Fixed issue #1564: The set implementation should special-case PyUnicode instead of PyString
I moved the unicode_eq to stringlib/eq.h to keep the function static and possible inline for setobject.c and dictobject.h. I also removed the unused _PyString_Eq method. If it's required in the future it can be added to eq.h
