There are a couple of functions that create rna pointers. For example `RNA_main_pointer_create` and `RNA_pointer_create`. Currently, those take an output parameter `r_ptr` as last argument. This patch changes it so that the functions actually return a` PointerRNA` instead of using the output parameters. This has a few benefits: * Output parameters should only be used when there is an actual benefit. Otherwise, one should default to returning the value. * It's simpler to use the API in the large majority of cases (note that this patch reduces the number of lines of code). * It allows the `PointerRNA` to be const on the call-site, if that is desired. No performance regression has been measured in production files. If one of these functions happened to be called in a hot loop where there is a regression, the solution should be to use an inline function there which allows the compiler to optimize it even better.
