d2948bb259 qtdemux: fragmented support; fix offset handling and relax error raising
In particular, accept unknown stream in track fragment, and only error out
if that raises problems later on with respect to offset tracking.

Fixes #620283.

d4ceb8c7a6 qtdemux: remove dead code trying to update stream duration
On the one hand, it insufficiently checks whether it only updates a dummy
segment.  On the other hand, only doing this at the time the last sampled is
prepared (and sent downstream) is too little too late.

d66a3db6b8 qtdemux: fragmented support; proper and incremental moof parsing
That is, parse each moof in one pass (considering all contained streams'
metadata), and do so incrementally as needed for playback rather than
an initial complete scan of all moof (though all moov sample metadata
is fully parsed at startup).

6f05c5c050 qtdemux: parse fmp4 samples information
The fragmented mp4 format stores the tracks and samples information in the
'moof' boxes, which are appended before each fragment (fragment->'moof'+'mdat').
The 'mfra' box stores the offset of each 'moof' box and their presentation
time. The location of this box can be retrieved from the 'mfro' box, which is
located at the end of the file.
The 'mfra' box is parsed to get the offset of each 'moof' box and their
presentation time.
Each 'moof' box can contain information for one or more tracks inside
'tfhd' boxes. For each track in a 'moof', we have a 'trun' box, which
contains information of each sample (offset and duration) used to build
the samples table.

Based on patch by Marc-André Lureau <mlureau@flumotion.com>

994313da50 qtdemux: make qtdemux_dump_mvhd parse version 1 correctly
Versions 0 and 1 of mvhd have different sizes of its values
(32bits/64bits). This patch makes it dump them correctly.

Also use the right node in the parameter and not the root node.

4a244e0d55 qtdemux: AAC codec_data can be > 2 bytes long
This fixes the assumption that DecoderSpecificInfo must be 2 bytes long
for AAC files. The specification allows HE-AAC to be explicitly
signalled in a backward compatible way. This is done by means of an
additional information after the regular AAC header. It is expected that
decoders that can play AAC but not HE-AAC will parse the header normally
and ignore extended bits, much as they do for the HE-AAC specific payload
in the actual stream.
