Commit 5ed235c6 added unnecessary redifinition of
virDomainCapsDeviceHostdev in conf/domain_capabilities.h. This breaks
build with clang 3.4:

In file included from conf/domain_capabilities.c:25:
conf/domain_capabilities.h:88:44: error: redefinition of typedef
'virDomainCapsDeviceHostdev' is a C11 feature
[-Werror,-Wtypedef-redefinition]
typedef struct _virDomainCapsDeviceHostdev virDomainCapsDeviceHostdev;
                                           ^
conf/domain_capabilities.h:86:44: note: previous definition is here
typedef struct _virDomainCapsDeviceHostdev virDomainCapsDeviceHostdev;

So drop one of those.

If the call to virXPathNodeSet to set naddresses fails, Coverity notes
that the subsequent VIR_ALLOC_N cannot have a negative value (well it
probably wouldn't be negative per se).

Coverity noted that in adminServerListClients if virNetServerGetClients
returns a -1 into ret, then the call virObjectListFreeCount in cleanup
will not be very happy.

Adjust the code to skip the cleanup label and just return -1 if
virNetServerGetClients fails.

Both instances use VIR_WARN() to print the error from a failed

virGetLastErrorMessage.

This matches how we handle spice gl='no' even if spice GL isn't
supported. Not too interesting in practice but I figure we should
be consistent

Commit 0b36b0e9 broke polkit agent startup when attempting to fix a
coverity warning. Refactor it properly so that we don't need the 'cmd'
intermediate variable.

qemuDomainCheckDiskPresence has short-circuit code to skip the
determination of the disk backing chain for storage formats that can't
have backing volumes. The code treats VIR_STORAGE_FILE_NONE as not
having backing chain and skips the call to qemuDomainDetermineDiskChain.

This is wrong as qemuDomainDetermineDiskChain is responsible for storage
format detection and has logic to determine the default type if format
detection is disabled.

This allows to storage passed via <disk type="volume"> to circumvent the
enforcement to have correct storage format or that we shall default to
format='raw', since we don't set the default type via the post parse
callback for "volume" backed disks as the translation code could come up
with a better guess.

This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1328003

Extract the relevant parts of the existing checker and reuse them for
blockcopy since copying to a non-block device creates an invalid
configuration.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1209802

In qemuCheckDiskConfig would now use virDomainDiskSourceIsBlockType just
as a glorified version of virStorageSourceIsBlockLocal that reports
error messages. Replace it with the latter including the message for
clarity.

Commit c820fbff added support for iSCSI
disk as backing for <disk device='lun'>. We would not use it for a disk
type="volume" with direct access mode which basically maps to direct
iSCSI usage. Fix it by adding the storage source type accessor that
resolves the volume type.

Commit 36025c55 tried to improve error reporting for <disk type="lun">
but reused the code in LXC which doesn't care about the actual disk
type. The error messages would then contain a bogous hint that the
config for the 'lun' device is invalid which might not be the case.

Re-do the relevant portion of the commit with the original message.

For disks sources described by a libvirt volume we don't need to do a
complicated check since virStorageTranslateDiskSourcePool already
correctly determines the actual disk type.

Replace the checks using a new accessor that does not open-code the
whole logic.

In 7884d089 I've started to refactor qemu_monitor_json.c.
Thing is, it's current structure is nothing like the rest of our
code. The @ret variable is rewritten all the time, if()-s are
nested instead of using goto and so on.

Use vshCommandOptScaledInt instead of vshCommandOptULongLong so that
values with suffixes can be passed when bytes are being passed along.
Values for the iops parameters still need to be given in the absolute
form as they are not bytes but numbers.

Fron c3bd0019 on instead of creating the following path for
cgroups:

  /sys/fs/cgroupX/$name.libvirt-$driver

we generate rather more verbose one:

  /sys/fs/cgroupX/$driver-$id-$name.libvirt-$driver

where $name is optional and included iff contains allowed chars.
See original commit for more reasoning. Now, problem with the
original commit is that we are unable to start any LXC domain
after it. Because when starting LXC container, the CGroup layout
is created by our lxc_controller process and then detected and
validated by libvirtd. The validation is done by trying to match
detected layout against all the possible patterns for cgroup
paths that we've ever had. And the commit in question forgot to
update this part of the code.
