Enums in C-binding are not extendable in a binary compatible and sane way

[elBoberido]

Required information

Operating system: all

Compiler version: all

Observed result or behaviour: The enums in the C-binding have an Name_SUCCESS value as last element in the enums. This results in constant ABI breakings when new enum values are added or the Name_SUCCESS value will end somewhere in the middle of the enum

Expected result or behaviour: Enum values can be appended without breaking ABI and without having the Name_SUCCESS somewhere in the middle of the enum

Conditions where it occurred / Performed steps: C-Binding

@elfenpiff what do you think, shall we move all the Name_SUCCESS at the top as first enum value. This has the additional benefit of corresponding to the integer value of 0 which is often used to indicate success
