Let's not leak details from src/shared and src/libsystemd into src/basic, even though you can't actually do anything useful with just forward declarations from src/shared. The sd-forward.h header is put in src/libsystemd/sd-common as we don't have a directory for shared internal headers for libsystemd yet. Let's also rename forward.h to basic-forward.h to keep things self-explanatory.
