The internal batman-adv compat version numbers are just confusing for
the user. Instead, let's just name things "batman-adv" when refering to
compatibility version 15 and "batman-adv-legacy" when refering to
compatibility version 14.

batman-adv-legacy now uses its own namespaces. And whether to use v14 or
v15 is determined by the routing algorithm specified in the site
configuration. Which means both the batman-adv and batman-adv-legacy
kernel modules as well as the according glue code provided by
gluon-mesh-batman-adv-14 and gluon-mesh-batman-adv-15 can be installed
at the same time.
