This commit contains the following: * Update binary to version 1.6.1 * Update README URLs in the Makefile to link OpenWrt-specific info * Separate the binary, the init script and netifd script into 3 packages: nebula, nebula-service and nebula-proto accordingly * implement yml parser for init script to fetch variables from it * add the netifd script for nebula protocol * update test file to address all built packages * make the PKG_VERSION variable of init/proto scripts readonly Signed-off-by: Stan Grishin <stangri@melmac.ca>
