src: add compat header file definitions

This patch restores the original nft_* definitions from the header files to
avoid sudden compilation breakage of the existing clients of this library.

Then, moving forward the idea is to deprecate the old nft_* symbols anytime
soon using __attribute__((deprecated)) from the header files to warn our users
that they need to update their code.
