Summary:
This includes initial support for the (hopefully final) updated Objective-C ABI, developed here:
https://github.com/davidchisnall/clang-gnustep-abi-2
It also includes some cleanups and refactoring from older GNU ABIs.
The current version is ELF only, other formats to follow.

Summary:
Protocols that were being referenced but could not be fully realized were being emitted without `properties`/`optional_properties`. Since all v3 protocols must be 9 processor words wide, the lack of these fields is catastrophic for the runtime.
As an example, the runtime cannot know [here](https://github.com/gnustep/libobjc2/blob/master/protocol.c#L73) that `properties` and `optional_properties` are invalid.
