Abort when trying to set a not registered node (#7011)
I removed the MapNode constructor which takes a nodename and gives the node's id or CONTENT_IGNORE
The code which used this constructor (two places) now handles the situation of not registered nodes correctly:
* minetest.set_node and similar functions make minetest crash when a not registered node is passed
* reverting a node with rollback aborts if the node is not registered

Optimize string handling in path search (#8098)
Use "append" method to construct the various game paths
instead of wasteful string concatenation. Additionally, use a
temporary to extract and reuse a result of a few common
subexpressions to further reduce the overhead.

Optimize interaction distance checker (#8193)
The "what" parameter is being passed by value, most likely by
accident as the type is "const std::string". Convert it to a
reference by adding the missing "&".
The sound specified in `node_definition.sounds.fall` is used.
When a falling node is spawned at a position or an attached node drops, the sound is played at this position.
* Allow adjusting the log color with an environment variable
If --color is not passed to minetest, is used to decide on the log colorization.
Minetest settings can not be used instead of an environment variable because logs may appear before loading them.
Replace for loop with call to standard library function (#8194)
This loop makes multiple passes over m_stack (type std::list) in order to remove all elements with a specified value. Replacing the loop with a call to std::list::remove does the same job, but in only one pass.

Add referer to remote media requests. (#8135)
This sends the following header to a remote media server:
Referer: minetest://<server_name>:port
This was verified with CTF and the Minetest Public Remove Media
server. If the servername was a plain IPv6 address it will
contain `:` characters and will be encapsulated in `[]` to
be a valid URI.

getS16NoEx() returns true unless syntactical error in conf. (#8304)
The getS16NoEx() handler will return true unless there is a
`[num_emerge_threads]` line in the `minetest.conf` at which
point the excption handler part is reached. Due to the fact that
`defaultsettings.cpp` has a default value set for this setting,
that never will happen.
Because of this, the code will never check the number of threads on
the system, and keep `nthreads = 0`. If that happens, the value is
changed to `1` and only 1 emerge thread will be used.
The default should be set to `1` instead, due to the potential unsafe
consequences for the standard sqlite map files, but that should be a
separate commit that also adds documentation for that setting. This
commit focuses on removing this `hiding` bug instead.

Use true pitch/yaw/roll rotations without loss of precision by pgimeno (#8019)
Store the rotation in the node as a 4x4 transformation matrix internally (through IDummyTransformationSceneNode), which allows more manipulations without losing precision or having gimbal lock issues.
Network rotation is still transmitted as Eulers, though, not as matrix. But it will stay this way in 5.0.

blitToVManip: Check out-of-bounds using node position not index (#8127)
Previously, when using 'place on vmanip' to add a schematic to a
lua voxelmanip, if part of the schematic was outside the voxelmanip
volume, the outside part would often appear in a strange place
elsewhere inside the voxelmanip instead of being trimmed off.
This was due to the out-of-bounds check checking the index.
A position outside the voxelmanip can have an index that satisfies
'0 <= index <= voxelmanip volume', causing the node to be placed
at a strange position inside the voxelmanip.
Use 'vm->m_area.contains(pos)' instead.
Move index calculation to later in the code to optimise.

Fix randomly rejected form field submits (#8091)
If a formspec is submitted from a form fields handling
callback of another form (or "formspec shown from another
formspec"), the fields submitted for it can get
rejected by the form exploit mitigation subsystem with a
message like "'zorman2000' submitted formspec
('formspec_error:form2') but server hasn't sent formspec to
client, possible exploitation attempt" being sent to logs.
This was already reported as #7374 and a change was made
that fixed the simple testcase included with that bug
report but the bug still kept lurking around and popping
out in more complicated scenarios like the advtrains TSS
route programming UI.
Deep investigation of the problem revealed that this
sequence of events is entirely possible and leads to the
bug:
What happens inside the code is that when the server in
step 4 sends form2, the registry of opened forms is
updated to reflect the fact that form2 is now the valid
form for the client to submit. Then when in step 5 client
says "form1 was closed", the exploit mitigation subsystem
code deletes the registry entry for the client without
bothering to check whether the form client says was
closed just now is indeed the form that is recorded in
that entry as the valid form. Then later, in step 7 the
client tries to submit its valid form fields, these will
be rejected because the entry is missing.
It turns out the procedure where the broken code resides
already gets the form name so a simple "if" around the
offending piece of code fixes the whole thing. And
advtrains TSS agrees with that.
