We are now using a pts based approach, libavutil/libavcodec should provide the
correct pts-es anyway. This also fixes an issue when seeking to a frame with a
pts set to zero.

We use a refresh loop which displays the frames and also does the polling for
pending events in a non-blocking way. If we know the required delay until the
next frame, then exactly that amount of sleeping will be done. After each
handled event we check if we have to display a frame which kind of makes
displaying the frame a high priority event.
This improves greatly the smoothness of the video output especially with 50fps
content.

After this change the dimensions of single image videos will be remembered when
coming back from full screen. The issue was mentioned in ticket #2174.

We simply remove the fixed length VideoState->audio_buf2 and use
the previously unused VideoState->audio_buf1.
Fixes ticket #2191.

Actually we just re-create the filters, since there is no way to flush them.
Fixes hangup with yadif filter on seeking forward caused by a filtered frame
with a pts before the seek.

Previously VideoPicture->skip was used for that, using videoq.serial enables us
to detect obsolete frames right after pushing flush_pkt to the packet queue, so
we don't have to wait for the decoder thread to pop the flush packet anymore.
This is good because until now a full video picture queue may have blocked the
decoder thread.

"que" sounds like a slang word to me. This commit renames a few
variables, fix the comments and the logging messages (sometimes along
with small other typo fixes).
If the XV image linesize was different from the width, SDL would create an
overlay wider than the actually requested one. This causes a greenish line on
the right, because the rightmost texel is blended with unset data. This patch
introduces a function which duplicates the rightmost texel to the unset space,
that way the blending will be done with duplicated border texels.

Set codec id in case another codec is forced on the context (e.g. when
the user specify the codec with -codec).
For example fix:
ffplay -vcodec pgmyuv -i "tests/vsynth1/%02d.pgm"
Fail with a meaningfull error message in case of bogus input.
Also the new options are more consistent with the rest of the tool
options, since it does not support generic stream specifiers.
Now it should work for the timestamp based and the byte based case as well.
Also only update the external clock if the seeking was successful.

In timestamp based seeking we update the external clock to the seek target,
therefore we should use sane timestamps even if libavformat could handle
seeking before the start of the file.

Otherwise playing the video could be much slower than realtime if the system
can't decode or display the frames fast enough.

The real av_sync_type may be different to VideoState->av_sync_type, because the
required audio or video stream for audio or video clock may not be available.
We will use a function to query the real av_sync_type which is used for
determining the master clock.

The purpose of the serial field is to accompany the decoded data during the
decoding process to know if the decoded data belongs to the data stream after
the latest packet queue flush.
