base-files: uci-defaults-new, config_generate: refactor code and drop old vlans
Remove support for now unused ucidef_add_switch_vlan(), move port->vlan and vlan->interfaces conversion to uci-defaults-new.sh and massively simplify config_generate. This change prepares the following upcoming steps: * Eliminate use of ucidef_set_interface_lan_wan() for switch only devices * Merge ucidef_add_switch() with ucidef_add_switch_ports() Signed-off-by: Jo-Philipp Wich <jow@openwrt.org> SVN-Revision: 47719
