Merge topic branch t/play into master

This small series contains a few minor tweaks for para_play. The most
obvious change is that para_play is no longer built on systems which
lack libreadline.

The merge conflicted badly in configure.ac due to the changes
introduced by the earlier merge of the "built" topic branch. The
resolution needs to modify the non-conflicting Makefile.real to exclude
para_play from the list of executables if libreadline is not present
while the corresponding commit of the "play" topic branch implemented
the logic in configure.ac.

Cooking for a month.

* refs/heads/t/play:
  play: Shut down alsa on input EOF.
  play: Simplify and improve get_key_map_seq().
  play: Remove pointless goto in play_post_monitor().
  Return from filter_setup() so callers can reset the terminal.
  Let para_play depend on libreadline.
