Trivial fix changing printf() calls to vshPrint() where the ctl
variable is available.

Improves the help text for vol-path, vol-name, and vol-key, which
previously referred to volume UUIDs.

Addresses BZ # 598365.

Presently the vol-key command only supports being provided with
a volume path.

This patch adds support for providing it with a pool and volume
identifier pair as well.

    virsh # vol-key --pool <pool-name-or-uuid> <vol-name-or-path>

Justin Clift reported a problem with adding virStoragePoolIsPersistent
to virsh's pool-info command, resulting in a strange problem. Here's
an example:

    virsh # pool-create-as images_dir3 dir - - - - "/home/images2"
    Pool images_dir3 created

    virsh # pool-info images_dir3
    Name:           images_dir3
    UUID:           90301885-94eb-4ca7-14c2-f30b25a29a36
    State:          running
    Capacity:       395.20 GB
    Allocation:     30.88 GB
    Available:      364.33 GB

    virsh # pool-destroy images_dir3
    Pool images_dir3 destroyed

At this point the images_dir3 pool should be gone (because it was
transient) and we should be able to create a new pool with the same name:

    virsh # pool-create-as images_dir3 dir - - - - "/home/images2"
    Pool images_dir3 created

    virsh # pool-info images_dir3
    Name:           images_dir3
    UUID:           90301885-94eb-4ca7-14c2-f30b25a29a36
    error: Storage pool not found

The new pool got the same UUID as the first one, but we didn't specify
one. libvirt should have picked a random UUID, but it didn't.

It turned out that virStoragePoolIsPersistent leaks a reference to the
storage pool object (actually remoteDispatchStoragePoolIsPersistent does).
As a result, pool-destroy doesn't remove the virStoragePool for the
"images_dir3" pool from the virConnectPtr's storagePools hash on libvirtd's
side. Then the second pool-create-as get's the stale virStoragePool object
associated with the "images_dir3" name. But this object has the old UUID.

This commit ensures that all get_nonnull_* and make_nonnull_* calls for
libvirt objects are matched properly with vir*Free calls. This fixes the
reference leaks and the reported problem.

All remoteDispatch*IsActive and remoteDispatch*IsPersistent functions were
affected. But also remoteDispatchDomainMigrateFinish2 was affected in the
success path. I wonder why that didn't surface earlier. Probably because
domainMigrateFinish2 is executed on the destination host and in the common
case this connection is opened especially for the migration and gets closed
after the migration is done. So there was no chance to run into a problem
because of the leaked reference.

Commit b9efc7dc made virFileHasSuffix
case insensitive. Honor this in the tests by switching vmdk to VMDK.

Daniel's patch works with gcc and CFLAGS containing -O (the
autoconf default), but fails with non-gcc or with other
CFLAGS (such as -g), since c-ctype.h declares c_isdigit as
a macro only for certain compilation settings.

* src/Makefile.am (libvirt_parthelper_LDFLAGS): Add gnulib
library, for when c_isdigit is not a macro.
* src/storage/parthelper.c (main): Avoid out-of-bounds
dereference, noticed by Jim Meyering.

Disks with a trailing digit in their path (eg /dev/loop0 or
/dev/dm0) have an extra 'p' appended before the partition
number (eg, to form /dev/loop0p1 not /dev/loop01). Fix the
partition lookup to append this extra 'p' when required

* src/storage/parthelper.c: Add a 'p' before partition
  number if required

Otherwise, a malicious packet could cause a DoS via spurious
out-of-memory failure.

* src/uml/uml_driver.c (umlMonitorCommand): Validate that incoming
data is reliable before using it to allocate/dereference memory.
Don't report bogus errno on short read.
Reported by Jim Meyering.

Report that libvirt was built without that driver instead of
trying to connect to a libvirtd, when we know that this is
going to fail.

Otherwise this will segfault if DISPLAY is not defined.

Otherwise this will segfault if PATH is not defined.

This patch adds two new parameters to the vol-create-as command:

 --backing-vol <volume-name-or-key-or-path>
 --backing-vol-format <format-of-backing-vol>

  virsh # vol-create-as guest_images_lvm snapvol1 5G --backing-vol \
              rhel6vm1lun1
  Vol snapvol1 created

  virsh # vol-create-as image_dir qcow2snap2 5G --format qcow2 \
              --backing-vol imagevol1.qcow2 \
              --backing-vol-format qcow2
  Vol qcow2snap2 created

Additionally, the virsh man page update fixes incorrect snapshot
parameters that were included in my prior bulk volume command patch.

On Fedora 13 with sufficient mingw32-* packages installed, running
./autobuild.sh failed to cross-compile to mingw because
mingw32-pthreads installed a broken <pthread.h>.  With that
issue fixed, the build still failed due to use of O_SYNC.
Meanwhile, recent .spec.in changes got out of sync.

* bootstrap.conf (gnulib_modules): Add fcntl-h, for O_SYNC.
* .gnulib: Update to latest, to work around buggy pthreads-win32
library.
* bootstrap: Import latest from gnulib.
* mingw32-libvirt.spec.in: Distribute new file.

* src/util/threads.c (includes) [WIN32]: On mingw, favor native
threading over pthreads-win32 library.
* src/util/thread.h [WIN32] Likewise.

When a disk is on a root squashed NFS server, it may not be
possible to stat() the disk file in virCgroupAllowDevice.
The virStorageFileGetMeta method may also fail to extract
the parent backing store. Both of these errors have to be
ignored to avoid breaking NFS deployments

* src/qemu/qemu_driver.c: Ignore errors in cgroup setup to
   keep root squash NFS happy

With libvirt and virsh now being used for much more than Xen, this
patch removes the outdated reference to Xen in the file header.

Allow to specify a proxy to be used by libcurl.

Pass a struct containing the parameters instead of passing each
one individually. This make future extensions a bit simpler.

This patch also includes the new vol-pool command.

This patch adds a new "vol-pool" command to virsh, to round out the
identifier conversion functions for volumes in virsh.  Now it is
possible to work with volumes when starting from just a volume key
or volume path.

* tools/virsh.c (opts_create): Add --paused option.
(cmdCreate): Pass appropriate flag.
* tools/virsh.pod: Document it.

Some guests (eg with badly configured grub, or Windows' installation cd)
require quick response from the console user. That's why we have a
"launchPaused" option in vdsm.

To implement it via libvirt, we need to ask libvirt not to call
qemuMonitorStartCPUs() after starting qemu.  Calling virDomainStop
immediately after the domain is up is inherently raceful.

* src/qemu/qemu_driver.c (qemudStartVMDaemon): Add new parameter;
all callers adjusted.
(qemudDomainCreate): Implement support for new flag.

* include/libvirt/libvirt.h.in (virDomainCreateFlags): Add
VIR_DOMAIN_START_PAUSED.
* src/libvirt.c (virDomainCreateXML): Update documentation.

* This patch is a modification of a patch submitted by Nigel Jones.
  It fixes several memory leaks on device addition/removal:

1. Free the virNodeDeviceDefPtr in udevAddOneDevice if the return
   value is non-zero

2. Always release the node device reference after the device has been
   processed.

* Refactored for better readability per the suggestion of clalance

* Fix broken rng schema
* Add test input & output files

* Use virBufferEscapeString() per Dan B.

The virtio serial changes broke the test suite because they forgot
to add the new address attribute to the domain XML schema. The
xml2xml test also broke because the XML no longer roundtrips. This
is due to testing of auto-addition of <controller> elements. Split
that test case off into a separate XML file to avoid breakage

* docs/schemas/domain.rng: Allow port number for virtio serial addresses
* tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.args,
  tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.xml: Revert to
  a simple config to avoid breaking xml2xml test
* tests/qemuxml2argvdata/qemuxml2argv-channel-virtio-auto.xml,
  tests/qemuxml2argvdata/qemuxml2argv-channel-virtio-auto.args: Add
  complex test case for auto-controller addition for xml2argv test
* tests/qemuxml2argvtest.c: Add channel-virtio-auto test

A look at the QEMU source revealed the missing bits of info about
the VPC file format, so we can enable this now

* src/util/storage_file.c: Enable VPC format, providing version
  and disk size offset fields

When an attempt to hotplug a PCI device to a guest fails,
the device was left attached to pci-stub. It is neccessary
to reset the device and then attach it to the host driver
again.

* src/qemu/qemu_driver.c: Reattach PCI device to host if
  hotadd fails

The restore code is done in places where errors cannot be
raised, since they will overwrite over pre-existing errors.

* src/security/security_selinux.c: Only warn about failures
  in label restore, don't report errors
