[package] base-files: implement a generic mechanism to map per-interface sysctls to uci.
- option ipv4_xyz is mapped to /proc/sys/net/ipv4/{conf,neigh}/xyz - option ipv6_xyz is mapped to /proc/sys/net/ipv6/{conf,neigh}/xyz This allows e.g. "option ipv6_proxy_ndp 1" to enable NDP proxying on wan. Fixes ticket #8699. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@27653 3c298f89-4303-0410-b956-a3cf2f4a3e73
