[LEDE-DEV] [PATCH] LuaSrcDiet call define for lua code Minifying

[Jan-Tarek Butt]

Hi,

This patch makes able to minify lua code sequential inside directories.
Here is an example how do can call it in package Makefiles:

Just call the following command inside the package
compile define.
$(call LuaSrcDiet,./luasrc,$(PKG_BUILD_DIR)/luadest/)

luasrc can have subdirectorys there will also created inside luadest
including its minifyed files.

As an example how good it will woke. I minifyed the Nordwest Freifunk
hoodselector[0]. This lua file have currently around 680 lines and a size
of 22042 Bytes after minifying it has just 9480 Bytes.

Here is a table of the minifying process:
