c12ce2b4dd Prevent move_and_slide() to generate an error.
When moving KinematicBody2D from one scene to another and not freeing
the old scene, the first call to move_and_slide() in the new scene will
generate an error because KinematicBody2D keeps internaly a
RID on_floor_body of a body resource in the old scene which no more has
a space assigned.

To fix this, on_floor_body is set to empty RID in response to
NOTIFICATION_ENTER_TREE notification of KinematicBody2D and
KinematicBody. Also all other data related to move_and_slide() is reset:
floor, ceiling, wall flags, colliders vector, floor_velocity.

This fixes #31416.

6dd65c0d67 KinematicBody performance and quality improvements
With this change finally one can use compound collisions (like those created
by Gridmaps) without serious performance issues. The previous KinematicBody
code for Bullet was practically doing a whole bunch of unnecessary
calculations. Gridmaps with fairly large octant sizes (in my case 32) can get
up to 10000x speedup with this change (literally!). I expect the FPS demo to
get a fair speedup as well.

List of fixes and improvements:

- Fixed a general bug in move_and_slide that affects both GodotPhysics and
  Bullet, where ray shapes would be ignored unless the stop_on_slope parameter
  is disabled. Not sure where that came from, but looking at the 2D physics
  code it was obvious there's a difference.
- Enabled the dynamic AABB tree that Bullet uses to allow broadphase collision
  tests against individual shapes of compound shapes. This is crucial to get
  good performance with Gridmaps and in general improves the performance
  whenever a KinematicBody collides with compound collision shapes.
- Added code to the broadphase collision detection code used by the Bullet
  module for KinematicBodies to also do broadphase on the sub-shapes of
  compound collision shapes. This is possible thanks to the dynamic AABB
  tree that was previously disabled and it's the change that provides the
  biggest performance boost.
- Now broadphase test is only done once per KinematicBody in Bullet instead of
  once per each of its shapes which was completely unnecessary.
- Fixed the way how the ray separation results are populated in Bullet which
  was completely broken previously, overwriting previous results and similar
  non-sense.
- Fixed ray shapes for good now. Previously the margin set in the editor was
  not respected at all, and the KinematicBody code for ray separation was
  complete bogus, thus all previous attempts to fix it were mislead.
- Fixed an obvious bug also in GodotPhysics where an out-of-bounds index was
  used in the ray result array.

There are a whole set of other problems with the KinematicBody code of Bullet
which cost performance and may cause unexpected behavior, but those are not
addressed in this change (need to keep it "simple").

Not sure whether this fixes any outstanding Github issues but I wouldn't be
surprised.

6ec4da2e3b Fix inconsistency in KinematicBody
- moved new infinite_inertia argument of move_and_slide and
move_and_slide_with_snap in KinematicBody and KinematicBody2D to the
end if not already there. This makes the order of arguments consistent
and should keep projects from 3.0 compatible as this argument did not
exist in 3.0. Docs updated accordingly.
- renamed max_bounces to max_slides for consistency. Docs updated
accordingly.
- the argument infinite_inertia in test_move is now optional, as it is
in every other movement related method. This closes #22829.

e2df5d661d Ported/fixed move_and_slide to KinematicBody (3D+floor/ceiling args)
This version of the commit has the on_ceiling/on_wall fix without any
 explaination of that code, since apparently it wasn't complicated enough.

As for the notes at the top of the function, they're still there.

move_and_slide is rather useful for character-controllers, etc.
It reduces the amount of boilerplate code.
Not having move_and_slide makes the APIs somewhat inconsistent.

(It might be nice to figure out a way to share the code between the two
move_and_slide implementations, but that's for someone who knows what
the policy is on shared code like that.)

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

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!

f33d9dab5b Fix can_move_to and rename it for more clarity
Fixes #2416.
The KinematicBody::can_move_to function was likely designed for two behaviours:
 - discrete: check if the body can "teleport" to the destination
 - continuous: check if the direct path to the destination is valid
The continuous behaviour was however not implemented, and the discrete behaviour was broken too due to a wrong call to intersect_shape.

The discrete behaviour has thus been fixed and the function renamed to can_teleport_to for more clarity.

abbea4d945 UDP Fixes
-=-=-=-=-

Curse the day I decided to port UDP code, as it ended up
being two nights of work.  At least It's done now (I hope).

-Fixed UDP Support, API seems stable
-Added UDP Chat demo (chat that can lose your packets, heh)
-Added helpers to areas and bodies to get list of collided bodies and contained bodies.
-Sped up screen/viewport capture code.
-Added code to save an image as PNG
-Small fix so scripts register their singletons after modules did.
