8806c0db63 cpu: Unify CPUID data structures
So far, CPUID data were stored in two different data structures. First
of them was a structure allowing direct access for CPUID data according
to function number and the second was a plain array of struct
cpuX86cpuid. This was a silly design which resulted in converting data
from one type to the other and back again or implementing similar
functionality for both data structures.

The patch leaves only the direct access structure. This makes the code
both smaller and more maintainable since operations on different objects
can use common low-level operations.

All 57 tests for cpu subsystem still pass after this rewrite.

5faf88fe98 qemu: Introduce two new job types
Currently, all of domain "save/dump/managed save/migration"
use the same function "qemudDomainWaitForMigrationComplete"
to wait the job finished, but the error messages are all
about "migration", e.g. when a domain saving job is canceled
by user, "migration was cancled by client" will be throwed as
an error message, which will be confused for user.

As a solution, intoduce two new job types(QEMU_JOB_SAVE,
QEMU_JOB_DUMP), and set "priv->jobActive" to "QEMU_JOB_SAVE"
before saving, to "QEMU_JOB_DUMP" before dumping, so that we
could get the real job type in
"qemudDomainWaitForMigrationComplete", and give more clear
message further.

And as It's not important to figure out what's the exact job
is in the DEBUG and WARN log, also we don't need translated
string in logs, simply repace "migration" with "job" in some
statements.

044f2011aa Convert dhcpStartDhcpDaemon from virRun to virCommand
This is pretty straightforward - even though dnsmasq gets daemonized
and uses a pid file, those things are both handled by the dnsmasq
binary itself. And libvirt doesn't need any of the output of the
dnsmasq command either, so we just setup the args and call
virRun(). Mainly it was just a (mostly) mechanical job of replacing
the APPEND_ARG() macro (and some other *printfs()) with
virCommandAddArg*().

2a151699f1 esx: Improve error reporting for failed tasks
Instead of just reporting that a task failed get the
localized message from the TaskInfo error and include
it in the reported error message.

Implement minimal deserialization support for the
MethodFault type in order to obtain the actual fault
type.

For example, this changes the reported error message
when trying to create a volume with zero size from

  Could not create volume

to

  Could not create volume: InvalidArgument - A specified parameter was not correct.

Not perfect yet, but better than before.

The xml watchdog dump option is converted to qemu watchdog pause arg

arg since there already is a xml watchdog pause option, so a test for
the dump option to convert it from arg to xml is not added.

-Don't leak host names or ports
-Set the source protocol in qemuParseCommandline

c778fe9678 qemu: Distinguish between domain shutdown and crash
When we get an EOF event on monitor connection, it may be a result of
either crash or graceful shutdown. QEMU which supports async events
(i.e., we are talking to it using JSON monitor) emits SHUTDOWN event on
graceful shutdown. In case we don't get this event by the time monitor
connection is closed, we assume the associated domain crashed.

aefaeb3d48 qemu: call drive_del in DetachPciDiskDevice
Currently libvirt doesn't confirm whether the guest has responded to the
disk removal request.  In some cases this can leave the guest with
continued access to the device while the mgmt layer believes that it has
been removed.  With a recent qemu monitor command[1] we can
deterministically revoke a guests access to the disk (on the QEMU side)
to ensure no futher access is permitted.

This patch adds support for the drive_del() command and introduces it
in the disk removal paths.  If the guest is running in a QEMU without this
command we currently explicitly check for unknown command/CommandNotFound
and log the issue.

If QEMU supports the command we issue the drive_del command after we attempt
to remove the device.  The guest may respond and remove the block device
before we get to attempt to call drive_del.  In that case, we explicitly check
for 'Device not found' from the monitor indicating that the target drive
was auto-deleted upon guest responds to the device removal notification.

0cdc982995 qemu: call drive_unplug in DetachPciDiskDevice
Currently libvirt doesn't confirm whether the guest has responded to the

continued access to the device while the mgmt layer believes that it has
been removed.  With a recent qemu monitor command[1] we can
deterministically revoke a guests access to the disk (on the QEMU side)
to ensure no futher access is permitted.

This patch adds support for the drive_unplug() command and introduces it
in the disk removal paths.  There is some discussion to be had about how
to handle the case where the guest is running in a QEMU without this
command (and the fact that we currently don't have a way of detecting
what monitor commands are available).

Changes since v2:
 - use VIR_ERROR to report when unplug command not found
Changes since v1:
 - return > 0 when command isn't present, < 0 on command failure
 - detect when drive_unplug command isn't present and log error
   instead of failing entire command
