The capabilities used in test cases should match those used
during normal operation for the tests to make any sense.
This results in the generated command line for a few test
cases (most notably non-x86 test cases that were wrongly
assuming they could use -no-acpi) changing.
Per-domain directories were introduced in order to be able to
completely separate security labels for each domain (commit
f1f68ca334). However when the domain
name is long (let's say a ridiculous 110 characters), we cannot
connect to the monitor socket because on length of UNIX socket address
is limited. In order to get around this, let's shorten it in similar
fashion and in order to avoid conflicts, throw in an ID there as well.
Also save that into the status XML and load the old status XMLs
properly (to clean up after older domains). That way we can change it
in the future.
The shortening can be seen in qemuxml2argv tests, for example in the
hugepages-pages2 case.

Just recently, qemu forbade specifying format for sourceless
disks (qemu commit 39c4ae941ed992a3bb5). It kind of makes sense.
If there's no file to open, why specify its format. Anyway, I
have a domain like this:
<disk type='file' device='cdrom'>
<driver name='qemu' type='raw'/>
<target dev='hda' bus='ide'/>
<readonly/>
<address type='drive' controller='0' bus='0' target='0' unit='0'/>
</disk>
and obviously I am unable to start it. Therefore, a fix on our
side is needed too.

As of QEMU 0.10.0 the -drive format= parameter was added,
so the QEMU driver can assume it is always available.

tests: handle backspace-newline pairs in test input files
all the test argv files were line wrapped so that the args
were less than 80 characters.
The way the line wrapping was done turns out to be quite
undesirable, because it often leaves multiple parameters
on the same line. If we later need to add or remove
individual parameters, then it leaves us having to redo
line wrapping.
This commit changes the line wrapping so that every
single "-param value" is one its own new line. If the
"value" is still too long, then we break on ',' or ':'
or ' ' as needed.
This means that when we come to add / remove parameters
from the test files line, the patch diffs will only
ever show a single line added/removed which will greatly
simplify review work.

On my machine, a guest fails to boot if it has a sound card, but not
graphical device/display is configured, because pulseaudio fails to
initialize since it can't access $HOME.
A workaround is removing the audio device, however on ARM boards there
isn't any option to do that, so -nographic always fails.
Set QEMU_AUDIO_DRV=none if no <graphics> are configured. Unfortunately
this has massive test suite fallout.
Add a qemu.conf parameter nographics_allow_host_audio, that if enabled
will pass through QEMU_AUDIO_DRV from sysconfig (similar to
vnc_allow_host_audio)
Long lines are harder to read and harder to diff; in fact, if lines get
too long (> 1000 bytes), it starts causing issues where git send-email
refuses to send patches for the file. I've cleaned up the tests
directory in the past (see commits bd6c46f, 3b750d1), but new long
lines have been introduced in the meantime.
Why 90 instead of 80? Because there were too many tests on the fringe
edge, and I didn't want to edit that many files.
Add a syntax check to prevent future long lines.
* cfg.mk (sc_prohibit_long_lines): New rule.
* tests/qemuxml2argvdata/qemuxml2argv-*.args: Split lines of any
file with content longer than 90 columns.
* tests/storagevolxml2argvdata/*.argv: Likewise.

For any disk controller model which is not "lsilogic", the command
line will be like:
-drive file=/dev/sda,if=none,id=drive-scsi0-0-3-0,format=raw \
-device scsi-disk,bus=scsi0.0,channel=0,scsi-id=3,lun=0,i\
drive=drive-scsi0-0-3-0,id=scsi0-0-3-0
The relationship between the libvirt address attrs and the qdev
properties are (controller model is not "lsilogic"; strings
inside <> represent libvirt adress attrs):
bus=scsi<controller>.0
channel=<bus>
scsi-id=<target>
lun=<unit>
* src/qemu/qemu_command.h: (New param "virDomainDefPtr def"
for function qemuBuildDriveDevStr; new param "virDomainDefPtr
vmdef" for function qemuAssignDeviceDiskAlias. Both for
virDomainDiskFindControllerModel's use).
* src/qemu/qemu_command.c:
- New param "virDomainDefPtr def" for qemuAssignDeviceDiskAliasCustom.
For virDomainDiskFindControllerModel's use, if the disk bus is "scsi"
and the controller model is not "lsilogic", "target" is one part of
the alias name.
- According change on qemuAssignDeviceDiskAlias and qemuBuildDriveDevStr
* src/qemu/qemu_hotplug.c:
- Changes to be consistent with declarations of qemuAssignDeviceDiskAlias
qemuBuildDriveDevStr, and qemuBuildControllerDevStr.
* tests/qemuxml2argvdata/qemuxml2argv-pseries-vio-user-assigned.args,
tests/qemuxml2argvdata/qemuxml2argv-pseries-vio.args: Update the
generated command line.
Add four tests of the XML -> argv handling for the PPC64 pseries machine.
The first is just a basic test of a bare bones machine.
The three others test various aspects of the spapr-vio address handling.
It seems that currently we can't include network devices, doing so leads
to a segfault because the network driverState is not initialised. Working
around that leads us to the problem that the 'default' network doesn't
exist. So for now just leave network devices out.
