7b3790d2cc Add option to consider disable points
Previously, disabled points will not be considered when performing
get_closest_point. This commit changes that by introducing an additional
flag for this behavior. Related issue: #31814

277b24dfb7 Make core/ includes absolute, remove subfolders from include path
This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.

40562a67c8 Changed A* exit condition, added 2 tests for it
A* now exits when next node from open set with least cost happens to be end_point,
not when node with least cost has end_point as a neigbour.

Added two tests for astar:
* ABC tests case where start and end node are
neigbours
* ABCX tests case with intermediate nodes

9b60bb2c7c Change the neighbours vector to a set in AStar
This fixes an issue where one could not disconnect two points that were connected more than once.

Using `misc/scripts/fix_headers.py` on all Godot files.
Some missing header guards were added, and the header inclusion order
was fixed in the Bullet module.

Rename user facing methods and variables as well as the corresponding
C++ methods according to the folloming changes:

* pos -> position
* rot -> rotation
* loc -> location

C++ variables are left as is.

e4eb093c62 Avoid overestimating the cost in AStar heuristics.
This is a necessary condition for finding optimal solutions.
This is achieved by simply requiring/ensuring that no weights are smaller than 1.

Fixes #8584.

5dbf1809c6 A Whole New World (clang-format edition)
I can show you the code
Pretty, with proper whitespace
Tell me, coder, now when did
You last write readable code?

I can open your eyes
Make you see your bad indent
Force you to respect the style
The core devs agreed upon

A whole new world
A new fantastic code format
A de facto standard
With some sugar
Enforced with clang-format

A whole new world
A dazzling style we all dreamed of
And when we read it through
It's crystal clear
That now we're in a whole new world of code

6f4f9aa6de Overloaded basic math funcs (double and float variants). Use real_t rather than float or double in generic functions (core/math) whenever possible.
Also inlined some more math functions.

3890256fc5 Style: Cleanups, added headers, renamed files
Made sure files in core/ and tools/ have a proper Godot license header
when written by us. Also renamed aabb.{cpp,h} and object_type_db.{cpp,h}
to rect3.{cpp,h} and class_db.{cpp,h} respectively.

Also added a proper header to core/io/base64.{c,h} after clarifying
the licensing with the original author (public domain).

118eed485e ObjectTypeDB was renamed to ClassDB. Types are meant to be more generic to Variant.
All usages of "type" to refer to classes were renamed to "class"
ClassDB has been exposed to GDScript.
OBJ_TYPE() macro is now GDCLASS()

c7bc44d5ad Welcome in 2017, dear changelog reader!
That year should bring the long-awaited OpenGL ES 3.0 compatible renderer
with state-of-the-art rendering techniques tuned to work as low as middle
end handheld devices - without compromising with the possibilities given
for higher end desktop games of course. Great times ahead for the Godot
community and the gamers that will play our games!

It's pretty fast, use it for games where Navigation does not cut it.
