mpv/input/input.c
arpi ce587559f7 This patch adds the functionality to disable/enable subtitles while playing 
a video. I mapped it to the input-keyword "sub_visibility".
This keyword is  mapped to the 'v' key on the keyboard. I tested the patch
with old-fashioned  subtitles, with freetype subtitles and DVD subtitles.
Works fine. The patch also includes documentation updates.
