Takashi Sakamoto Aug. 17, 2017, noon UTC
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)
