Simplify _compat.py now that we only run on newer Pythons

- We have u'literals' so we don't need a _u() function.
  For the record the Emacs replacement regex was
  `_u(\(['"]\)\([^)]*\)\1) -> u\1\2\1`. Amazingly, I typed that right
  on the first try.

A few things were only used in one (test) file or function, so it was
better to keep the use, if any, local and out of the "public" api:

- We can use io.StringIO everywhere and it's fast. It was only
 imported in one file anyway.
- We can just import pickle. It was only imported in one file anyway.
- TEXT was only used in one test function, `type(u'')` is just as
 clear (especially since the usual name is `text_type`).
- reload was only used in one test function, so move the definition
 there.
