[libvirt] [PATCH 11/25] qemu: Introduce qemuBuildSerialCommandLine

Thu Feb 18 17:50:55 UTC 2016
Add new function to manage adding the serial device options to the
command line removing that task from the mainline qemuBuildCommandLine.
Using const virDomainDef causes collateral damage in other called APIs
which need to make the similar adjustment
