Aborting on error in bdrv_append() isn't correct. This patch fixes it
and lets the callers handle failures.
Test case 085 needs a reference output update. This is caused by the
reversed order of bdrv_set_backing_hd() and change_parent_backing_link()
in bdrv_append(): When the backing file of the new node is set, the
parent nodes are still pointing to the old top, so the backing blocker
is now initialised with the node name rather than the BlockBackend name.

The mirror block job is mainly used for two different scenarios:
Mirroring to an otherwise unused, independent target node, or for active
commit where the target node is part of the backing chain of the source.
Similarly to the commit block job patch, we need to insert a new filter
node to keep the permissions correct during active commit.
Note that one change this implies is that job->blk points to
mirror_top_bs as its root now, and mirror_top_bs (rather than the actual
source node) contains the bs->job pointer. This requires qemu-img commit
to get the job by name now rather than just taking bs->job.

The backup block job doesn't have very complicated requirements: It
needs to read from the source and write to the target, but it's fine
with either side being changed. The only restriction is that we can't
resize the image because the job uses a cached value.
qemu-iotests 055 needs to be changed because it used a target which was
already attached to a virtio-blk device. The permission system correctly
forbids this (virtio-blk can't accept another writer with its default
share-rw=off).

The way that attaching bs->file worked was a bit unusual in that it was
the only child that would be attached to a node which is not opened yet.
Because of this, the block layer couldn't know yet which permissions the
driver would eventually need.
This patch moves the point where bs->file is attached to the beginning
of the individual .bdrv_open() implementations, so drivers already know
what they are going to do with the child. This is also more consistent
with how driver-specific children work.
For a moment, bdrv_open() gets its own BdrvChild to perform image
probing, but instead of directly assigning this BdrvChild to the BDS, it
becomes a temporary one and the node name is passed as an option to the
drivers, so that they can simply use bdrv_open_child() to create another
reference for their own use.
This duplicated child for (the not opened yet) bs is not the final
state, a follow-up patch will change the image probing code to use a
BlockBackend, which is completely independent of bs.

Currently all docker builds are done by exporting a tarball to the
docker container and running the build as the containers root user.
Other use cases are possible however and it is possible to map a part
of users file-system to the container. This is useful for example for
doing cross-builds of arbitrary source trees. For this to work
smoothly the container needs to have a user created that maps cleanly
to the host system.
This adds a -u option to the docker script so that:
DEB_ARCH=armhf DEB_TYPE=stable ./tests/docker/docker.py build \
-u --include-executable=arm-linux-user/qemu-arm \
debian:armhf ./tests/docker/dockerfiles/debian-bootstrap.docker
Will build a container that can then be run like:
docker run --rm -it -v /home/alex/lsrc/qemu/risu.git/:/src \
--user=alex:alex -w /src/ debian:armhf \
sh -c "make clean && ./configure -s && make"

Change the qemu_strtosz() & friends to return -EINVAL when @endptr is

Matches how qemu_strtol() & friends work.
Only test_qemu_strtosz_simple() passes a null @endptr. No functional
change there, because its conversion consumes the string.
Simplify callers that use @endptr only to fail when it doesn't point

The PC machines (pc-q35-* pc-i440fx-* pc-* isapc xenfv) automatically
create lsi53c895a SCSI HBAs and SCSI devices to honor -drive if=scsi.
For giggles, try -drive if=scsi,bus=25,media=cdrom --- this makes QEMU
create 25 of them.
lsi53c895a is thoroughly obsolete (PCI Ultra2 SCSI, ca. 2000), and
currently has no maintainer in QEMU. megasas is a better choice,
except with old OSes that lack drivers. virtio-scsi is a much better
choice when you have a driver, but only (newish) Linux comes with one
in the box. There is no good default that works for all guests.
Encourage users to pick a non-obsolete SCSI HBA that works for them by
deprecating -drive if=scsi.

Add two implementations of the same benchmark as the previous patch,
but using pthreads. One uses a normal QemuMutex, the other is Linux
only and implements a fair mutex based on MCS locks and futexes.
This shows that the slower performance of the 5-thread case is due to
the fairness of CoMutex, rather than to coroutines. If fairness does
not matter, as is the case with two threads, CoMutex can actually be
faster than pthreads.

aio_co_wake provides the infrastructure to start a coroutine on a "home"
AioContext. It will be used by CoMutex and CoQueue, so that coroutines
don't jump from one context to another when they go to sleep on a
mutex or waitqueue. However, it can also be used as a more efficient
alternative to one-shot bottom halves, and saves the effort of tracking
which AioContext a coroutine is running on.
aio_co_schedule is the part of aio_co_wake that starts a coroutine
on a remove AioContext, but it is also useful to implement e.g.
bdrv_set_aio_context callbacks.
The implementation of aio_co_schedule is based on a lock-free
multiple-producer, single-consumer queue. The multiple producers use
cmpxchg to add to a LIFO stack. The consumer (a per-AioContext bottom
half) grabs all items added so far, inverts the list to make it FIFO,
and goes through it one item at a time until it's empty. The data
structure was inspired by OSv, which uses it in the very code we'll
"port" to QEMU for the thread-safe CoMutex.
Most of the new code is really tests.

AioContext is fairly self contained, the only dependency is QEMUTimer but
that in turn doesn't need anything else. So move them out of block-obj-y
to avoid introducing a dependency from io/ to block-obj-y.
main-loop and its dependency iohandler also need to be moved, because
later in this series io/ will call iohandler_get_aio_context.

Peter Maydell recently ran into time-out problems with the
prom-env test on a rather slow ARM board. To tackle this issue,
we can speed up the test by running QEMU with "-nodefaults" for
the pseries machine, so that SLOF has less devices to scan during
boot, and by using the "nvramrc" environment variable instead of
"boot-command", since this variable is evaluated earlier in the
boot process.
And to be really sure that we do not face such time out problems
again, let's also increase the time out value from 100s to 120s
instead.

This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.
This is a long overdue ppc pull request for qemu-2.9. It's been a
long time coming due to some holidays and inconveniently timed
problems with testing. So, there's a lot in here:
* More POWER9 instruction implementations for TCG
* The simpler parts of my CPU compatibility mode cleanup
* This changes behaviour to prefer compatibility modes over
"raW" mode for new machine type versions
* New "40p" machine type which is essentially a modernized and
cleaned up "prep". The intention is that it will replace "prep"
once it has some more testing and polish.
* Add pseries-2.9 machine type
* Implement H_SIGNAL_SYS_RESET hypercall
* Consolidate the two alternate CPU init paths in pseries by
making it always go through CPU core objects to initialize CPU
* A number of bugfixes and cleanups
* Stop the guest timebase when the guest is stopped under KVM.
This makes the guest system clock also stop when paused, which
matches the x86 behaviour.
* Some preliminary cleanups leading towards implementation of the
POWER9 MMU.
There are also some changes not strictly related to ppc code, but for
its benefit:
* Limit the pxi-expander-bridge (PXB) device to x86 guests only
(it's essentially a hack to work around historical x86
limitations)
* Some additions to the 128-bit math in host_utils, necessary for
some of the new instructions.
* Revise a number of qtests and enable them for ppc

This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.
This is a long overdue ppc pull request for qemu-2.9. It's been a
long time coming due to some holidays and inconveniently timed
problems with testing. So, there's a lot in here:
* More POWER9 instruction implementations for TCG
* The simpler parts of my CPU compatibility mode cleanup
* This changes behaviour to prefer compatibility modes over
"raW" mode for new machine type versions
* New "40p" machine type which is essentially a modernized and
cleaned up "prep". The intention is that it will replace "prep"
once it has some more testing and polish.
* Add pseries-2.9 machine type
* Implement H_SIGNAL_SYS_RESET hypercall
* Consolidate the two alternate CPU init paths in pseries by
making it always go through CPU core objects to initialize CPU
* A number of bugfixes and cleanups
* Stop the guest timebase when the guest is stopped under KVM.
This makes the guest system clock also stop when paused, which
matches the x86 behaviour.
* Some preliminary cleanups leading towards implementation of the
POWER9 MMU.
There are also some changes not strictly related to ppc code, but for
its benefit:
* Limit the pxi-expander-bridge (PXB) device to x86 guests only
(it's essentially a hack to work around historical x86
limitations)
* Some additions to the 128-bit math in host_utils, necessary for
some of the new instructions.
* Revise a number of qtests and enable them for ppc

Those could probably be squashed with earlier patches, however I
couldn't easily identify them, test them or check if there are still
necessary on various platforms.

This will help to split char.c in several units without having to
reference them all everywhere. This is useful in particular for tests.

Introduce rules in the top level Makefile that are able to generate
trace.[ch] files in every subdirectory which has a trace-events file.
The top level directory is handled specially, so instead of creating
trace.h, it creates trace-root.h. This allows sub-directories to
include the top level trace-root.h file, without ambiguity wrt to
the trace.g file in the current sub-dir.

Implements 128-bit left shift and right shift as well as their
testcases. By design, shift silently mods by 128, so the caller is
responsible to assert the shift range if necessary.
Left shift sets the overflow flag if any non-zero digit is shifted out.
Examples:
ulshift(&low, &high, 250, &overflow);
equivalent: n << 122
urshift(&low, &high, -2);
equivalent: n << 126
