  s390: Rework kernel loading: supports elf and newer kernels

Provides a file naming scheme consistent with other targets.
Signed-off-by: NLluís Vilanova <vilanova@ac.upc.edu>

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).

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.
Signed-off-by: NAvi Kivity <avi@redhat.com>

Previously all callers had a containing object with a destructor that
could be used to trigger cleanup of the IORange objects (typically
just freeing the containing object), but a forthcoming memory API
change doesn't fit this pattern.  Rather than setting up a new global
table, extend the ioport system to support destructors.

flush_icache_range takes two address parameters which must be large
enough to address any address of the host.

For hosts with sizeof(unsigned long) == sizeof(void *), this patch
changes nothing. All currently supported hosts fall into this category.

For w64 hosts, sizeof(unsigned long) is 4 while sizeof(void *) is 8,
so the use of tcg_target_ulong is needed for i386 and tci (the tcg

Block layer tests that involve QMP commands rather than qemu-img or

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)

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
