Akos Kiss 27682017e9 Remove unused internal functions 
The internals have surprisingly large number of unused functions at
surprising places. This patch cleans them out to make maintenance
easier and to prevent dead code having effect on future decisions.

The patch intentionally does not try to clean up public API but
focuses on internal modules only that are/should not be reachable
from "outside".

However, unit tests do access private API, thus tests of literal
storage had to be adjusted.
