89fc5b4bd8 oggdemux: fix wedge when seeking twice quickly in push mode
This could happen when testing with navseek, and pressing
right and left at roughly the same time. The current chain
is temporarily moved away, and this caused the flush events
not to be sent to the source pads, which would cause the
data queues downstream to reject incoming data after the
seek, and shut down, wedging the pipeline.

Now, I can't really decide whether this is a nasty steaming
hack or a good fix, but it certainly does fix the issue, and
does not seem to break anything else so far.

0173afa38c oggdemux: implement push mode seeking
This patch implements seeking in push mode (eg, over the net)
in Ogg, using the double bisection method.
As a side effect, it also fixes duration determination of network
streams, by seeking to the end to check the actual duration.

Known issues:
- Getting an EOS while seeking stops the streaming task, I can't
  find a way to prevent this (eg, by issuing a seek in the event
  handler).
- Seeking twice in a VERY short succession with playbin2 fails
  for streams with subtitles, we end up pushing in a dataqueue
  which is flushing. Rare in normal use AFAICT.
- Seeking is slow on slow links - byte ranges guesses could be
  made better, decreasing the number of required requests
- If no granule position is found in the last 64 KB of a stream,
  duration will be left unknown (should be pretty rare)

6704b37fc3 oggdemux: do not propagate discontinuities in sparse streams
The first packet of a sparse stream may arrive after an initial
delay in the stream. If ogg_stream_packetout reports a discontinuity
in a sparse stream, do not propagate it to other streams in the
chain unnecessarily.

After all, we do hope to find actual data for these streams.
However, warn if we could not set up a chain when we find a

564eedd214 oggdemux: rename local variable for clarity
While the casual reader might end up bewildered by just why this
change might increase clarity, it just happens than, in the libogg
and associated sources, op is the canonical name for an ogg_packet
whlie og is the canonical name for an ogg_page, and reading this
code confuses me.

b7bb1e5633 ogg: do not use 32 bit modifiers to print serial numbers
If ints are 64 bits, 32 bits should get promoted in varargs anyway,
and we don't care about 16 bit ints.
This makes the code a lot more readable, and still gets us nice
hexadecimal 32 bit serialnos.

ea0d666d11 oggmux: refactor how EOS is determined
This decreases the number of buffers held on each pad by one,
eliminating next_buffer.  Simplifies the logic by relying solely
on CollectPads to let us know when a pad is in EOS.  As a side
benefit, the collect pads related code is structured more like
other CollectPad users.

The previous code would occasionally mark the wrong pad as EOS,
causing the code to get in a state where all the streams were
finished, but EOS hadn't been sent to the source pad.

55e767b632 oggmux: prefer headers from caps to determine stream type
Ogg mandates the first header packet must determine a stream's type.
However, some streams (such as VP8) do not include such a header
when muxed in other containers, and thus do not include this header
as a buffer, but only in caps. We thus use headers from caps when
available to determine a new stream's type.

d1c74779f9 oggmux: Use running time instead of timestamps
Theora and vorbis use running time (which is correct) for calculating
the granulepos for their ogg packets. Oggmux, however, used
timestamps to order the received buffers.

This patch makes it use the running time to compare buffer times
and also to timestamp pushed buffers.

Some bits of the code still use timestamps, but they are only
used to calculate durations, so it should be fine.
