Builtin: Redo serialize.lua (#11427)
Features:

* Support for arbitrary references, including self-referencing
* Short output, references "long" strings as a bonus
* Around the same speed, potentially slower if long, short keys are present
* Properly works with NaN and inf

Add relative numbers for commands by prepending ~ (#9588)
* Add relative numbers for commands by prepending ~

* Some builtin code cleanup

* Disallow nan and inf in minetest.string_to_area

* Remove unused local variable teleportee (makes Luacheck happy)

* Clean up core.string_to_pos

* Make area parsing less permissive

* Rewrite tests as busted tests

* /time: Fix negative minutes not working

Add vector.to_string and vector.from_string (#10323)
Writing vectors as strings is very common and should belong to `vector.*`. `minetest.pos_to_string` is also too long to write, implies that one should only use it for positions and leaves no spaces after the commas.

Some vector functions useful for working with rotations (#9572)
* added vector.rotate

* added vector.forward_from_rotation and vector.up_from_rotation

* added vector.forward_up_to_rotatiton

* fixed some bugs and formatting with vector functions

* shortened name of some new vector functions and added documentation

* made vector.rotate not require a unit vector as axis

* fixed crash with vector.forward_up_to_rot

* renamed new vector functions, made vector.rotate apply a rotation matrix, old vector.rotate is now called vector.rotate_around_axis

* documented vector function changes

* removed some whitespace to appease luacheck

* implemented and fixed optimization of vector.rotate_around_axis by SmallJoker

* added some unit tests for rotation vector functions

* clarified that rotation vectors are in radians and according to the left hand rule

* hopefully appeased luacheck

* renamed rotation_to_horizontal to forward_at_rotation, rotation_to_vertical to up_at_rotation

* handled cases where sin or cos are 0 in rotation vector functions

* added more comments

* clarified documentation of rotation vector functions

* added more unit tests

* changed way in which vector.rotate_around_axis is adjusted for left handed coordinate systems

* made vector.rotate_around_axis actually left handed

* unrolled matrix multiplication

* removed vector.forward_at_rotation and vector.up_at_rotation

* prettified vector.rotate_around_axis, made previous commits not break anything

* removed references to removed vector.forward_at_rotation and vector.up_at_rotation

* removed documentation of removed vector functions

* clarified documentation and fixed styling of rotation vector functions

* restyled comments minorly

* spelling fixes and some hopefully better comments

* allowed 'up' to be missing from vector.directions_to_rotation and removed requirement for unit vectors as arguments

* made vector.rotate_around_axis() right handed again for consistency

* documented previous changes

* made matrix multiplication actually multiply

* renamed vector.directions_to_rotation() to vector.dir_to_rotation()

* optimized a distance comparison

* Fixed potential false positive in unit tests.

minetest.serialize: Reversible number serialization (#9722)
* minetest.serialize: Reversible number to string conversion

The %a format is not supported in Lua 5.1.
This commit also adds two tests for number serialization.
