e6d83d8f96 jpegdec: Support libjpeg-turbo colorspace conversion 
The libjpeg-turbo has a built-in support for performing colorspace
conversion. The performance of this conversion is much better than
doing the same separately using videoconvert. Implement support for
this conversion to RGBx/xRGB/BGRx/xBGR formats. Other formats can
be easily added later.

- The decoding of various pixel formats can be tested and compared to
  non-libjpeg-turbo decoding as follows:
  for gfmt in {RGB,BGR}{,x} x{RGB,BGR} ; do
      echo "$gfmt"
      gst-launch-1.0 -q \
          videotestsrc pattern=colors ! \
          video/x-raw,format=${gfmt} ! \
          fakesink dump=true | \
	  head -n 200 | tail -n 1
      gst-launch-1.0 -q --gst-plugin-path=build/ext/jpeg/ \
          videotestsrc pattern=colors ! \
          video/x-raw,format=${gfmt} ! \
	  jpegenc ! \
	  jpegdec ! \
	  video/x-raw,format=${gfmt} ! \
	  fakesink dump=true | \
	  head -n 200 | tail -n 1
      done
  Result looks as follows, i.e. comparable:

  Notice how the alpha channel is set to arbitrary value in case of the
  libjpeg-turbo decoding into RGBx/BGRx/xRGB/xBGR pixel formats. This is
  documented in libjpeg-turbo README.md as follows:
    "
    When using the RGBX, BGRX, XBGR, and XRGB colorspaces during decompression, the
    X byte is undefined, and in order to ensure the best performance, libjpeg-turbo
    can set that byte to whatever value it wishes.
    "

- The interlaced num_fields=2 mjpeg stream can be generated and
  tested as follows (this does require mjpegtools):
  $ gst-launch-1.0 videotestsrc num-buffers=10 ! jpegenc ! multifilesink location=in%04d.jpg
  $ jpeg2yuv -f 25 -I t -L 0 -j in%04d.jpg | yuv2lav -f avi -o result.avi
  ...
  $ gst-launch-1.0 --gst-plugin-path=build/ext/jpeg/ filesrc location=result.avi ! \
       avidemux ! jpegdec ! video/x-raw,format=RGBx ! videoconvert ! autovideosink

4316be6571 splitmuxsink: Keep track of the pending input GOPs in a queue 
This cleans up input GOP handling and makes it possible to handle more
than 2 pending GOPs, which could happen before if keyframes are arriving
with too short of a distance between them.

ae8ceb801c splitmuxsink: Handle frame reordering due to B frames better 
Instead of assuming that the PTS of a keyframe is the lowest PTS of a
GOP, wait until the DTS has passed this PTS and take the minimum PTS up
to that point. That way the minimum PTS of a GOP can be determined, at
least for closed GOP streams. Open GOP streams still can't be handled
properly.

By knowing the minimum PTS of each GOP, keyframes can be requested at
the correct time relative to the GOP (and thus fragment) start and
fragment overflow calculations can calculate the correct durations of
the GOPs.

ed6823ad67 splitmuxsink: Use GST_CLOCK_STIME_NONE instead of 0 to initialize max out running time 
Otherwise streams with only DTS would misbehave while it is negative.

For outputting everything immediately at EOS, use G_MAXINT64 instead
which is bigger-or-equal to any other running time.

5ec82c1c4e rtphdrext: Pass just the attributes to the subclass 
Since the base class now does the parsing, there is no need
to reproduce that code in all the subclasses, just pass the attributes
which are the only relevant bit anyway.

Also, only store the direction if the subclass accepted the caps
