commit 5325123d235deb07f39b73c06a7d9ab6494fa2c8

libxl: support Xen migration stream V2 in save/restore
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.

libxl: support migration stream V2 in migration
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.

libxl: switch to using libxl_domain_create_restore from v4.4 API
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.
