I agree, some time ago there was some discussion on using this vs some
exception mechanisms [1]. I still think this is the best choice, but ideas
on how to simplify this are welcome!

Look good and usable. Makes the code much cleaner.
A drawback I see for now is that the macro executes the expression for each
use. Using the nested if's the code would fall through to the end.
I am not sure what the consequence of this is, but probably not that large.

celix_errno.h would be the right place to add this. Feel free to create an
issue for this (optionally with patch). Of no one objects I can add it
without an impact on the existing code base.
