py3: stop normalizing 2nd argument of *attr() to unicode...

py3: stop normalizing 2nd argument of *attr() to unicode Now that we don't byteify strings, we can stop normalizing the 2nd string argument to getattr() and remove explicit overrides we were using in the code base. We no longer use some helper functions in the source transformer, so we remove those as well. Differential Revision: https://phab.mercurial-scm.org/D7012
