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).

By default, don't allow another writer for block devices that are
attached to a guest device. For the cases where this setup is intended
(e.g. using a cluster filesystem on the disk), the new option can be
used to allow it.
This change affects only devices using DEFINE_BLOCK_PROPERTIES().
Devices directly using DEFINE_PROP_DRIVE() still accept writers
unconditionally.

We want every user to be specific about the permissions it needs, so
we'll pass the initial permissions as parameters to blk_new(). A user
only needs to call blk_set_perm() if it wants to change the permissions
after the fact.
The permissions are stored in the BlockBackend and applied whenever a
BlockDriverState should be attached in blk_insert_bs().
This does not include actually choosing the right set of permissions
everywhere yet. Instead, the usual FIXME comment is added to each place
and will be addressed in individual patches.

This adds an s390 cross build target to our library of docker setups.
There is an issue with the xfslibs-dev:s390x package having a clash so
we do a || apt-get -f install to fixup the rest of the dependencies.
This doesn't build on the debian.docker file as we are using the
multilib compiler which is only available in stretch (the current

blk_insert_bs() and block job related functions will soon require an
opened block node (permission calculations will involve the block
driver), so let our tests be consistent with the real users in this
respect.

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.
