base-files: depend on jsonfilter and rewrite network.sh to use it
Switches /lib/functions/network.sh from jshn based json parsing to jsonfilter expression while keeping the existing api. Expensive methods like "network_find_wan" are up to 20x faster now. Signed-off-by: Jo-Philipp Wich <jow@openwrt.org> SVN-Revision: 41281
