It would be useful to first concentrate on the first part, the refactoring
that introduces flags and RF_BINARY. This would provide a patch that is easier
to review and does not have the following problems:
  - internal_fread_file still exists, although fread_file is a no-op wrapper
    around it.
  - In tests/test-read-file.c, please terminate the main() function with a
    return statement. We assume C99 only in modules that explicitly list 'c99'
    as a dependency. If it's trivial to avoid this dependency, let's do it.
  - The NEWS file needs an entry.
