needed to split lib into separate headers and source files, which requires lots of drudgery to specify paths for each include filename (no longer relying on same-directory lookups)

also rename wchar -> utf8 to avoid conflict with <wchar.h> (requires
rebuild of workspace)
(unfortunately copying history fails to "502 bad gateway"; had to delete
old + add new independently)

This was SVN commit r7340.
