VarArg methods have the return type Object in the API json for GDNative. This
can cause undefined behavior in some language bindings due to lack of
documentation on VarArg methods' behavior.
This changes the MethodInfo of:
- CSharpScript::_new
- GDScript::_new
- PluginScript::_new
It's not necessary, but the vast majority of calls of error macros
do have an ending semicolon, so it's best to be consistent.
Most WARN_DEPRECATED calls did *not* have a semicolon, but there's
no reason for them to be treated differently.
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.
