Limit and optimize digiline_send (#379)
* Close vulnerability and optimize digiline_send `digiline_send` as it previously existed was vulnerable to a time-of-check-to-time-of-use vulnerability in which a table could be sent, size-checked, and then modified after the send but before delivery. This would allow larger tables to be sent. It was also slow because it called `minetest.serialize`. Fix both of these by implementing custom message cleanup logic which simultaneously computes the message’s cost. * Clean up interaction with Digilines Use `minetest.global_exists` to avoid an undefined global variable warning when operating a Luacontroller with Digilines not available. Use the new `digilines` table in preference to the old `digiline` table. * Copy received messages When a Digiline message is received at a Luacontroller, copy it so that local modifications made by the Luacontroller code will not modify copies of the table that are being passed to other nodes on the Digiline network.
