d2d1dec1f5 util: Fix naming in util/virnodesuspend
That file has only two exported files and each one of them has
different naming.  virNode is what all the other files use, so let's
use it.  It wasn't used before because the clash with public API
naming, so let's fix that by shortening the name (there is no other
private variant of it anyway).

26ae4e482a Remove src/nodeinfo
There is no "node driver" as there was before, drivers have to do
their own ACL checking anyway, so they all specify their functions and
nodeinfo is basically just extending conf/capablities.  Hence moving
the code to src/conf/ is the right way to go.

Also that way we can de-duplicate some code that is in virsysfs and/or
virhostcpu that got duplicated during the virhostcpu.c split.  And
Some cleanup is done throughout the changes, like adding the vir*
prefix etc.

bdcb199532 Move src/fdstream to src/util/virfdstream
There is no reason for it not to be in the utils, all global symbols
under that file already have prefix vir* and there is no reason for it
to be part of DRIVER_SOURCES because that is just a leftover from
older days (pre-driver modules era, I believe).

dd8ac030fb util: add MTU arg to virNetDevTapCreateInBridgePort()
virNetDevTapCreateInBridgePort() has always set the new tap device to
the current MTU of the bridge it's being attached to. There is one
case where we will want to set the new tap device to a different
(usually larger) MTU - if that's done with the very first device added
to the bridge, the bridge's MTU will be set to the device's MTU. This
patch allows for that possibility by adding "int mtu" to the arg list
for virNetDevTapCreateInBridgePort(), but all callers are sending -1,
so it doesn't yet have any effect.

Since the requested MTU isn't necessarily what is used in the end (for
example, if there is no MTU requested, the tap device will be set to
the current MTU of the bridge), and the hypervisor may want to know
the actual MTU used, we also return the actual MTU to the caller (if
actualMTU is non-NULL).

08ea852c25 nodeinfo: remove sysfs_prefix from all methods
Nearly all the methods in the nodeinfo file are given a
'const char *sysfs_prefix' parameter to override the
default sysfs path (/sys/devices/system). Every single
caller passes in NULL for this, except one use in the
unit tests. Furthermore this parameter is totally
Linux-specific, when the APIs are intended to be cross
platform portable.

This removes the sysfs_prefix parameter and instead gives
a new method linuxNodeInfoSetSysFSSystemPath for use by
the test suite.

For two of the methods this hardcodes use of the constant
SYSFS_SYSTEM_PATH, since the test suite does not need to
override the path for thos methods.

9b111048ad Clean up redundant usage of virDomainObjSetDefTransient
Commit 45ec297d from November 2010:
    Make state driver device hotplug/update actually transient
added virDomainObjSetDefTransient calls to the domain startup
function in several drivers.

In November 2011, commit 8866eed:
    Set aliases for LXC/UML console devices
added a call earlier in the startup function, without removing the
existing ones.

Also, in the UML driver it seems the function never did anything
useful - vm->def->id is set asynchronnously in umlNotifyEvent.
At the time of calling virDomainObjSetDefTransient with live=false,
vm->def->id was likely still -1, making the call a no-op.

185d13b1b0 conf: refactor checking for unsupported memory devices
Introduce a helper to check supported device and domain config and move
the memory hotplug checks to it.

The advantage of this approach is that by default all new features are
considered unsupported by all hypervisors unless specifically changed
rather than the previous approach where every hypervisor would need to
declare that a given feature is unsupported.

cc48d3a122 util: Add a return value to void hash iterators
Our existing virHashForEach method iterates through all items disregarding the
fact, that some of the iterators might have actually failed. Errors are usually
dispatched through an error element in opaque data which then causes the
original caller of virHashForEach to return -1. In that case, virHashForEach
could return as soon as one of the iterators fail. This patch changes the
iterator return type and adjusts all of its instances accordingly, so the
actual refactor of virHashForEach method can be dealt with later.

c99b8cec82 virDomainCreateXML: Make domain definition transient
https://bugzilla.redhat.com/show_bug.cgi?id=871452

So, you want to create a domain from XML. The domain already
exists in libvirt's database of domains. It's okay, because name
and UUID matches. However, on domain startup, internal
representation of the domain is overwritten with your XML even
though we claim that the XML you've provided is a transient one.
The bug is to be found across nearly all the drivers.
Le sigh.

37405b9109 virDomainCreateXML: Don't remove persistent domains on error
https://bugzilla.redhat.com/show_bug.cgi?id=871452

Okay, so we allow users to 'virsh create' an already existing
domain, providing completely different XML than the one stored in
Libvirt. Well, as long as name and UUID matches. However, in some
drivers the code that handles errors unconditionally removes the
domain that failed to start even though the domain might have
been persistent. Fortunately, the domain is removed just from the
internal list of domains and the config file is kept around.

Steps to reproduce:

1) virsh dumpxml $dom > /tmp/dom.xml
2) change XML so that it is still parse-able but won't boot, e.g.
change guest agent path to /foo/bar
3) virsh create /tmp/dom.xml
4) virsh dumpxml $dom
5) Observe "No such domain" error

5c668a78d8 qemu: add udp interface support
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.
