Fixed: #902

is->max_frame_duration is way to short to disable AV correction

no-time-adjust can be used to prevent the player from returning an adjusted time, but rather, return the real time from the stream.

ffplay: use a separate struct for the rescaled YUVA AVSubtitle rectangles

Current code segfaults since the deprecation of AVSubtitleRect.pict because it
freed/realloced AVSubtitleRect.pict.data by itself.

The new code stores the generated YUVA AVSubtitle rectangles in their own
struct and keeps the original AVSubtitle structure untouched, because
overwriting it is considered invalid API usage.
