c94720f86a qemuMonitorTextGetAllBlockStatsInfo: Fix line validation
There's a bug in the function. We expect the following format for
the data we are parsing here:

  key: value

So we use strchr() to find ':' and then see if it is followed by
space. But the check that does just that is slightly incorrect.

9f7d9891f0 qemu: monitor: Remove JSON impls of drive_add and drive_del
qemu won't ever add those functions directly to QMP. They will be
replaced with 'blockdev-add' and 'blockdev-del' eventually. At this time
there's no need to keep the stubs around.

Additionally the drive_del stub in JSON contained dead code in the
attempt to report errors. (VIR_ERR_OPERATION_UNSUPPORTED was never
reported). Since the text impl does have the same message it is reported
anyways.

0f4d317204 qemu-hotplug: fix eject media
QEMU changed the error message to:

        "Tray of device 'drive-sata0-0-1' is not open"

and they may change the error massage in the future.

This updates the code to not depend on the text from the error message
but only on error itself.

4ac14cde9a qemu: snapshot: Correctly report qemu error on 'savevm'
Since 'savevm' was not converted to QMP libvirt has to parse for error
strings in the text monitor output. One of the unhandled errors is
produced when qemu treats a device as unmigratable.

As current qemu actually does support AHCI migration this bug is
applicable only to older versions of qemu.

69a3b0df2d Drive hot-unplug: reliable parsing of HMP results
Hot-unplugging a disk from a guest that supports hot-unplugging generates an error
in the libvirt log when running QEMU with the "-msg timestamp=on" flag.

2015-08-06 10:48:59.945+0000: 11662: error : qemuMonitorTextDriveDel:2594 :
operation failed: deleting drive-virtio-disk4 drive failed:
2015-08-06T10:48:59.945058Z Device 'drive-virtio-disk4' not found

This error is caused because the HMP results are getting prefixed with a timestamp.
Parsing the output is not reliable with STRPREFIX as the results can be prefixed with a timestamp.

Using strstr ensures that parsing the output works whether the results are prefixed or not.

bdc05128d7 qemu: monitor: Count block stats fields in qemuMonitorGetAllBlockStatsInfo
Our virDomainBlockStatsFlags API uses the old approach where, when it's
called without the typed parameter array, returns the count of parameters
supported by qemu.

The supported parameter count is obtained via separate monitor calls
which is a waste since we can calculate it when gathering the data.

This patch adds code to the qemuMonitorGetAllBlockStatsInfo workers that
allows to track the count of supported fields reported by qemu and will
allow to remove the old duplicate code.

f6563bc361 qemu: monitor: Implement HMP version for listing all block device stats
Add a different version of parser for "info blockstats" that basically
parses the same information as the existing copy of the function.

This will allow us to remove the single device version
qemuMonitorGetBlockStatsInfo in the future.

The new implementation uses few new helpers so it should be more
understandable and provides a test case to verify that it works.

    virBufferFreeAndReset(&buf);
    virReportOOMError();

with:
if (virBufferCheckError(&buf) < 0)

This should not be a functional change (unless some callers
misused the virBuffer APIs - a different error would be reported
then)

1e947cf7d8 qemu: specify domain in host-side PCI addresses when needed/supported
This uses the new QEMU_CAPS_HOST_PCI_MULTIDOMAIN capability when
present, for -devivce pci-assign, -device vfio-pci, and -pcidevice.

While creating tests for this new functionality, I noticed that the
xmls for two existing tests had erroneously specified an
until-now-ignored domain="0x0002", so I corrected those two tests, and
also added two failure tests to be sure that we alert users who
attempt to use a non-zero domain with a qemu that doesn't support it.

The dtrace probe macros rely on the logging API. We can't make

that'd be a circular include. Instead simply split the dtrace

reason for them to be in the main internal.h header.

cc78d7ba0e Remove contiguous CPU indexes assumption
When getting CPUs' information, it assumes that CPU indexes
are not contiguous. But for ppc64 platform, CPU indexes are not
contiguous because SMT is needed to be disabled, so CPU information
is not right on ppc64 and vpuinfo, vcpupin can't work corretly.

This patch is to remove the assumption to be compatible with ppc64.

Test:
   4 vcpus are assigned to one VM and execute vcpuinfo command.

   Without patch: There is only one vcpu informaion can be listed.
   With patch: All vcpus' information can be listed correctly.
