Fix seg fault if popping from empty stack (L-system trees)
See: https://github.com/minetest/minetest/issues/1525 Background Wuzzy2: If you attempt to spawn a L-system tree with minetest.spawn_tree, you can make Minetest crash if it is attempted to pop an empty stack. ShadowNinja: This shouldn't cause a segmentation fault, but it should throw a Lua error Commit Description This commit throws a Lua error instead of causing a segmentation fault. The server will still "crash" but will include a Lua backtrace. L-Systems fix randomness Unless a random seed is provided (via Lua treedef) seed the PRNG with a different seed for each tree Resolves: https://github.com/minetest/minetest/issues/1469 Fix l-system crash when treedef random_level not set by Lua
