In this case, the virNetDevBandwidthPtr that is returned is not to a
region within the virDomainNetDef arg, but points elsewhere (the
NetDef has the pointer, not the entire object), so technically it's
not necessary to make the return value a const, but it's a bit
disingenuous to *not* do it.

The domain conf actual network def stores a <class id='3'/> element
separately from the <bandwidth>. The class ID should really just be
an attribute on the <bandwidth> element. We can't change existing
XML, and this isn't visible to users since it is internal XML only.
When we expose the new network port XML to users though, we should
get the design right.

The virNetDevBandwidthParse method uses the interface type to decide
whether to allow use of the "floor" parameter. Using the interface
type is not convenient as callers may not have that available, but
still wish to allow use of "floor". Switch to an explicit boolean
to control its usage.

Require that all headers are guarded by a symbol named
LIBVIRT_$FILENAME
where $FILENAME is the uppercased filename, with all characters
outside a-z changed into '_'.
Note we do not use a leading __ because that is technically a
namespace reserved for the toolchain.

In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.
In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.
With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to find the
author of a particular bit of code.
This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.
The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

The vhostuser is not a TAP. Therefore our QoS code is not able to
set any bandwidth. I don't really understand what I was thinking.

Since vhostuser type is really a tap that is just plugged into
different type of bridge, supporting QoS is trivial.

Since the code checks and handles NULL parameters, remove the NONNULL
from the prototype.
Also fix the comment in the source to reference the right name.

Since the code checks and handles a NULL 'node' before proceeding
there's no need for the prototype with the NONNULL(2).

Adds a new interface type using UDP sockets, this seems only applicable
to QEMU but have edited tree-wide to support the new interface type.
The interface type required the addition of a "localaddr" (local
address), this then maps into the following xml and qemu call.
<interface type='udp'>
<mac address='52:54:00:5c:67:56'/>
<source address='127.0.0.1' port='11112'>
<local address='127.0.0.1' port='22222'/>
</source>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</interface>
QEMU call:
-net socket,udp=127.0.0.1:11112,localaddr=127.0.0.1:22222
Notice the xml "local" entry becomes the "localaddr" for the qemu call.

There's this function virNetDevBandwidthParse which parses the
bandwidth XML snippet. But it's not clever much. For the
following XML it allocates the virNetDevBandwidth structure even
though it's completely empty:
<bandwidth>
</bandwidth>
Later in the code there are some places where we check if
bandwidth was set or not. And since we obtained pointer from the
parsing function we think that it is when in fact it isn't.

Ethernet interfaces in libvirt currently do not support bandwidth setting.
For example, following xml file for an interface will not apply these
settings to corresponding qdiscs.
<interface type="ethernet">
<mac address="02:36:1d:18:2a:e4"/>
<model type="virtio"/>
<script path=""/>
<target dev="tap361d182a-e4"/>
<bandwidth>
<inbound average="984" peak="1024" burst="64"/>
<outbound average="2000" peak="2048" burst="128"/>
</bandwidth>
</interface>

This is however supported only on domain interfaces with
type='network'. Moreover, target network needs to have at least
inbound QoS set. This is required by hierarchical traffic shaping.
From now on, the required attribute for <inbound/> is either 'average'
(old) or 'floor' (new). This new attribute can be used just for
interfaces type of network (<interface type='network'/>) currently.
