Improve Nether Portals (#1315) (as a squash)

Browse source 
Remove Nether portal caches, https://git.minetest.land/MineClone2/MineClone2/issues/1210

Store all exits from Nether portals in quick-access table

Implement proper Nether portal search, using the table, https://git.minetest.land/MineClone2/MineClone2/issues/1055

Store Nether portal exits table in mod storage

Remove exits from table on Nether portal destruction

Align destination area to [map chunks 5x5x5](https://git.minetest.land/MineClone2/MineClone2/wiki/World-structure%3A-positions%2C-boundaries%2C-blocks%2C-chunks%2C-dimensions%2C-barriers-and-the-void) to avoid lots of ```emerge_area()``` calls

Support Nether roof, https://git.minetest.land/MineClone2/MineClone2/issues/1267

Implement better suitable place search, https://git.minetest.land/MineClone2/MineClone2/issues/1126

Implement object queue not to trigger the same search again

Avoid lava lakes, https://git.minetest.land/MineClone2/MineClone2/issues/1126

Add ```/spawnstruct nether_portal``` chat command
