The %changelog entries in the RPM are just a poor immitation
of the release notes, which is not what %changelog section
is for. It should be reflecting changes in the RPM packaging,
not changes in the application releases. Further, this bogus
list of changes has to be manually deleted every time we sync
the RPM with Fedora. Remove them, since they serve no useful
purpose.

Rather than letting the configure script auto-detect features
we expect, use --with-xxx to explicitly mandate them. This
ensures that we get an error upfront when running configure,
rather than a failure later during build or RPM file packaging
time.

Commit id 'df1011ca' modified virStorageBackendDiskDeleteVol to use
"dmsetup remove --force" to remove the volume, but left things in an
inconsistent state since the partition still existed on the disk and
only the device mapper device (/dev/dm-#) was removed.

Prior to commit '1895b421' (or '1ffd82bb' and '471e1c4e'), this could
go unnoticed since virStorageBackendDiskRefreshPool wasn't called.
However, the pool would be unusable since the /dev/dm-# device would
be removed even though the partition was not removed unless a multipathd
restart reset the link. That would of course make the volume appear again
in the pool after a refresh or pool start after libvirt reload.

This patch removes the 'dmsetup' logic and re-implements the partition
deletion logic for device mapper devices. The removal of the partition
via 'parted rm --script #' will cause udev device change logic to allow
multipathd to handle removing the dm-* device associated with the partition.

Commit id '020135dc' didn't quite get the algorithm correct when a
device mapper source ended with a non numeric value (e.g. ends with
an alphabet value).

This patch modifies the 'part_separator' logic to add the "p" separator
to the attempted target path name only when specified as part_separator='yes'.

For a source name that already ends with a number, the logic doesn't change
as the part separator would need to be there.

For a source name that ends with something other than a number, this allows
the possibility that a "p" separator can be added. The default for one of
these source devices is to not add the separator.

The key for device mapper and the need for a partition separator "p" is
the presence of a number in the last character of the device name link
in /dev/mapper.  A name such as "/dev/mapper/mpatha1" would generate
a "/dev/mapper/mpatha1p1" partition, while "/dev/mapper/mpatha" would
generate partition "/dev/mapper/mpatha1". Similarly for a device
mapper entry not using friendly names or an alias, a device such as
"/dev/mapper/3600a0b80005b10ca00005ad656fd8d93" would generate a
paritition "/dev/mapper/3600a0b80005b10ca00005ad656fd8d93p1", while
a device such as "/dev/mapper/3600a0b80005b10ca00005e115729093f" would
generate a partition "/dev/mapper/3600a0b80005b10ca00005e115729093f1".
The long number is the WWID of the device. It's also possible to assign
an alias for a device mapper entry, that alias follows the same rules
with respect to ending with a number or not when adding a "p" to create
the target device path.

Prior to calling the 'refreshPool' during CreatePool or UploadPool
operations, we need to clear the pool; otherwise, the pool will
have duplicated entries.

Commit id 'dd519a29' caused a regression cloning a volume into a
logical pool by removing just the 'allocation' adjustment during
storageVolCreateXMLFrom. Combined with the change to not require the
new volume input XML to have a capacity listed (commit id 'e3f1d2a8')
left the possibility that a zero allocation value (e.g., not provided)
would create a thin/sparse logical volume. When a thin lv becomes fully
populated, then LVM sets the partition 'inactive' and the subsequent
fdatasync() fails.

Add a new 'has_allocation' flag to be set at XML parse time to indicate
that allocation was provided. This is done so that if it's not provided
the create-from code uses the capacity value since we document that if
omitted, the volume will be fully allocated at time of creation.

For a logical backend, that creation time is 'createVol', while for a
file backend, creation doesn't set the size, but the 'createRaw' called
during buildVolFrom will decide whether the file is sparse or not based
on the provided capacity and allocation value.

For volume clones that provide different allocation and capacity values
to allow for sparse files, there is no change.

Usage of this keyword in front of function declaration that is exported via a
header file is unnecessary, since internally, this has been the default for most
compilers for quite some time.

libvirt may automatically add a pci-root or pcie-root controller to a
domain, depending on the arch/machinetype, and it hopefully always
makes the right decision about which to add (since in all cases these
controllers are an implicit part of the virtual machine).

But it's always possible that someone will create a config that
explicitly supplies the wrong type of PCI controller for the selected
machinetype. In the past that would lead to an error later when
libvirt was trying to assign addresses to other devices, for example:

  XML error: PCI bus is not compatible with the device at
  0000:00:02.0. Device requires a PCI Express slot, which is not
  provided by bus 0000:00

(that's the error message that appears if you replace the pcie-root
controller in a Q35 domain with a pci-root controller).

This patch adds a check at the same place that the implicit
controllers are added (to ensure that the same logic is used to check
which type of pci root is correct). If a pci controller with index='0'
is already present, we verify that it is of the model that we would
have otherwise added automatically; if not, an error is logged:

  The PCI controller with index='0' must be " model='pcie-root' for
  this machine type, " but model='pci-root' was found instead.

This will be needed by the qemu driver in an upcoming patch.

Similar to "support Xen migration stream V2 in save/restore",
add support for indicating the migration stream version in
the migration code. To accomplish this, add a minimal migration
cookie in the libxl driver that is passed between source and
destination hosts. Initially, the cookie is only used in
the Begin and Prepare phases of migration to communicate the
version of the migration stream produced by the source.

Xen 4.6 introduced a new migration stream commonly referred to as
"migration V2". Xen 4.6 and newer always produce this new stream,
whereas Xen 4.5 and older always produce the legacy stream.
Support for migration stream V2 can be detected at build time with
LIBXL_HAVE_SRM_V2 from libxl.h. The legacy and V2 streams are not
compatible, but a V2 host can accept and convert a legacy stream.

Commit e7440656 changed the libxl driver to use the lowest libxl
API version possible (version 0x040200) to ensure the driver
builds against older Xen releases. The old 4.2 restore API does
not support specifying a stream version and assumes a legacy
stream, even if the incoming stream is migration V2. Thinking it
has been given a legacy stream, libxl will fail to convert an
incoming stream that is already V2, which causes the entire
restore operation to fail. Xen's libvirt-related OSSTest has been
failing since commit e7440656 landed in libvirt.git master. One
of the more recent failures can be seen here

http://lists.xenproject.org/archives/html/xen-devel/2016-05/msg00071.html

This patch changes the call to libxl_domain_create_restore() to
include the stream version if LIBXL_HAVE_SRM_V2 is defined. The
version field of the libxlSavefileHeader struct is also updated
to '2' when LIBXL_HAVE_SRM_V2 is defined, ensuring the stream
version in the header matches the actual stream version produced
by Xen. Along with bumping the libxl API requirement to 0x040400,
this patch fixes save/restore on a migration V2 Xen host.

Oddly, migration has never used the libxlSavefileHeader. It
handles passing configuration in the Begin and Prepare phases,
and then calls libxl directly to transfer domain state/memory
in the Perform phase. A subsequent patch will add stream
version handling in the Begin and Prepare phase handshaking,
which will fix the migration related OSSTest failures.

In LIBXL_API_VERSION 0x040400, the libxl_domain_create_restore API
gained a parameter for specifying restore parameters. Switch to
using version 0x040400, which will be useful in a subsequent commit
to specify the Xen migration stream version when restoring.
