qemu-config: qemu_read_config_file() reads the normal config file
Introduce a new function qemu_read_config_file which reads the VM configuration from a config file. Unlike qemu_config_parse it doesn't take a open file but a filename and reduces code duplication as a side effect. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
