0e29f7974b Reduce unnecessary COW on Vector by make writing explicit
This commit makes operator[] on Vector const and adds a write proxy to it.  From
now on writes to Vectors need to happen through the .write proxy. So for
instance:

Vector<int> vec;
vec.push_back(10);
std::cout << vec[0] << std::endl;
vec.write[0] = 20;

Failing to use the .write proxy will cause a compilation error.

In addition COWable datatypes can now embed a CowData pointer to their data.
This means that String, CharString, and VMap no longer use or derive from
Vector.

_ALWAYS_INLINE_ and _FORCE_INLINE_ are now equivalent for debug and non-debug
builds. This is a lot faster for Vector in the editor and while running tests.
The reason why this difference used to exist is because force-inlined methods
used to give a bad debugging experience. After extensive testing with modern
compilers this is no longer the case.

8d5c30ce83 Handle missing arg pointer in get_call_error_text
I had a situation coming from godot-python where the caller of
Variant::get_call_error_text() passed null for `p_argptrs`. In
addition to fixing that in the caller, seems like good practice to
defend against that situation in the callee to prevent a crash.

So this patch just substitutes some semi-useful text for the source
type name and keeps going so the user's actual error gets emitted.

22358babda Implement Linux-style likely()/unlikely() macros
This implement branch prediction macros likely() and unlikely() like in
Linux. When using these macros please ensure that when you use them the
condition in the branch really is very, very likely or unlikely. Think
90+% of the time. Primarily useful for error checking. (And I implement
these macros for all our error checking macros now)

See this article for more information:
https://kernelnewbies.org/FAQ/LikelyUnlikely

There are more places where these macros may make sense in renderer and
physics engine. Placing them will come in another commit down the line.

d05965963d Don't call Variant::reference() unnecessarily
operator= does not need to call reference() if the new value is of the
same type as the old. This saves us zeroing the Variant, This speeds
up reuse of a Variant in a loop by roughly 50%.

f08bc0df7c Construct Variants from Reference properly in GDNative
Previously godot_variant_new_object constructed Variant without
accounting for the fact that the Object can be a Reference, so refcount
was not increased and References were destructed prematurely.

Also, Reference::init_ref did not propagate refcount increment to the
script instance, which led to desync of refcount info on the script
side and Godot side.

cacced7e50 Convert Object::cast_to() to the static version
Currently we rely on some undefined behavior when Object->cast_to() gets
called with a Null pointer. This used to work fine with GCC < 6 but
newer versions of GCC remove all codepaths in which the this pointer is
Null. However, the non-static cast_to() was supposed to be null safe.

This patch makes cast_to() Null safe and removes the now redundant Null
checks where they existed.

It is explained in this article: https://www.viva64.com/en/b/0226/

8ff6e53833 Correct Variant::hash_compare()
There was a logic error in #7815 which made
Variant.hash_compare() == Variant.hash_compare() always true.
In an attempt to short-circuit the NaN check I made an (in hindsight) obvious
error: 10 == 12 || is_nan(10) == is_nan(12)

This will be true for all inputs, except for the NaN, not-NaN case. The macro
has been updated to now generate:

(10 == 12) || (is_nan(10) && is_nan(10))

so:

(10 == 12)   || (is_nan(10)  && is_nan(12))  = false
   False  or (False and False) is False
(10 == 10)   || (is_nan(10)  && is_nan(10))  = true
   True or (False and False) is True
(Nan == 10)  || (is_nan(NaN) && is_nan(10))  = false
   False or (True and False) is False
(Nan == Nan) || (is_nan(NaN) && is_nan(NaN)) = true
   False or (True and True) is True

Which is correct for all cases.

This bug was triggered because the hash function for floating point numbers
can very easily generate collisions for the tested Vector3(). I've also added
an extra hashing step to the float hash function to make this less likely to
occur.

This fixes #8081 and probably many more random weirdness.

You last write readable code?

A new fantastic code format

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

b696beea65 Correct hash behavior for floating point numbers
This fixes HashMap where a key or part of a key is a floating point
number. To fix this the following has been done:

* HashMap now takes an extra template argument Comparator. This class
gets used to compare keys. The default Comperator now works correctly
for common types and floating point numbets.

* Variant implements ::hash_compare() now. This function implements
nan-safe comparison for all types with components that contain floating
point numbers.

* Variant now has a VariantComparator which uses Variant::hash_compare()
safely compare floating point components of variant's types.

* The hash functions for floating point numbers will now normalize NaN
values so that all floating point numbers that are NaN hash to the same
value.

C++ module writers that want to use HashMap internally in their modules
can now also safeguard against this crash by defining their on
Comperator class that safely compares their types.

GDScript users, or writers of modules that don't use HashMap internally
in their modules don't need to do anything.

This fixes #7354 and fixes #6947.

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!

b324ff7ea5 A bit of everything:
-IMA-ADPCM support for samples, this means that sound effects can be compressed and use 4 timess less RAM.
-New 3D import workflow based on Wavefront OBJ. Import single objects as mesh resources instead of full scenes. Many people prefers to work this way. Just like the rest of the imported resources, these are updated in realtime if modified externally.
-Mesh resources now support naming surfaces. This helps reimporting to identify which user-created materials must be kept.
-Several fixes and improvements to SurfaceTool.
-Anti Aliasing added to WorldEnvironment effects (using FXAA)
-2D Physics bodies (RigidBody, KinematicBody, etc), Raycasts, Tilemap, etc support collision layers. This makes easy to group which objects collide against which.
-2D Trigger shapes can now also trigger collision reporting in other 2D bodies (it used to be in Area2D before)
-Viewport render target textures can now be filtered.
-Few fixes in GDscript make it easier to work with static functions and class members.
-Several and many bugfixes.
