Revert "Fix issue #2441: crash on respawn, since a conversion std::list to std::vector on Environment.cpp"

This reverts parts of commit 9749d9fe, which breaks node resolver
list clearing

* Also change some std::list to std::vector for ClientMap::renderMap
* Remove disabled code in ClientMap::renderMap, disabled since a long time

Add minetest.get_mapgen_params()
Deprecate minetest.register_on_mapgen_init()

Also set default height_min/height_max to -31000 and 31000,
respectively, for ore and biomes

Biome API: Add shore top and shore filler nodes, underwater node, water top node. Add water top depth and shore height parameters. Remove water dust node

Add 'absolute value' option to noise map functions
Extend persistence modulation to 3D noise
Extend 'eased' option to noise2d_perlin* functions
Some noise.cpp formatting fixups

Add support for notify-on-decoration
Clean up mapgen constructors
Clean up mapgen.cpp code style somewhat
Remove trailing whitespace from some files

Add definable node_stone to biome API, mgv5, mgv7. Reduce and correct depth of mgv7 biomes. l_mapgen.cpp: add '#include mapgen_v5.h' because '#include mapgen_v7' is there. Improve underwater grass hack

Add BiomeManager, OreManager, DecorationManager, and SchematicManager

Split up ModApiMapgen::l_register_decoration()
Define and make use of CONTAINS() and ARRLEN() macros

This also cleans up settings a bit
