitorJSONGetBlockStatsParamsNumber. This will allow to delete the
functions later while still maintaining coverage.
When trying clang, it found out that we were comparing sizeof with 0
even though we wanted to check the return value of memcmp. That showed
us that the test was wrong and it needs a fix as well.

Improve the monitor function to also retrieve the guest state of
character device (if provided) so that we can refresh the state of
virtio-serial channels and perhaps react to changes in the state in
future patches.
This patch changes the returned data from qemuMonitorGetChardevInfo to
return a structure containing the pty path and the state for all the
character devices.
The change to the testsuite makes sure that the data is parsed
correctly.
To unify future additions that require information from "query-chardev"
rename qemuMonitorGetPtyPaths and friends to qemuMonitorGetChardevInfo
and move the allocation of the returned hash into the top level
function.
