Subject: Feedback cleanup

This patch splits pretty printing representation from IO operations.

- `Pp` is kept in charge of the abstract pretty printing representation.
- The `Feedback` module provides interface for doing printing IO.

The patch continues work initiated for 8.5 and has the following effects:

- The following functions in `Pp`: `pp`, `ppnl`, `pperr`, `pperrnl`,
  `pperr_flush`, `pp_flush`, `flush_all`, `msg`, `msgnl`, `msgerr`,
  `msgerrnl`, `message` are removed. `Feedback.msg_*` functions must be
  used instead.

- Feedback provides different backends to handle output, currently,
  `stdout`, `emacs` and CoqIDE backends are provided.

- Clients cannot specify flush policy anymore, thus `pp_flush` et al are
  gone.

- `Feedback.feedback` takes an `edit_or_state_id` instead of the old
  mix.

Lightly tested: Test-suite passes, Proof General and CoqIDE seem to work.
