(Frodo) Many changes. Layout sections now work!

* Added list_empty, list_replace
* Added relocation to buffers, removed base address
* Added buffer_resolve, buffer_add_reference, buffer_add_target,
  psiconv_unique_id functions
* Modifified other buffer functions to work with references
* Added comments to buffer.h
* Added write_offset function
* Added reference support in functions where needed
* Corrected extra/rewrite error message
* Corrected numerous bugs to make layouts work.
