py3: make keys of keyword arguments strings

keys of keyword arguments on Python 3 has to be string. We are dealing with
bytes in our codebase so the keys are also bytes. We need to convert the keys
to unicodes to make the code run. We have to also reverse this process so that
functions on args dictionary like get() etc. don't result in key not found.

Also after this patch, `hg version` now runs on Python 3.5. Hurray!
