Fixes: #3913#3915
~~You can reproduce the crash by placing a fish bucket on top snow above an unknown node.
I also noticed that the code always uses pointed_thing.above so I fixed that and also added a function to mcl_utils to figure out where a node should be placed (either above or below). Looks like the rest of the code could also use improvement but at least it does not crash now.~~
Cora fixed a bunch of related crashes in Mineclona so I am replacing my commit and cherry picking all her commits here.
https://codeberg.org/mineclonia/mineclonia/pulls/549
Here is the list of fixes from that PR:
- Crash when placing snow layer on unknown nodes
- Crash when snow layers on unknown nodes are flooded
- Crash when placing fishbucket on snow on top of unknown nodes
- Crash when placing chorus flower and stem on unknown
- Crash when placing mob spawners on unknown
- The fishbucket on place to actually replace buildable_to

This pull request renames buckets so that they use the `mcl_` naming convention.
I originally was going to do some renaming on a bigger scope, but decided against it for now.

The function on_place_bucket defined a couple of variables that were
used only once or in a redundant check. After removal of the redundant
check in a previous commit, all use-once variables can now be substituted
with their assignment expressions.
The function on_place_bucket contains the following logic:
if not a and not b then return x end
if a then
foo(a)
elseif b then
foo(b)
else
return x
end
The "if not a and not b then .." is removed because the case is handled
by the else case later on. This will allow some further simplifications.
Instead of directly accessing the group table in node definitions, use
the proper minetest.get_item_group accessor to test for "cauldron"
group.
Also adds local alias get_item_group for the global minetest call.
