Instead of automatically starting jobs at creation time via backup_start
et al, we'd like to return a job object pointer that can be started
manually at later point in time.
For now, add the block_job_start mechanism and start the jobs
automatically as we have been doing, with conversions job-by-job coming
in later patches.
Of note: cancellation of unstarted jobs will perform all the normal
cleanup as if the job had started, particularly abort and clean. The
only difference is that we will not emit any events, because the job
never actually started.

Commit 9ef2e93f introduced the concept of tagging ATAPI commands as
NONDATA, but this introduced a regression for certain commands better
described as CONDDATA. read_cd is such a command that both requires
a non-zero BCL if a transfer size is set, but is perfectly content to
accept a zero BCL if the transfer size is 0.
This test adds a regression test for the case where BCL and nb_sectors
are both 0.
Flesh out the CDROM tests by:
(1) Allowing the test to specify a BCL
(2) Allowing the buffer comparison test to compare a 0-size buffer
(3) Fix the BCL specification in libqos (It is LE, not BE)
(4) Add a nice human-readable message for future SCSI command additions

Commit 3ff2f67a changed bdrv_co_flush() so that no flush is issues if
the image hasn't been dirtied since the last flush. This is not quite
correct: The condition should be that the image hasn't been dirtied
since the last _successful_ flush. This patch changes the logic
accordingly.
Without this fix, subsequent bdrv_co_flush() calls would return success
without actually doing anything even though the image is still dirty.
The difference is visible in some blkdebug test cases where error
messages incorrectly disappeared after commit 3ff2f67a.

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.

(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.

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.

It is simpler and a bit faster, and QEMU does not need the contention
callbacks (and thus the fairness) anymore.

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.
Previously applied as a0710f7995 and

Now that we also support the "-prom-env" parameter for the pseries
machine, we can enable this test for this machine, too. Since booting
with TCG is rather slow with the pseries machine, we also enable
the "-nodefaults" parameter for this test now, so that SLOF does not
have to check that much devices during boot and thus runs a little
bit faster.

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.
