Merge branch 'pan/unicode_filename_warnings'

* pan/unicode_filename_warnings:
  Add file:list_dir_all/1 and file:read_link_all/1
  prim_file: Add list_dir_all() and read_link_all()
  Teach prim_file:set_cwd() to avoid entering non-translatable directories
  Make prim_file skip invalid filenames in unicode mode
  prim_file: Refactor functions that return filenames
  prim_file: Refactor handling of responses
  prim_file: Always open non-file ports in binary mode
  Test that list_dir("non-existing-dir") fails with the correct error
