basefilectx: add an empty class that will be used as a parent of file contexts
Similar to the refactoring of context, we split common logic from filectx to a
parent class called basefilectx that will be inherited by filectx,
workingfilectx, and memfilectx. This will allow a clear disinction of all the
file contexts:
- filectx: read-only access to a filerevision that is already present in the repo,
- workingfilectx: a filecontext that represents files from the working directory,
- memfilectx: a filecontext that represents files in-memory
