The 'trang' utility, which is able to transform '.rng' files into
'.rnc' files, reported some errors in our schemas that weren't caught
by the tools we use in the build.  I haven't added a test for this,
but the validity can be checked by the following command:

trang -I rng -O rnc domain.rng domain.rnc

There were unescaped minuses in regular expressions and we were
constraining int (which is by default in the range of [-2^31;2^31-1]
to maximum of 2^32.  But what we wanted was exactly an unsignedInt.

Use the exclusive parameter checker and touch up some parts to simplify
code.

The check is done on the "--paused" flag but the error message stated
"--saved"

Use the new helpers to determine mutually exclusive options and touch up
some parts to simplify the code.

Simplify error handling and mutually exclusive option checking.

This patch adds three macros to the virsh source tree that help to
easily check for mutually exclusive parameters.

VSH_EXCLUSIVE_OPTIONS_EXPR has four arguments, two expressions to check
and two names of the parameters to print in the message.

VSH_EXCLUSIVE_OPTIONS is more specific and check the command structure
for the parameters using vshCommandOptBool.

VSH_EXCLUSIVE_OPTIONS_VAR is meant to check boolean variables with the
same name as the parameters.

The addition of emulator pinning APIs didn't think of doing the right
job with python APIs for them. The default generator produced unusable
code for this.

This patch switches to proper code as in the case of domain Vcpu pining.
This change can be classified as a python API-breaker but in the state
the code was before I doubt anyone was able to use it successfully.

When the blockjob fails for some reason an event is emitted but the disk
wasn't unmarked as being part of a active block copy operation.

Some code mistakenly called virIdentityOnceInit directly
instead of virIdentityInitialize(). This meant that one-time
initializer was run many times with predictably bad results.

The VIR_ERR_NO_SUPPORT error code is reserved for cases where an
API is not implemented in a driver. It definitely should not be
used when an API execution fails due to unsupported operation.

The recent commit moved some of the use of libnuma out of the
driver code, and into src/util/. It did not, however, update
libvirt_util.la to link against libnuma. This caused linkage
failure with virt-aa-helper, since nothing else caused libnuma
to be pulled onto the linker command line.

The fix removes all reference to NUMACTL_LIBS/CFLAGS from the
various modules in src/Makefile.am and just adds them to the
libvirt_util.la module, which everything else depends on.

Technically a build-breaker fix, but wanted to wait for feedback
on this

We should record the new disk src in the shared disk table for
updating disk (CD-ROM or Floppy) API. Fortunately, we only allow
to update the disk source now, otherwise we might also want to
set the unpriv_sgio setting.

For example:
 >>> dom.memoryStats()
 libvir: QEMU Driver error : Requested operation is not valid:\
         domain is not running

There are six such python API functions like so.
The root reason is that generator.py script checks the type of return
value of a python stub function defined in libvirt-api.xml or
libvirt-override-api.xml to see whether to add the raise clause or not
in python wrapper code in libvirt.py.

The type of return value is supposed to be C types.
For those stub functions which return python non-integer data type like
string, list, tuple, dictionary, the existing type in functions varies
from each other which leads problem like this.

Currently, in generator.py, it maintains a buggy whitelist for stub functions
returning a list type. I think it is easy to forget adding new function name
in the whitelist.

This patch makes the value of type consistent with C type "char *"
in libvirt-override-api.xml. For python, any of types could be printed
as string, so I choose "char *" in this case. And the comment in xml
could explain it when adding new function definition.

      <function name='virNodeGetCPUStats' file='python'>
        ...
 -      <return type='virNodeCPUStats' info='...'/>
 +      <return type='char *' info='...'/>
        ...
      </function>

The "dtb" option sets the filename for the device tree.
If without this option support, "-dtb file" will be converted into
<qemu:commandline> in domain XML file.
For example, '-dtb /media/ram/test.dtb' will be converted into
  <qemu:commandline>
    <qemu:arg value='-dtb'/>
    <qemu:arg value='/media/ram/test.dtb'/>
  </qemu:commandline>

This is not very friendly.
This patchset add special <dtb> tag like <kernel> and <initrd>
which is easier for user to write domain XML file.
  <os>

virStorageBackendRBDRefreshPool() first allocates an array big enough
to hold 1024 names, then calls rbd_list(), which returns ERANGE if the
array isn't big enough. When that happens, the VIR_ALLOC_N is called
again with a larger size. Unfortunately, the original array isn't
freed before allocating a new one.

There was a 2 word sentence 'remote server' which is a left-over
from copy and paste.

Because of a wrong copy and paste, the documentation was saying that
'path' is the path to a block device node while it's a path to a
directory.

The LXC controller is closing loop devices as soon as the
container has started. This is fine if the loop device
was setup as a mounted filesystem, but if we're just passing
through the loop device as a disk, nothing else is keeping
it open. Thus we must keep the loop device FDs open for as
long the libvirt_lxc process is running.

Currently the LXC controller creates the cgroup, configures the
resources and adds the task all in one go. This is not sufficiently
flexible for the forthcoming NBD integration. We need to make sure
the NBD process gets into the right cgroup immediately, but we can
not have limits (in particular the device ACL) applied at the point
where we start qemu-nbd. So create a virLXCCgroupCreate method
which creates the cgroup and adds the current task to be called
early, and leave virLXCCgroupSetup to only do resource config.
