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.
<!--
- para_play is no longer built if libreadline is not installed.
-->
* 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.
