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)
This patch cleans up building the "-boot" parameter and while on that
fixes one inconsistency by modifying these things:
- I completed the unfinished virDomainBootMenu enum by specifying
LAST, declaring it and also declaring the TypeFromString and
TypeToString parameters.
- Previously mentioned TypeFromString and TypeToString are used when
parsing the XML.
- Last, but not least, visible change is that the "-boot" parameter
is built and parsed properly:
- The "order=" prefix is used only when additional parameters are
used (menu, etc.).
- It's rewritten in a way that other parameters can be added
easily in the future (used in following patch).
- The "order=" parameter is properly parsed regardless to where it
is placed in the string (e.g. "menu=on,order=nc").
- The "menu=" parameter (and others in the future) are created
when they should be (i.e. even when bootindex is supported and
used, but not when bootloader is selected).
Prefer bootindex=N option for -device over the old way -boot ORDER
possibly accompanied with boot=on option for -drive. This gives us full
control over which device will actually be used for booting guest OS.
Moreover, if qemu doesn't support boot=on, this is the only way to boot
of certain disks in some configurations (such as virtio disks when used
together IDE disks) without transforming domain XML to use per device
boot elements.
