As some libav encoders (such as MPEG2) use a thread_count parameter to control
how many threads to use, and since it was always being set to 0 (which uses
the default), suboptimal threading can sometimes be chosen. This extends the
libav encoders to allow for a max-threads parameter which is passed into
the internal structure to control this knob if applicable to the encoder.

gst_video_decoder_get_max_decding_time doesn't return a GstClockTime
but a GstClockTimeDiff, and thus one needs to compare it against
G_MAXINT_64.
The returning of a boolean and the extra subsequent code in _video_frame
was uselessly complicated.
The previous behaviour led to artefacts when the decoder tried to
hurry up.

As we don't know how many output buffers we need to operate, we need to
avoid pool that can't grow. Otherwise the pipeline may stall, waiting
for buffers. For now, we require it to be able to grow to at least
32 buffers, which I think is a fair amount of buffers for decoders.

Generate the section.txt file. Update the -docs.sgml file with the new sections.
If we want to actually see the baseclasses, we should define them with a _get_type() function
and have the wrapped types subclass them.
Fixes crash on EOS when no buffers have been received for some
reason, e.g. because the parser didn't output any.

* @param[in] frame AVFrame containing the raw audio data to be encoded.
* May be NULL when flushing an encoder that has the
* CODEC_CAP_DELAY capability set.
The AVFrame itself should be null, not the frame.data pointer

The output-corrupt property will set the CODEC_FLAG_OUTPUT_CORRUPT flag
in the codec context. The user can now decide whether libav outputs
corrupt frames or not.
Previous libav versions had this flag always set.

A AVCodecContext needs cleaning up before being freed.
Go through all of the allocations/setups to ensure none of them
can leak a context or its contents.
New libav will not call the release_buffer callback anymore when
avcodec_default_get_buffer() is called from get_buffer. Releasing of the
memory in a picture should now be done by registering a callback to the
avbuffer objects in the picture. There is some compatibility code to
wrap the memory we provide in get_buffer in avbuffer with a callback to
release_buffer but that is not done when avcodec_default_get_buffer()
is called.
Work around this by adding a dummy avbuffer object to the picture that
will release the frame.
