Instead of directly rolling back the frame queue, keep the last displayed
picture in the queue and use a boolean variable to keep track if it is
displayed or not. This makes the code cleaner because it removes the
complicated logic in pictq_prev_picture.
There should be no change in functionality.

Whenever av_gettime() is used to measure relative period of time,
av_gettime_relative() is prefered as it guarantee monotonic time

Less than 0.04 sec delays should not be noticable, and it helps us with 50fps
content where some timing errors can cause a frame dup where it is not really
necessary.

After this commit applications needs to call av_format_inject_global_side_data()
or handle AVStream side data by some other means if they want it not to be lost.
This fixes a API incompatibility with libav.

When SDL could not allocate a YUV overlay or open a window, the video thread
got locked up because it waited for the allocation to finish forever.

It is no longer necessary. Also do frame timer and video current pos reset in
the main thread because with the wait removed, the timing would not be optimal
in the read thread.

Also make sure that we only exit or restart the video if it is not paused and
if the picture queue is empty.
There is still room for improvement (filters may also buffer some frames), but
the patch fixes the most common use cases and ticket #2783 as well.

Theoretically using start_time should also work if seeking is available and we
could determine that the next packet after a flush packet is the first packet
of a stream, but I could not think of an easy and clean way to do that, that is
why I sticked to the no seeking available condition for now.

Previously we estimated the audio packet pts instead of the frame pts,
therefore it only worked within a single packet (containing multiple frames).
The new method works accross seperate audio packets as well and also handles
better the case if a decoder buffers several packets before outputting a
decoded frame.

Also use negative stream_index for signaling obsolete audio packets. Using the
size alone is not enough, because size is 0 for null packets as well.

Add function avfilter_graph_parse_ptr() and favor it in place of
avfilter_graph_parse(), which will be restored with the old/Libav
signature at the next bump.
If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the
Libav-compatible signature for avfilter_graph_parse().
At the next major bump the current implementation of
avfilter_graph_parse() should be dropped in favor of the Libav/old
implementation.
Should address trac ticket #2672.

The corresponding codec options (skip_loop, skip_idct, skip_frame) can be
set in a more flexible way.
This technically causes a user interface break, but since the options
were not even documented and we just released a major version that should
not be a serious issue.
