0c2c909497 video: Always provide a buffer in gst_video_(enc|dec)oder_allocate_output_buffer()
We have no way of tell the caller of the exact error (e.g. if we're flushing),
so will have to wait until the caller uses API that returns a GstFlowReturn,
for example when pushing this buffer.

0be8d14965 videodecoder: Try harder to push writable buffers downstream
For this release the corresponding GstVideoCodecFrame before
pushing the buffer. The buffer will now be writable unless
the subclass still holds another reference to the buffer or
the frame.

c3651a7905 videodecoder: always send the new buffer to parse functions
When we get a new buffer, always call the parse function, even if it is a 0
sized buffer. For theora we need to also decode 0 sized buffers.
Ideally we would like to make theoradec be packetized but that fails currently
because of oggdemux and because of the assumptions that the base class makes.

31312d586e videodecoder: Don't blindly assign DTS to PTS
DTS and PTS usually have a non-zero offset between them in MPEG-TS,
so assigning DTS to PTS is almost always wrong.  The other, newer
timestamp recovery code does it correctly if we leave it as invalid.

ceb6585d26 videodecoder: warn if frame list gets long
Decoders that get unparsed input are internally leaking nearly
every incoming buffer.  This checks that case.

0bb5c6c012 videodecoder: Only keep track of timestamps if the subclass is parsing data
Otherwise we just pass through the timestamps directly and don't
need to waste additional memory for them.

706498cb6e videodecoder: finetune missing timestamp estimating
Monitor for reordered output timestamps, and then avoid oldest DTS
as PTS approach, and try for an oldest PTS as out PTS approach,
if at least all valid PTS available.

Avoids bogus estimating upon sparse available input PTS, and tries
to handle all-keyframe input, or input PTS which are actually DTS.

ef5316fbb0 videodecoder: Send serialised events immediately, after we're pre-rolled.
Only hold back events until the first buffer is generated, then just
send them directly. Otherwise, important events like 'still-frame' are
held forever, waiting for a frame that'll never arrive.

efe9e31b34 videodecoder: getters for pool and allocator
Sometimes the decoder would need to use the pool or the allocator for
something else than just allocating output buffers. For example, the querying
for different parameters, such as asking for a bigger number of buffers to
allocate in the pool.

This patch expose a two getters accessors: one for the buffer pool and the
other for the memory allocator.
