This removes --enable-gpl and --enable-postproc from the
ffmpeg configure line, and disables building the postproc
gstreamer plugin.

avcodec_encode_audio is documented as taking the size of the output
buffer not the size of the input buffer. This fixes the use of the G722
encoder and makes the code more consistent with avconv from the libav
source tree.
Whether a frame is interlaced or not is unknown at the time of
buffer allocation, so caps on the buffer in opaque will have
a previous frame's interlaced flag set. So if interlacedness
changes, we update the buffer (if any) caps with the correct
interlaced flag once we know.

There seems to be a little bit of non obvious logic where
the QoS logic can decide to not drop decoding a frame and
pass it to ffmpeg, telling it to drop.
In this case, the QoS logic does not drop the frame itself,
but since the frame will end up being dropped, we still
mark it as dropped and post a QoS message.

This include decoder for ASS, SRT, PGS, DVD and DVB. Those are generated
with bad capabilities and are not usable in GStreamer. Other elements exist
to handle those subtitle formats.

Add a max-threads property, which defaults to '0 = auto'
Add a utility function taken from libschroedinger which sets
the ffmpeg worker thread count to match the computer processor
count by default.
When input buffer timestamps are invalid, next timestamp are used for
audio. Then, the next out timestamp is updated with the used timestamp
and the calculated duration. However, if the used timestamp is invalid,
it should not be used. Otherwise, the next buffer will use a wrong
timestamp that is not in the clipped segment, making the buffer to be
dropped.
This fixes playback with SBTVD MPEG TS streams, using AAC LATM.
A keyframe may be quite a while in the future, and the decoder
has no way of knowing this. A poor decision could mean quite some
time with no video output.
This decision should be left to the upstream element: a demuxer
might know about incoming keyframes, or some other element might
be able to request a keyframe.
Fixes bug #649372.
Previously autoconf appended too many additional quotes
to parameters like --with-ffmpeg-extra-configure=" --target-os=linux
--extra-cflags='-mfpu=neon -mfloat-abi=softfp'".
Fixes bug #648816.
