[libvirt] [PATCH] qemu: Adding 'downscript' feature for QEMU network interfaces.

Mon May 1 04:03:38 UTC 2017
This commit adds the support for 'downscript' feature:
- For QEMU command line with the option:
'-net downscript=/etc/qemu-ifdown,...'.
- For Domains with a network interface description:
'<interface type='ethernet'>
...
<downscript path='/etc/qemu-ifdown'/>
...
</interface>'
The options 'script' and 'downscript' accept the argument 'no' to disable
the script executions. The way that the code was implemented, the XML file
accepts '<[down]script path='no'>' to solve this problem.
This commit updates the tests too.
