Support reverse playback for ASF format.
Parse packets and queue the payloads, then push
the payload buffer to decoder in reverse order.
Video buffers are pushed from KeyFrame to next
Keyframe.

Add parsing of stereoscopic metadata, and place into the caps to
the decoder.
Fix parsing of Advanced Mutual Exclustion objects.

Based on a patch by HyeJin Choi <meeshel78@hotmail.com>
For bytestream we don't want to expose it as codec_data but rather as
streamheader as it is not out-of-band data but data that should be
prepended to the beginning of the stream before the other buffers.
https://bugzilla.gnome.org/show_bug.cgi?id=735070
Adds chained asfs handling to pull mode. It now checks if
there is a new asf header after the last packet (when it
is possible to know how many packets are) or it tries
checking if a processed packet that fails is an header
object.
Fixes#599718
Adds support for detecting and playing chained asfs
in push mode. asfdemux tries to detect a new asf start
by identifying the header object guid in a input buffer.
When it finds it, it resets its state, removing its pads
and creates new ones for the new file.
The simple index entries also contain the number of packets one needs
to retrieve at a given position to get a full keyframe. We therefore
use that information to retrieve all those packets in one buffer when
working in pull-mode.
When we receive a DISCONT as input, don't clear our complete state but simply
mark a discont that will be put on the next buffer. The code will be able to
handle and throw away incomplete data.
Add some more debug info.
Remove an unused variable.
This also makes timestamps (more) consistent before and after a possible
seek, and moreover makes for reasonable position reporting in live stream
(whose payload timestamps should not be taken for granted).
* Improve newsegment handling, e.g. upstream might live in TIME.
* Only send newsegment if we have needed info.
* Avoid reading past end of data section.

Activate streams (ie. add the pads to the element) depending on
whether we actually get data for those streams within the ASF
preroll value specified. Currently only done in pull-mode though
(this will fix problems with playbin hanging on mms streams once
we use this in push-mode as well).

New packet parsing code: should put halfway decent timestamps on
buffers, and might even set the appropriate keyframe/discont buffer
flags from time to time (and even if it doesn't, I'm at least able
to debug this code); only used in pull-mode so far. Still needs
some more work, like payload extensions parsing and proper flow
aggregation, and stream activation based on preroll. Stay tuned.

Some clean-ups and small fixes: rename asf_stream_context structure to
AsfStream; inline some three-line utility functions that are only used
once anyway and get rid of their associated helper structs; make debug
category global so that it is used by the debug statements in the other
file as well; simplify gst_asf_demux_get_stream(); fix accidental
implicit initialisation of stream->last_buffer_timestamp to 0, which
would lead to missing timestamps on the first buffer; put fourcc format
into video caps to make certain proprietary wmv decoders happy (for the
case of WMVA in particular); play_time is offset by preroll as well, so
fix overreporting of duration for some files.

Parse advanced mutual exclusion object and only add pads for
'hidden' streams (those in an extended stream header) that are
mutually exclusive with an already existing 'main stream' if
the broadcasting flag is not set. If the broadcasting flag is set,
assume that data for this stream isn't sent. (This should ideally be
solved better by making playbin more robust against this and/or by
making mmssrc send some information downstream about which streams
will be streamed). Fixes#353116.
