Don't reset the segment because we need the values for accumulation. the segment
is reset at start and after a flushing seek. Fixes some problems with files with
quicktime segments.

If it ever turns out that we really must use thoe specific
fourccs and not the generic one, we can still add a flavor
field to the caps later.

MPEG DASH has defined a set of new boxes to specify duration, indexes and
offsets of ISOBMFF fragments.

The Track Fragment Base Media Decode Time (tfdt) Box can in particular be
included inside a traf box to specify the absolute decode time, measured on the
media timeline, of the first sample in decode order in the track fragment.

This information can be used by the isomp4 demux to find out the current position of
an MP4 fragment in the timeline.

This patch adds code to isomp4 to:
- parse the tfdt box
- adjust the time/position member of the new segment sent when playback starts

... rather than a buffer, and the detailed info in the sample info
rather than caps.

... which is really useful for proper push mode seeking.

Fixes https://bugzilla.gnome.org/show_bug.cgi?id=680278

When it receives a seek in push mode, the qtdemux should first try to push the event upstream, and only if upstream fails fall back to
its own seek logic.

When receiving a duration query for TIME format, try to query upstream, and only if upstream fails fall back to qtdemux duration handling.

This fixes a not-negotiated error at least on mov files with
twos audio with two channels and video dvcp. As playbin and gst-launch
sample coming from the qtdemux.c file uses audioconvert and the latter
require format interleaved.

And use unchecked variant of GstByteReader where applicable

We do an ALLOCATION query to find out an allocator and parameters on the
srcpads. This way decoders (and sinks) can specify the memory and parameters
they want us to write into.

Set PTS and DTS on output buffers instead of just the PTS. In streaming cases
you want to synchronized encoded data based on the DTS because that is
monotonically increasing.

This reverts commit 53261261.

The GstDateTime->GDateTime change in core was apparently accidental,
and is now reverted.
