Description: More fixes for D language changes
  With this patch the code is accepted by gdc-8 8-20180414-1 without
  triggering deprecated feature warnings.
  - Convert I/O to use std.stdio module
  - Fix some unused broken code by deleting it
  - Avoid C-style array type notation
  - Use "goto case" to mark fall-through in switch statements
