xl and xm differ a bit in how <os> configuration is represented.
E.g. xl config supports <os><nvram .../></os> via its "bios"
setting.

Move the xenParseOS and xenFormatOS functions from xen_common.c
and copy to xen_xl.c and xen_xm.c so they can be customized for
xm vs xl config.  An unfortunate fallout is reordering of entries
in the test config files.

The <inbound/> element to <bandwidth/> has several attributes from
which two are mandatory. Well, from two at least one has to be
present: @average or @floor or both. Instead of inventing crazy RNG
schema, let's make all the attributes optional there and rely on our
parsing code to correctly handle the situation.

These cannot be represented in XML.

We have been stripping them, but only if the string had
characters that needed escaping: <>"'&

Extend the strcspn check to include control codes, and strip
them even if we don't do any escaping.

https://bugzilla.redhat.com/show_bug.cgi?id=1184131
https://bugzilla.redhat.com/show_bug.cgi?id=1066564

Add virStringHasControlChars that checks if the string has
any control characters other than \t\r\n,
and virStringStripControlChars that removes them in-place.

For reuse with other Strip* functions.

In one of my previous commits (49ed6cff) I've introduced a test
among with some files stored under virnetdevtestdata folder.
While this works perfectly within a git tree, the folder was not
getting into .tar.gz and therefore the dist-check would fail.

Commit id 'b77ce18a' added a new bitmap, but neglected to virBitmapFree it

Add FromVol at the end. This function will create the qemu-img
command line from volume definitions and check them.

This patch adds checks for empty bitmaps right after the calls of
virBitmapParse. These only include spots where set API's are called and
where domain's XML is parsed.
Also, it partially reverts commit 983f5a which added a check for
invalid nodeset "0,^0" into virBitmapParse function. This change broke
the logic, as an empty bitmap should not cause an error.

Request that the number be parsed as decimal, to allow 08

We don't format the default '-1' fields back.

are needed there.

There are two leftover unused variables. Remove them and clean up the
fallout of the change.

rfc3986 states that the separator in URI path is a single slash.
Multiple slashes may potentially lead to different resources and thus we
should not remove them.

Add test infrastructure for virFileSanitizePath so that it can be
sensibly refactored later.

This new internal API checks if given CGroup controller is
available.  It is going to be needed later when we need to make a
decision whether pin domain memory onto NUMA nodes using cpuset
CGroup controller or using numa_set_membind().

In virDomainVirtioSerialAddrNext, add another controller
if we've exhausted all ports of the existing controllers.

https://bugzilla.redhat.com/show_bug.cgi?id=1076708

Instead of always using controller 0 and incrementing port number,
respect the maximum port numbers of controllers and use all of them.

Ports for virtio consoles are quietly reserved, but not formatted
(neither in XML nor on QEMU command line).

Also rejects duplicate virtio-serial addresses.
https://bugzilla.redhat.com/show_bug.cgi?id=890606
https://bugzilla.redhat.com/show_bug.cgi?id=1076708

Test changes:
* virtio-auto.args
  Filling out the port when just the controller is specified.
  switched from using
    maxport + 1
  to:
    first free port on the controller
* virtio-autoassign.args
  Filling out the address when no <address> is specified.
  Started using all the controllers instead of 0, also discards
  the bus value.
* xml -> xml output of virtio-auto
  The port assignment is no longer done as a part of XML parsing,
  so the unspecified values stay 0.

Add a test to demonstrate the effect of automatic virtio-serial
address assignment.

The 7c3c7f21 and f5c2d6 commits introduced a nodeinfo test.
In order to do that, some parts of sysfs had to be copied.
However, sysfs is full of symlinks, so during copying some
symlinks broke. Remove them, as on different systems they can
point to different files or be broken. At the same time, we don't
need all files added in those commits. For instance we don't care
about 'uevent' files, 'power' folders, and others.

QEMU 2.3 adds these new models to cover Haswell and Broadwell CPUs with

Recently we've fixed a bug where the status XML could not be parsed as
the parser used absolute path XPath queries. This test enhancement tests
all XML files used in the qemu-xml-2-xml test as a part of a status XML
snippet to see whether they are parsed correctly. The status XML-2-XML is
currently tested in 223 cases with this patch.

The current auto-indentation buffer code applies indentation only on
complete strings. To allow adding a string containing newlines and
having it properly indented this patch adds virBufferAddStr.

To allow adding more tests, refactor the XML-2-XML test so that the
files are not reloaded always and clarify the control flow.

Result of this changes is that the active and inactive portions of the
XML are tested in separate steps rather than one test step.

Function virQEMUCapsInitGuestFromBinary detect kvm support by testing

Add support to start qemu instance with 'pc-dimm' device. Thanks to the
refactors we are able to reuse the existing function to determine the
parameters.

This patch adds code that parses and formats configuration for memory
devices.

A simple configuration would be:
<memory model='dimm'>
  <target>
    <size unit='KiB'>524287</size>
    <node>0</node>
  </target>
</memory>

A complete configuration of a memory device:
<memory model='dimm'>
  <source>
    <pagesize unit='KiB'>4096</pagesize>
    <nodemask>1-3</nodemask>
  </source>
  <target>
    <size unit='KiB'>524287</size>
    <node>1</node>
  </target>
</memory>

This patch preemptively forbids use of the <memory> device in individual
drivers so the users are warned right away that the device is not
supported.
