I misunderstood the workings of the power settings, the power off
is a force off operation and there needs to be a separate graceful

To make it a little more obvious which functions are intended to be
public interface and which are intended to be for use only by jobs
themselves, split the interface into "public" and "private" files.
Convert blockjobs (e.g. block/backup) to using the private interface.
Leave blockdev and others on the public interface.
There are remaining uses of private state by qemu-img, and several
cases in blockdev.c and block/io.c where we grab job->blk for the
purposes of acquiring an AIOContext.
These will be corrected in future patches.

ppc patch queue 2016-10-28
This pull request supersedes and extends the one from 2016-10-26
(which had a build bug).
Highlights:
* SLOF (pseries guest firmware) update
* Enable a number of extra testcases on ppc / pseries
* Added the 'powernv' machine type
- Almost enough to be minimally usable
- But still missing necessary interrupt controller updates
* Cleanup and consolidation of NVRAM handling on several platforms
with related firmware
* Substantial cleanup to device tree construction
* Some more POWER9 instruction emulation
* Cleanup to handling of pseries option vectors and CAS reboot
handling (host/guest feature negotiation mechanism)
* Significant cleanups to handling of PCI devices in test cases
* New hotplug event infrastructure
* Memory hot unplug support for pseries
* Several bug fixes
The NVRAM cleanup affects some Sun sparc platforms as well as ppc
ones, but have been tested by the sparc maintainer (Mark Cave-Ayland).
The test additions also include substantial general changes to the
test framework that aren't strictly ppc related. They don't seem to
break tests on other platforms, they're for the benefit of enabling
tests on ppc and there isn't a specific maintainer for them, so
they're included in this tree.

This is the first step towards having fine-grained critical sections in
dataplane threads, which will resolve lock ordering problems between
address_space_* functions (which need the BQL when doing MMIO, even
after we complete RCU-based dispatch) and the AioContext.
Because AioContext does not use contention callbacks anymore, the
unit test has to be changed.

The usual use model for the libqos PCI functions is to map a specific PCI
BAR using qpci_iomap() then pass the returned token into IO accessor
functions. This, and the fact that iomap() returns a (void *) which
actually contains a PCI space address, kind of suggests that the return
value from iomap is supposed to be an opaque token.
..except that the callers expect to be able to add offsets to it. Which
also assumes the compiler will support pointer arithmetic on a (void *),
and treat it as working with byte offsets.
To clarify this situation change iomap() and the IO accessors to take
a definitely opaque BAR handle (enforced with a wrapper struct) along with
an offset within the BAR. This changes both the functions and all the
callers.
There were a number of places that checked if iomap() returned non-NULL,
and or initialized it to NULL before hand. Since iomap() already assert()s
if it fails to map the BAR, these tests were mostly pointless and are
removed.

In a couple of places ahci-test makes assumptions about how the tokens
returned from qpci_iomap() are formatted in ways it probably shouldn't.
First in verify_state() it uses a non-NULL token to indicate that the AHCI
device has been enabled (part of enabling is to iomap()). This changes it
to use an explicit 'enabled' flag instead.
Second, it uses the fact that the token contains a PCI address, stored when
the BAR is mapped during initialization to check that the BAR has the same
value after a migration. This changes it to explicitly read the BAR
register before and after the migration and compare.
Together, these changes will make the test more robust against changes to
the internals of the libqos PCI layer.

ivshmem implements a block of shared memory in a PCI BAR. Currently our

Currently the libqos PCI layer includes accessor helpers for 8, 16 and 32
bit reads and writes. It's likely that we'll want 64-bit accesses in the
future (plenty of modern peripherals will have 64-bit reigsters). This
adds them.
For PIO (not MMIO) accesses on the PC backend, this is implemented as two
32-bit ins or outs. That's not ideal but AFAICT x86 doesn't have 64-bit
versions of in and out.
This patch also converts the single current user of 64-bit accesses -
virtio-pci.c to use the new mechanism, rather than a sequence of 8 byte

In the libqos PCI code we now have accessors both for registers (byte
significance preserving) and for streaming data (byte address order
preserving). These exist in both the interface for qtest drivers and in
the machine specific backends.
However, the register-style accessors aren't actually necessary in the
backend. They can be implemented in terms of the byte address order
preserving accessors by the libqos wrappers. This works because PCI is
always little endian.
This does assume that the back end byte address order preserving accessors
will perform the equivalent of a single bus transaction for short lengths.
This is the case, and in fact they currently end up using the same
cpu_physical_memory_rw() implementation within the qtest accelerator.

Currently PCI memory (aka MMIO) space is accessed via a set of readb/writeb
style accessors. This is what we want for accessing discrete registers of
a certain size. However, there are a few cases where we instead need a
"bag of bytes" style streaming interface to PCI MMIO space. This can be
either for streaming data style registers or when there's actual memory
rather than registers in PCI space, for example frame buffers or ivshmem.
This patch adds backend callbacks, and libqos wrappers for this type of
byte address order preserving accesses.

The usual model for PCI IO with libqos is to use qpci_iomap() to map a
specific BAR for a PCI device, then perform IOs within that BAR using
qpci_io_{read,write}*().
However, certain devices also have legacy PCI IO. In this case, instead of
(or as well as) being accessed via PCI BARs, the device can be accessed
via certain well-known, fixed addresses in PCI IO space.
Two existing tests use legacy PCI IO, and take different flawed approaches
to it:
* tco-test manually constructs a tco_io_base value instead of calling
qpci_iomap(), which assumes internal knowledge of the structure of
the value it shouldn't have
* ide-test uses direct in*() and out*() calls instead of using
qpci_io_*() accessors, meaning it's not portable to non-x86 machine
types.
This patch implements a new qpci_iomap_legacy() interface which gets a
handle in the same format as qpci_iomap() but refers to a region in
the legacy PIO space. For a device which has the same registers
available both in a BAR and in legacy space (quite common), this
allows the same test code to test both options with just a different
iomap() at the beginning.

The PCI backends in libqos each supply an iomap() and iounmap() function
which is used to set up a specified PCI BAR. But PCI BAR allocation takes
place entirely within PCI space, so doesn't really need per-backend
versions. For example, Linux includes generic BAR allocation code used on
platforms where that isn't done by firmware.
This patch merges the BAR allocation from the two existing backends into a
single simplified copy. The back ends just need to set up some parameters
describing the window of PCI IO and PCI memory addresses which are
available for allocation. Like both the existing versions the new one uses
a simple bump allocator.
Note that (again like the existing versions) this doesn't really handle
64-bit memory BARs properly. It is actually used for such a BAR by the
ivshmem test, and apparently the 32-bit MMIO BAR logic is close enough to
work, as long as the BAR isn't too big. Fixing that to properly handle
64-bit BAR allocation is a problem for another time.

The PCI IO space (aka PIO, aka legacy IO) and PCI memory space (aka MMIO)
are distinct address spaces by the PCI spec (although parts of one might be
aliased to parts of the other in some cases).
However, qpci_io_read*() and qpci_io_write*() can perform accesses to
either space depending on parameter. That's convenient for test case
drivers, since there are a fair few devices which can be controlled via
either a PIO or MMIO BAR but with an otherwise identical driver.
This is implemented by having addresses below 64kiB treated as PIO, and
those above treated as MMIO. This works because low addresses in memory
space are generally reserved for DMA rather than MMIO.
At the moment, this demultiplexing must be handled by each PCI backend
(pc and spapr, so far). There's no real reason for this - the current
encoding is likely to work for all platforms, and even if it doesn't we
can still use a more complex common encoding since the value returned from
iomap are semi-opaque.
This patch moves the demultiplexing into the common part of the libqos PCI
code, with the backends having simpler, separate accessors for PIO and
MMIO space. This also means we have a way of explicitly accessing either
space if it's necessary for some special case.

The 'addr' parameter to qvirtio_config_read*() doesn't have a consistent
meaning: when using the virtio-pci versions, it's a full PCI space address,
but for virtio-mmio, it's an offset from the device's base mmio address.
This means that the callers need to do different things to calculate the
addresses in the two cases, which rather defeats the purpose of function
pointer backends.
All the current users of these functions are using them to retrieve
variables from the device specific portion of the virtio config space.
So, this patch alters the semantics to always be an offset into that
device specific config area.

This patch replaces calls to qtest_start() and qtest_end() by
calls to qtest_pc_boot() and qtest_shutdown().
This allows to initialize memory allocator and PCI interface
functions. This will ease to enable virtio tests on other
architectures by only adding a specific qtest_XXX_boot() (like
qtest_spapr_boot()).

Move the definition to libqos/virtio.h as it must be used
only with virtio functions.
Add a QVirtioDevice parameter as it will be needed to
know if the virtio device is using virtio 1.0 specification
and thus is always little-endian (to do)

qtest_spapr_boot()/qtest_pc_boot()/qtest_boot() call qtest_vboot()
and qtest_vboot() calls g_malloc(),
and g_malloc() never fails:
if memory allocation fails, the application is terminated.
