Subject: [PATCH] client API: include the reason in MPV_EVENT_END_FILE

Otherwise, the client API user could not know why playback was stopped.

Regarding the fact that 0 is used both for normal EOF and EOF on error:
this is because mplayer traditionally did not distinguish these, and in
general it's hard to tell the real reason. (There are various weird
corner cases which make it hard.)
