The minimum change is to disallow bytes/str mix:
 - os.listdir(unicode)->unicode and ignore invalid files
   (current behaviour is to return unicode and bytes)
 - os.readlink(unicode)->unicode or raise an error
   (current behaviour is to return unicode or bytes)
 - remove os.getcwdu() (use its code -which is better- for getcwd) 
   and fix the test_unicode_file.py

listdir() change (ignore invalid filenames) is important to avoid strange bugs 
in os.path.*(), glob.*() or on displaying a filename.

I can generate a specific patch for these issues. It's just a subset of my 
last patch.
