Title: attr: Do not export variables externally

Fixes #824

Exporting variables in a dynamic library is a PITA. Let's keep
these values internally and wrap them through a helper method.

This doesn't break the external API. @arrbee, aren't you glad I turned
the `GIT_ATTR_` macros into function macros? :sparkles:
