071fe09260 vz: handle sourceless cdroms
SDK handles empty cdroms all right. We just need to
pass "" instead of NULL (not setting is good too).

However we can get problems here. Disk detaching treats source
as ids. Fortunately disk detaching is not supported for cdroms
yet and for hard disks we can not get empty source - this is prohibitited
by xml parsing code.

caff6b8043 vz: fix vzCheckUnsupportedDisks format checks for cdroms
Current version of the function does not check format of cdroms at all.
At the same time prlsdkGetDiskInfo give hints that cdroms always
have format VIR_STORAGE_FILE_RAW. So fix vzCheckUnsupportedDisks.

About structure of checks. As we don't have means to store format
in SDK we always have only one format in every situation. So instead
of setting boolean let's get allowed format instead and finally compare
it to the requested. This structure of checks seems stable to me
because we have only one format in every situation.

38e1e06845 vz: remove check for auto file format for disks
VIR_STORAGE_FILE_AUTO can not be set from xml description.
At the same time we don't set disks format to this value
as for example qemu does. Thus this we can never get this
value in format.

b33c14b342 graphics: make address attribute for listen type='address' optional
We support omitting listen attribute of graphics element so we should
also support omitting address attribute of listen element.  This patch
also updates libvirt to always add a listen element into domain XML
except for VNC graphics if socket attribute is specified.

38c9973f36 domain_conf: parse listen attribute while parsing listen elements
Move the compatibility code out of virDomainGraphicsListensParseXML()
into virDomainGraphicsListenDefParseXML().  This also fixes a small
inconsistency between the code and error message itself.

Before this patch we would search first listen element that is
type='address' to validate listen and address attributes. After this
patch we always take the first listen element regardless of the type.

This shouldn't break anything since all drivers supports only one
listen.

72475ac3b3 conf: Allow all volume modes for disk type='lun' sources
Commit 82ba41108a made possible to use direct mapped iSCSI
volumes in qemu as disk sources but didn't remove the define time check.

Rework the check by simplifying the condition and allow any volumes to
be used with disk type='lun'.

1222a3032b libxl: Free migration cookie
Commit id 'f9edcfa4' added cookie manipulation for libxl; however, some
cookie crumb cleanup was missed. Found by Coverity.

In libxlDomainMigrationBegin, the cookie is allocated and baked; however,
the mig ingredients weren't cleaned up.

In libxlDomainMigrationPrepare, when the 'mig' cookie is added to the
args, set the 'mig = NULL'; otherwise, other failure paths between when
the code ate the cookie data and when it was added to args would fail
to clean up the crumbs.

52760707bc qemu: More qemu_monitor_json cleanups
Recent adjustments to the code produced a litany of coverity false
positives, but only because the "standard" procedure of setting a
variable to NULL after it was assigned to something else and keeping
the *Free/*FREE call in the cleanup path wasn't kept. So this patch
makes those adjustments (assign variable to NULL and remove the if
'ret < 0' condition to clean it up).

e54b81604d admin: Fix passing an incorrect readonly attribute to virNetServerServiceNew
When registering admin UNIX socket, a new service is created for it. This
service is incorrectly initialized to be readonly, which is later inherited by
all clients connected to the socket. In libvirt-admin's case there currently
isn't any use for the attribute anyway, but since the socket has root-only
access permissions, the least we can do is to make every admin client
connected to it report readonly as false.

abd2272c02 secret: Alter virSecretGetSecretString
Rather than returning a "char *" indicating perhaps some sized set of
characters that is NUL terminated, alter the function to return 0 or -1
for success/failure and add two parameters to handle returning the
buffer and it's size.

The function no longer encodes the returned secret, rather it returns
the unencoded secret forcing callers to make the necessary adjustments.

Alter the callers to handle the adjusted model.
