tracing macros in Winelib applications.
The wine/lib, wine/ole, wine/unicode directories are gone. Simplify
the wine_unicode and wine_uuid detection.
Fix generation of the clean target (in some corner cases it could
generate a $(RM) command with no parameter).
Move the distclean target to the top-level Makefile and make it more
thorough.
Update a few autoconf constructs.
Remote commented out code in wrapper.c. If we need that code we can
always get it from CVS.
