From bb324029ad442a1f6dd7049a6e6fc1cbe4a05799 Mon Sep 17 00:00:00 2001
From: Matthias Schiffer <mschiffer@universe-factory.net>

Subject: Allow using libsodium instead of NaCl

As libsodium has some strange include files (like a version.h), we try to use
absolute include paths whenever possible in fastd now and rename our generated
headers.
