* For some unexplained reason, `mcl_burning.storage[player]` can
sometimes be `nil`, causing a crash in `on_leaveplayer()`. This
commit adds a check for that. If a `nil` is encountered, a sane
value is substituted and a warning is set to the log.
* Change carpet from `group:attached_node` to `group:supported_node`,
allowing carpets to be placed on top of torches, water source blocks
and other non-walkable nodes, like in MC.
* Add support for `group:supported_node` to CORE/mcl_attached.
Supported nodes are nodes that can be placed on any node that does not
have the `drawtype = "airlike"` attribute.
* Copy the `drop_attached_node()` function from minetest/builtin, so
that the override function provides the same behavior when nodes drop.
* Add comments to CORE/mcl_attached and to the functions defined in it.
* Add more local aliases for global minetest.* functions.
* If the original function returns true, it is not necessary anymore
to perform more tests and the override function can simply return true
immediately.
* Remove unused code that was commented out. The code tried to find
fire luaentities in the same spot as the newly created fire luaentity.
It may have been intended to optimize getting set on fire multiple
times, but it makes no sense as it does not discriminate between fire
luaentities attached to the object set on fire and those attached to
other objects. The function that this code was in also has a better
way to prevent adding multiple fire luaentities in the first place.
* In mineclone5 a crash was reported to occur when deserialization of
storage returned nil in on_joinplayer. https://git.minetest.land/

This commit uses a different, but equally effective fix.
* Remove animation_frame from fire entity state, it is now kept in the
storage table of the parent entity.
* Rename animation_timer in fire entity table to _mcl_animation_timer,
in line with mineclone2 policy on adding custom members to minetest
tables.
* Comment out code that does nothing sensible. Scheduled for deletion
at a later time.
* Make carpets walkable. When a carpet is placed on top of a fence or a
wall, the carpet can be jumped upon, allowing to in effect jump over
fences and walls.
The daylight detector code used get_node_light(), which detects both
natural and artificial light. This patch improves the code to use
get_natural_light(), which was introduced with Minetest 5.4.0.
* Check if node has a definition table before attempting to evaluate its
attributes. By application of De Morgan's law, the compound logic
expression can be rewritten so that the existence of the table is
checked before all following attribute references.
* Check if node has a definition table before attempting to evaluate its
attributes.
* Define local variable to cache multiple accesses to `registered_nodes[]`
and improve readability.
* Clarify code flow.
* Check if node has a definition table before attempting to evaluate its
attributes.
* Define local variable to cache multiple accesses to `registered_nodes[]`
and improve readability.
* Mobs redo uses `registered_items[]` where clearly the proper table
accessed should be `registered_nodes[]`. Perhaps this magically
works, but it looks nonsensical. Switch to the use the more
sensible `registered_nodes[]` table.

This solves a problem were nether portal removal would trigger deep
recursion through node callbacks. For large portals this could result
in stack overflow crashes on LuaJIT. The issue is solved by rewriting
the portal removal to avoid recursion and removing the portal in one
operation using minetest.bulk_set_node.
Changes to mcl_burning.set_on_fire():
* Add logic that only updates the burn time, but skips adding fire
entities to objects that are already burning.
* Condense code a little, remove single use variables.
* Add a comment to a questionable piece of code.
* Add comments to the function.
* Add update_hud() function.
* Remove the client channels.
* Unglobalize animation_frames variable.
* Fix bug where player state was not stored on shutdown of singleplayer
game.
* Remove superfluous sanity_check() function, this code could easily be
inlined in its only caller.
The parameters for the flames sprite were incorrect, causing the reverse
side of the sprite to appear as an opaque black rectangle. Use the
correct incantation.
Before this patch, the tga_encoder mod would write corrupted TGA files
on Windows: Bytes that looked like newlines were replaced by a carriage
return and a newline.
During the rewrite in 89e55e9065, a queue system was added to allow
using both VoxelManip-based generation steps, and set_node-based steps,
however some set_node-based steps (underground mushrooms, nether
decorations, and structures) were missed and remained in a VoxelManip
step. The result is that the changes made by the set_node stages were
overwritten after the (now-stale) VoxelManip data was committed later.

The function dynamic_add_media() was changed in incompatible ways in
several minor versions of Minetest, breaking the display of handheld
maps in Minetest 5.5.0. This patch makes handheld maps display there.
The function was blocking with one argument in Minetest 5.3. It was also
blocking in Minetest 5.4, but took an additional argument for a function
to execute once the media had been received. Calling dynamic_add_media()
with a single argument had been deprecated; a function that did nothing
was provided in mcl_maps to satisfy the changed argument requirements.
In Minetest 5.5, dynamic_add_media() was changed to non-blocking. This
introduced a race condition in mcl_maps, where a client often tried to
display a map before it had received the map texture from the server.
Opening an issue on the Minetest issue tracker led to it being closed in
about 20 minutes: <https://github.com/minetest/minetest/issues/11997>
Redstone comparators have two modes, comparison mode & subtraction mode.
Before this patch, the functions to turn comparators on or off attempted
to swap nodes with comparators in the same mode, but failed to determine
the correct replacement node, if the existing node was not a comparator.
When a comparator in an on state (e.g. powered by a filled cauldron) was
flooded, the flooding dropped the comparator and replaced the comparator
node that was to be swapped out with air, which lead to a server crash.
This patch changes the functions that turn comparators on or off so they
only swap existing nodes with comparators in the same mode if the name
of the replacement node can be determined – i.e. if it is not nil.
In commit 55009c257e that added vectors to
mcl_composters, mcl_hoppers was accidentally patched with a unrelated
change, updating it to get_item_group(). This mostly works, but in one
particular case the semantics of the return value differs. Instead of
returning 'nil' it returns '0'. That altered the evaluation of an if
condition, breaking the abm that sucks in items.
This commit fixes the conditional by explicitly comparing '~= 0'.
