py3: utility functions to convert keys of kwargs to bytes/unicodes

Keys of keyword arguments need to be str(unicodes) on Python 3. We have a lot
of function where we pass keyword arguments. Having utility functions to help
converting keys to unicodes before passing and convert back them to bytes once
passed into the function will be helpful. We now have functions named
pycompat.strkwargs(dic) and pycompat.byteskwargs(dic) to help us.
