So far, an indirection via String was necessary, causing at least 2 allocations and copies (String; String inside StringName).
Since StringNames often refer to string literals, this allows them to be directly constructed from C strings.
There are two formats: Latin-1 and UTF-8.
The Latin-1 constructor also provides the `p_is_static` flag: when the source has static storage duration, no copy/allocation will be needed.
However, the extension developer needs to uphold this lifetime guarantee.
Previously the `p_reversed` parameter didn't influence the order
in a correct way.
Also script overridden _notification functions were not called in
the correct order.
To fix this some `notification` functions had to add a `p_reversed`
parameter.
This made it necessary to adjust cpp-bindings.

This commit introduce separate types (e.g. GDNativeStringPtr vs GDNativeUninitializedStringPtr)
depending on if the pointed data is already initialized (C++ style where constructor is alway
called when create a variable even if it is to be passed as return value) or not (C style).
On top of that, small changes has been made to `GDNativeInterface` so that it methods are
consistent on using uninitialized return value.
This adds a way to ensure that methods that were modified in the Godot API will continue working in older builds of GDExtension even if the new signature is different.
```C++
// New version (changed)
ClassDB::bind_method(D_METHOD("add_sphere","radius","position"),&MyShapes::add_sphere);
// Compatibility version (still available to extensions).
ClassDB::bind_compatibility_method(D_METHOD("add_sphere","radius"),&MyShapes::_compat_add_sphere);
```
**Q**: If I add an extra argument and provide a default value (hence can still be called the same), do I still have to provide the compatibility version?
**A**: Yes, you must still provide a compatibility method. Most language bindings use the raw method pointer to do the call and process the default parameters in the binding language, hence if the actual method signature changes it will no longer work.
**Q**: If I removed a method, can I still bind a compatibility version even though the main method no longer exists?
**A**: Yes, for methods that were removed or renamed, compatibility versions can still be provided.
**Q**: Would it be possible to automate checking that methods were removed by mistake?
**A**: Yes, as part of a future PR, the idea is to add a a command line option to Godot that can be run like : `$ godot --test-api-compatibility older_api_dump.json`, which will also be integrated to the CI runs.
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
A while ago, argument arrays were passed as const GDNativeTypePtr* (void* const*)
This was changed to GDNativeConstTypePtr* (void const**), adding const on the value but removing it on the pointer level.
This commit changes argument types to const GDExtensionConstTypePtr* (void const* const*).
Besides object pointers, the same change is applied to variant pointers.
Non-exhaustive list of case-sensitive renames:
GDExtension -> GDNative
GDNATIVE -> GDEXTENSION
gdextension -> gdnative
ExtensionExtension ->Extension (for where there was GDNativeExtension)
EXTENSION_EXTENSION ->EXTENSION (for where there was GDNATIVE_EXTENSION)
gdnlib -> gdextension
gdn_interface -> gde_interface
gdni -> gde_interface
