Commit id '887dd362' added support for a netfs pool format type 'cifs'
and 'gluster' in order to add rng support for Samba and glusterfs netfs
pools. Originally, the CIFS type support was added as part of commit
id '61fb6979'. Eventually commit id 'b325be12' fixed the gluster rng
definition to match expectations.

As it turns out the CIFS rng needed a similar change since the directory
path is not an absDirPath, rather just a dirPath will be required.

We're using Polkit's DBus API so no need to check wether this feature is
supported. We don't use the result or the path to the pkcheck program
anywhere.

We were using "complicated" error printing in virnetservertest even
though we could've just dispatched the error.  Also add some good
practices that might come in handy (the code may fail without proper
initialization and event loop).

If virNetServerMDNSAddEntry() fails when adding a service to a server,
it doesn't decrease the number of services.  Hence access to their

Instead of initializing return value to zero (success) and overwriting
it on every failure just before the control jumps onto 'out' label,
let's initialize to an error value and set to zero only when we are
sure about the success. Just follow the pattern we have in the rest of
the code.

Seems the property has been deprecated for qemu, although seemingly ignored.

This patch enforces from a libvirt perspective that a scsi-block 'lun'
device should not provide the 'serial' property.

https://bugzilla.redhat.com/show_bug.cgi?id=1200206

Commit id '1b4eaa61' added the ability to have a mode='direct' for
an iscsi disk volume.  It relied on virStorageTranslateDiskSourcePool
in order to copy any disk source pool authentication information to
the direct disk volume, but it neglected to also copy the 'secrettype'
field which ends up being used in the domain volume formatting code.
Adding a secrettype for this case will allow for proper formatting later
and allow disk snapshotting to work properly

Additionally libvirtd restart processing would fail to find the domain
since the translation processing code is run after domain xml processing,
so handle the the case where the authdef could have an empty secrettype
field when processing the auth and additionally ignore performing the
actual and expected auth secret type checks for a DISK_VOLUME since that
data will be reassembled later during translation processing of the
running domain.

During a review, I've noticed this error message that was eventually
produced when I was trying to define a domain:

error: invalid argument: could not find capabilities for arch=mips64el
domaintype=(null)

Look at the (null). Why is it there? Well, during XML parsing, we try
to look up the default emulator for given OS type and possibly virt
type too. And this is the problem, because if we don't want to look up
by virt type, a -1 is passed to note this fact. Later, the code
handles -1 just right. Except for error message. When it is
constructed (in a very fabulous way I must say), the value is compared
to zero, not -1. And since we don't have any translation from -1 to a
virt type string, we just print (null).

When attaching a scsi volume lun via the attach-device --config or
--persistent options, there was no translation of the source pool
like there was for the live path, thus the attempt to modify the config
would fail since not enough was known about the disk.

A variable can't be named system, obviously. Well, it can if the
compiler is new enough to distinguish a variable named system and a
function call system(). And some older systems, don't have wise
compiler.

If a macro has a string value, the @string attribute will contain the

 # define VIR_MIGRATE_PARAM_URI               "migrate_uri"

The virNetServer class has the ability to serialize its state
to a JSON file, and then re-load that data after an in-place
execve() call to re-connect to active file handles. This data
format is critical ABI that must have compatibility across
releases, so it should be tested...

By default, getaddrinfo() will return addresses for both
IPv4 and IPv6 if both protocols are enabled, and so the
RPC code will listen/connect to both protocols too. There
may be cases where it is desirable to restrict this to
just one of the two protocols, so add an 'int family'
parameter to all the TCP related APIs.
