[libvirt] [RFC] qemu: support for QEMU bridge helper

[Corey Bryant <coreyb linux vnet ibm com>]

The QEMU bridge helper allows QEMU to be executed with bridge networking 
support from a non-privileged user.  For more details see:
http://lists.gnu.org/archive/html/qemu-devel/2012-01/msg03562.html

I would like to see if there is interest in adding support to allow 
libvirt to execute guests with "-net bridge" support.

This support would complement another feature we are currently working 
on, which provides per-guest configurable user/group for QEMU processes. 
 This will enable guests to be run from separate non-privileged IDs. 
For more details see:
