e35085e5b5 qtdemux: Add more fields to SVQ3 caps
qtdemux only added the whole stsd atom as 'codec_data'
in its output caps for SVQ3. This patch makes it add
the SEQH (inside a SMI atom) and a gamma field (taken
from the gama atom) if available.

Fixes #587922

c917d65e6d qtdemux: unpack more information into image/x-j2c caps
* gst/qtdemux/qtdemux_fourcc.h: Add new fourccs for use by the mj2
  unpacker.
* gst/qtdemux/qtdemux.c (qtdemux_parse_trak): Unpack JPEG2000 component
  mapping and channel definitions from the jp2h header. Will add
  component-map and channel-definitions elements to the caps if the
  component maps or channel definitions are nonstandard, where standard
  order means RGB, 444 packed YUV, or greyscale, with no alpha channel.

Fixes #598915.

uninitialized.

Cast variables passed to printf to avoid warnings about incorrect

4590daf202 qtdemux: remove internal genre table
No need to maintain our own genre table in qtdemux. The genres are
identical to the ID3 genres, so we can just use libgsttag's
gst_tag_id3_genre_get() to look them up.

03f46a42e5 qtdemux: add durations modulo 1<<32
For calculating the durations of each sample, we are supposed to add each
duration modulo 1<<32 so make the elapsed time counter a uint32.

f65e6ea3a1 qtdemux: bail out instead of trying to alloc silly index sizes
If it looks like we would be allocating a silly size for our sample
index, just bail out instead of trying to allocate it. Helps with
broken or fuzzed files where we might end up trying to malloc a
couple of hundred MBs otherwise.

c8c9b0f35d qtdemux: move stco, stts, stss and stps atom parsing over to GstByteReader
Make sure we don't read beyond the atom boundary. Note that the code
behaves slightly differently in the corner case where there is not
enough atom data for the specified number of samples (n_samples_time)
in the atom, but still enough data to fill the pre-allocated index of
n_samples entries: before we would just stop parsing the stts data
and continue, whereas now we will likely error out. This should not
be a problem in practice though. We could maintain the old behaviour
by doing reads with a size check inside the loop if needed.

4be46b1586 qtdemux: use bytereader to parse stsz and stsc atoms
Use GstByteReader to parse stsz and stsc chunks, and check size of
available data before parsing it, instead of blindly assuming there
will be enough data. Fixes crashes with some fuzzed/broken files.
