Staging: batman-adv: moving vis output formats out of the kernel

The batman-adv kernel module is able to output visualization data using the
dot draw or JSON format. This patch transforms the output into a generic
format (called vis raw). User space tool may convert the raw data to support
a variety of formats without the need of modifying the kernel module.
