[PATCH 16/25] qemu: Introduce qemuBuildInputCommandLine

[John Ferlan <jferlan@xxxxxxxxxx>]

Add new function to manage adding the input device options to the
command line removing that task from the mainline qemuBuildCommandLine.

Make qemuBuildUSBInputDevStr static since only this module calls it.

Also the change to use const virDomainDef forces other changes.
