Libvirt provides full path to the backing file since commit
fec8f9c49a. This made qemu create the backend object but did not
delete it. This was fixed for unplug case in 4d83a6722f but not in case
of failure to hotplug the frontend. We'd leave the files behind which
would make memory unusable in case of hugepages.

Having to repeat "./job[1]/" XPath prefix for every single element or
attribute we want to parse is suboptimal. And even more so once we
further extract code from qemuDomainObjPrivateXMLParseJob into separate
functions.

The daemonStreamHandleWriteData() function is called whenever
server side of stream is able to receive some data. Nevertheless,
it calls virStreamSend() (to pass data down to virFDStream) and
depending on its return value it may abort the stream. However,
the functions it called when doing so are public APIs and as such
reset any error set previously. Therefore, if there was any error
in writing data to stream (i.e. repored in virStreamSend) it is
reset before virNetServerProgramSendReplyError() can get to it.

Some fields reported by dmidecode have plenty of useless spaces
(in fact some have nothing but spaces). To deal with this we have
introduced virSkipSpacesBackwards() and use it in
virSysinfoParseX86Processor() and virSysinfoParseX86Memory().
However, other functions (e.g. virSysinfoParseX86Chassis()) don't
use it at all and thus we are reporting nonsense:
<sysinfo type='smbios'>
<chassis>
<entry name='manufacturer'>FUJITSU</entry>
<entry name='version'> </entry>
<entry name='serial'> </entry>
<entry name='asset'> </entry>
<entry name='sku'>Default string</entry>
</chassis>

Commit 596fc3e389 introduced the ability to detect xenstore
using pkg-config for systems with Xen 4.9, but accidentally broke

We read from the agent until seeing a \r\n pair to indicate a completed
reply or event. To avoid memory denial-of-service though, we must have a
size limit on amount of data we buffer. 10 MB is large enough that it
ought to cope with normal agent replies, and small enough that we're not
consuming unreasonable mem.
This is identical to the flaw we had reading from the QEMU monitor
as CVE-2018-5748, so rather embarrassing that we forgot to fix
the agent code at the same time.
