This function can be called over a domain definition that has no
video configured. The
tests/qemuxml2argvdata/qemuxml2argv-minimal.xml file could serve

segmentation fault in case there's none video configured.

Currently the file based character devices let QEMU write
directly to a file on disk. This allows a malicious QEMU
to inflict a denial of service by consuming all free space.

Switch QEMU to use a pipe to virtlogd, which will enforce
file rollover.

If use of virtlogd is enabled, then use it for backing the
character device log files too. This avoids the possibility
of a guest denial of service by writing too much data to
the log file.

The functions for handling FD passing when building command line
arguments need to be used by many different bits of code, so need
to be at the start of the source file

This attribute is used to extend secondary PCI bar and expose it to the
guest as 64bit memory.  It works like this: attribute vram is there to
set size of secondary PCI bar and guest sees it as 32bit memory,
attribute vram64 can extend this secondary PCI bar.  If both attributes
are used, guest sees two memory bars, both address the same memory, with
the difference that the 32bit bar can address only the first part of the
whole memory.

Per-domain directories were introduced in order to be able to
completely separate security labels for each domain (commit
f1f68ca3).  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.

There's this check when building command line that whenever
domain has no graphics card configured we put -nographics onto
qemu command line. The check is 'if (!def->graphics)'. This
makes coverity think that def->graphics can be NULL, which is
true. But later in the code every access to def->graphics is
guarded by check for def->ngraphics, so no crash occurs. But this
is something that coverity fails to deduct.
In order to shut coverity up lets change the condition to
'if (!def->ngraphics)'.
