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 ~
* 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

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.
This PR is the second attempt to translate builtin.
Server-sent translation files can be added to `builtin/locale/`, whereas client-side translations depend on gettext.
* 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 to string conversion
The %a format is not supported in Lua 5.1.
This commit also adds two tests for number serialization.
All on_* hooks that return an itemstack are NOT guaranteed to
modify and return the original stack. We cannot count on the
behavior of the existing builtin definitions not to be overridden
by game/mod logic.
Calling string.split(":A:B:C:D", ":") returns an empty array.
This is due to first empty string not making repeat loop decreasing max_split which has a 0 value when reaching until.
Changing max_splits default value from -1 to -2 fixes that issue.
