8b8a61ad8c s390x: Introduce S390MachineClass
As we now have the new machine definitions, that let us disable/enable
machine options more easily, we need a way to save them and make them
publicly available.

The new s390-virtio-ccw.h header exports the s390 ccw machine state
and class, so they can be easily used in other C files.

7ef295ea5b loader: Add data swap option to load-elf
Some CPUs are of an opposite data-endianness to other components in the
system. Sometimes elfs have the data sections layed out with this CPU
data-endianness accounting for when loaded via the CPU, so byte swaps
(relative to other system components) will occur.

The leading example, is ARM's BE32 mode, which is is basically LE with
address manipulation on half-word and byte accesses to access the
hw/byte reversed address. This means that word data is invariant
across LE and BE32. This also means that instructions are still LE.
The expectation is that the elf will be loaded via the CPU in this
endianness scheme, which means the data in the elf is reversed at
compile time.

As QEMU loads via the system memory directly, rather than the CPU, we
need a mechanism to reverse elf data endianness to implement this
possibility.

Only one channel report word (crw) may be pending if there is
event-information pending.

This patch introduces a bool-type field 'sei_pending' for the
channel subsystem, which indicates whether there are pending events.
It is set when event information is made pending and the crw
generated, and cleared after the guest has collected all pending
event information. A crw is not generated if this flag had already
been set.

193227f9e5 error: Use error_report_err() instead of monitor_printf()
Both error_report_err() and monitor_printf() print to the same
destination when monitor_printf() is used correctly, i.e. within an
HMP monitor.  Elsewhere, monitor_printf() does nothing, while
error_report_err() reports to stderr.

Most changed functions are HMP command handlers.  These should only
run within an HMP monitor.  The one exception is bdrv_password_cb(),
which should also only run within an HMP monitor.

Four command handlers prefix the error message with the command name:
balloon, migrate_set_capability, migrate_set_parameter, migrate.
Pointless, drop.

Unlike monitor_printf(), error_report_err() uses the error whole
instead of just its message obtained with error_get_pretty().  This
avoids suppressing its hint (see commit 50b7b00).  Example:

    (qemu) device_add ivshmem,id=666
    Parameter 'id' expects an identifier
    Identifiers consist of letters, digits, '-', '.', '_', starting with a letter.
    Try "help device_add" for more information

The "Identifiers consist of..." line is new with this patch.

11380b3619 virtio: handle non-virtio-1-capable backend for ccw
If you run a qemu advertising VERSION_1 with an old kernel where
vhost did not yet support VERSION_1, you'll end up with a device
that is {modern pci|ccw revision 1} but does not advertise VERSION_1.
This is not a sensible configuration and is rejected by the Linux
guest drivers.

To fix this, add a ->post_plugged() callback invoked after features
have been queried that can handle the VERSION_1 bit being withdrawn
and change ccw to fall back to revision 0 if VERSION_1 is gone.

Note that pci is _not_ fixed; we'll need to rethink the approach
for the next release but at least for pci it's not a regression.

f0a399dbae s390x/pci: fix up IOMMU size
Present code uses @size==UINT64_MAX to initialize IOMMU. It infers that it
can map any 64-bit IOVA whatsoever. But in fact, the largest DMA range for
each PCI Device on s390x is from ZPCI_SDMA_ADDR to ZPCI_EDMA_ADDR. The largest
value is returned from hardware, which is to indicate the largest range
hardware can support. But the real IOMMU size for specific PCI Device is
obtained once qemu intercepts mpcifc instruction that guest is requesting a
DMA range for that PCI Device. Therefore, before intercepting mpcifc instruction,
qemu cannot be aware of the size of IOMMU region that guest will use.

Moreover, iommu replay during device initialization for the whole region in
4k steps takes a very long time.

In conclusion, this patch intializes IOMMU region for each PCI Device when
intercept mpcifc instruction which is to register DMA range for the PCI Device.
And then, destroy IOMMU region when guest wants to deregister IOAT.

3c4c694c7c s390: deprecate the non-ccw machine in 2.5
The non-ccw machine for s390 (s390-virtio) is not very well maintained
and caused several issues in the past:
- aliases like virtio-blk did not work for s390
- virtio refactoring failed due to long standing bugs (e.g.see
commit cb927b8a "s390-virtio: Accommodate guests using virtqueues too early")
- some features like memory hotplug will cause trouble due to virtio storage
  being above guest memory
- the boot loader bios no longer seems to work. the source code of that
  loader is also no longer maintained

2.4 changed the default to the ccw machine, let's deprecate the old
machine for 2.5.
