revamp console output options 

- the old meaning of -V[V] was moved to -D{n|N}, as these are really
  debugging options.
- don't print the info messages by default; this can be re-enabled with
  the -V switch, and is implied by most debug options (it was really
  kind of stupid that verbose/debug operation disabled these).
- the sync algo/state debugging can be separately enabled with -Ds now.
