Thu Aug 17 14:00:00 CEST 2017
This commit removes old stuffs of aplay and introduce sub-command style.
Old combinations of parameters are still available. In below list,
correspondence of old/new style are shown.
$ aplay list pcm (= -L, --list-pcms)
$ aplay list device (= -l, --list-devices)
$ aplay version (= --version)
$ aplay help (= -h, --help)
$ aplay transfer .. (the others)
