Once we drop iOS 7, we can also remove the legacy implementation based on UIAlertView

only handling them should differ. adds debugging

And add implicit discontinuity on format change.
Use only tracker events to change state (will need to move currentchunk away)

As mentioned by documentation
"It may be freed and replaced with a new buffer by libavformat."
" AVIOContext.buffer holds the buffer currently in use"

The video output is messed up if we only do a stream_Seek(). If we want
to seeking forward, we should decode and discard pictures to keep the
decoder at the right state. For seeking backward, seeking to the
beginning and decode from there. Since the bitrate is very low and the
decoding process is really simple, there is no obvious delay. I have
tested this strategy on a dual core ARM board.

This commit fixes the following assert in the DecoderThread function:
"assert( vlc_fifo_IsEmpty( p_owner->p_fifo) );"

Indeed, if input_DecoderFlush is called again (just after), p_owner->flushed
will be true and the input won't wait for the DecoderThread. As a consequence,
the input will send blocks while the DecoderThread is flushing, hence the
assert.
