a1417d5305 qemu: Convert from shorthand to longer throttling names
We're about to add 6 new options and it appears (from testing) one cannot
utilize both the shorthand (alias) and (much) longer names for the arguments.
So modify the command builder to use the longer name and of course alter the
test output .args to have the similarly innocuous long name.

Also utilize a macro to build that name makes it so much more visually
appealing and saves a few characters or potential cut-n-paste issues.

a89f05ba8d qemu: Shorten per-domain directory names
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.

d7db33bfe9 qemu: Specify format= iff disk source is not empty
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.

f81e0d480e qemu: assume -drive format is always available
As of QEMU 0.10.0 the -drive format= parameter was added,
so the QEMU driver can assume it is always available.

468273a69c qemu: assume -drive cache always uses v2 option names
As of QEMU 0.10.0, the -drive cache option stopped using
the on/off value names, so the QEMU driver can assume
use of the new value names.

8afd34f2d8 tests: redo test argv file line wrapping
Back in

  commit bd6c46fa0c
  Author: Juerg Haefliger <juerg.haefliger@hp.com>
  Date:   Mon Jan 31 06:42:57 2011 -0500

    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.
