Cleanup unused err bindings. (#4246)

This removes:

- ERR_get_state which really shouldn't be public API.

- A bunch of functions that are really mostly useful within the library
  to add new errors. NB: I say mostly because they are also useful when
  trying to register a new error library, as osrandom does, but osrandom
  is written in C. Python code is more likely to be consuming errors.

- All function codes but EVP_F_EVP_ENCRYPTFINAL_EX because tests still
  reference it. Per PR #3609, function codes are kind of unstable. This
  finishes that up and cleans up the bindings.

- The "line" versions of querying the error queue, just because no one
  seems to be using them and there's a lot.

- Error-printing functions, which make less sense in Python since you'd
  probably wrap in an exception.

Error codes probably could also do with cleaning, but I've left them
alone for now.
