paramat 5e4d6468a3 Builtin/../falling.lua: Avoid crash when object pos over limit
If the object pos is over limit, 'add entity' will not add an entity,
causing 'obj' to be nil.

est31 afc48c802a Introduce builtin_shared and use it to fix #4778
Fixes #4778 which was about the error:

ServerError: Lua: Runtime error from mod '' in callback item_OnPlace():
/usr/local/share/minetest/builtin/game/item.lua:278: attempt to call global 'check_attached_node' (a nil value)

The issue was a regression of commit 649448a2a9

"Rename nodeupdate and nodeupdate_single and make them part of the official API"

est31 649448a2a9 Rename nodeupdate and nodeupdate_single and make them part of the official API
Now, the renamed forms of nodeupdate and nodeupdate_single are part of the official API.

As nodeupdate has been used by Minetest Game and in mods despite of not
being part of the official API, we ease the transition by still supporting
it for the 0.4.15 release. After the release, the two functions can be removed.

The removal will not violate the stability promise, as that promise only
includes the official and documented API.

Also, make some formerly global functions local. They most likely haven't
been used by mods, therefore they won't get stubs with deprecation warnings,
hard erroring directly.

paramat 3c5da70d7c Builtin/../falling: Fix bugs caused by 'ignore' nodes
Original commit by t4im, rebased and developed by paramat.
Fix CONTENT_IGNORE being replaced by falling nodes or causing large
areas of sand to collapse into itself.
Format some conditional code for clarity.
Add and clarify some comments.

paramat 89dbc0a25d Builtin/falling: Add fallback vector in case of nil 'wallmounted to dir'
The fallback vector is in case 'wallmounted to dir' is nil due
to voxelmanip placing a wallmounted node without resetting a
pre-existing param2 value that is out-of-range for wallmounted.
The fallback vector corresponds to param2 = 0.

Auke Kok 855a305057 falling: walk 4 additional diagonally down directions.
This seems very little cost and matches the old behavior more
closely. This will cause some more falling nodes to get added
to falling clusters. With the efficiency of the algorithm, this
really doesn't do much damage.

Auke Kok d7908ee494 Convert nodeupdate to non-recursive
This took me a while to figure out. We no longer visit all 9 block
around and with the touched node, but instead visit adjacent plus
self. We then walk -non- recursively through all neigbors and if
they cause a nodeupdate, we just keep walking until it ends. On
the way back we prune the tail.

I've tested this with 8000+ sand nodes. Video result is here:

Took ~ 10 seconds to process and return to normal.

Rui c3f6cdcd54 Falling: Set acceleration on step again
Commit

65c09a96f4 "Set acceleration only once in falling node"

has made the acceleration being set only once.
But this has introduced a regression.

Fix #3884.
