This reworks the image loading on s390.
Newer kernels will not always have a 0dd0 (basr 13,0) at address 0x10000.
We must not rely on specific code at certain addresses. This check was
introduced to warn users that tried to load vmlinux, since ELF loading
was not supported. Lets wire that up. If elf loading fails, we assume
that this is a standard kernel image and load that via load_image_targphys.
This patch also changes all other users of load_image to
load_image_targphys to be consistent. (the elf loader registers the kernel
as rom).

memory: fix I/O port aliases
Commit
e58ac72b6a0 ("ioport: change portio_list not to use
memory_region_set_offset()") started using aliases of I/O memory
regions. Since the IORange used for the I/O was contained in the
target region, the alias information (specifically, the offset
into the region) was lost. This broke -vga std.
Fix by allocating an independent object to hold the IORange and
also the new offset.
Note that I/O memory regions were conceptually broken wrt aliases
in a different way: an alias can cause the same region to appear
twice in an address space, but we had just one IORange to service it.
This patch fixes that problem as well, since we can now have multiple
IORange/MemoryRegion associations.

qemu-iotests: add iotests Python module
Block layer tests that involve QMP commands rather than qemu-img or
qemu-io are not well-suited for shell scripting. This patch adds a
Python module which allows tests to be written in Python instead.
The basic API is:
VM - class for launching and interacting with a VM
QMPTestCase - abstract base class for tests that use QMP
qemu_img() - wrapper function for invoking qemu-img
qemu_io() - wrapper function for invoking qemu-io
imgfmt - the image format under test (e.g. qcow2, qed)
test_dir - scratch directory path for temporary files
main() - entry point for running tests

QMP: Add qmp command for blockdev-group-snapshot-sync
This adds the QMP command for blockdev-group-snapshot-sync. It
takes an array in as the input, for the argument devlist. The
array consists of the following elements:
+ device: device to snapshot. e.g. "ide-hd0", "virtio0"
+ snapshot-file: path & file for the snapshot image. e.g. "/tmp/file.img"
+ format: snapshot format. e.g., "qcow2". Optional

qapi: Introduce blockdev-group-snapshot-sync command
This is a QAPI/QMP only command to take a snapshot of a group of
devices. This is similar to the blockdev-snapshot-sync command, except
blockdev-group-snapshot-sync accepts a list devices, filenames, and
formats.
It is attempted to keep the snapshot of the group atomic; if the
creation or open of any of the new snapshots fails, then all of
the new snapshots are abandoned, and the name of the snapshot image
that failed is returned. The failure case should not interrupt
any operations.
Rather than use bdrv_close() along with a subsequent bdrv_open() to
perform the pivot, the original image is never closed and the new
image is placed 'in front' of the original image via manipulation
of the BlockDriverState fields. Thus, once the new snapshot image
has been successfully created, there are no more failure points
before pivoting to the new snapshot.
This allows the group of disks to remain consistent with each other,
even across snapshot failures.
