bf2299279f libs: decoder: h265: parser state after update dependent slice
If the dependent_slice_segment_flag is true, most slice info derived from last slice.
So we need check the slice type after we call populate_dependent_slice_hdr

c4d8b5c44c libs: decoder: h265: set parser info state at decoding codec data
Commit 1168d6d5 showed up a regression: decode_sps() stores the unit's
parser info in sps array. If that parser info comes from decoding
codec data, that parser info will have an undefined state which might
break ensure_sps().

This patch sets the parser info state, at decoding codec data, with
the internal parser state. This is similar with h264 decoder apprach.

f67ec886a3 libs: decoder: h264, h266: fix g_return_val_if_fail() missuse
g_return_val_fail() documentations says:

  If expr evaluates to FALSE, the current function should be
  considered to have undefined behaviour (a programmer error).
  The only correct solution to such an error is to change the
  module that is calling the current function, so that it avoids
  this incorrect call.

So it was missused in a couple parts of the H264 and H265 internal
decoders. This patch changes that to plain conditionals.

Also, it was included a couple code-style fixes.

06aa82f989 vaapidecode: Skip unparsable units from adapter
If the unit could not be parsed, just skip this nal and keep parsing
what is left in the adapter. We need to flush the broken unit in the
decoder specific parser because the generic code does not know about
units boundary. This increases error resilliance.

Before this, the broken unit would stay in the adapter and EOS would be
returned. Which stopped the streaming. Just removing the EOS would have
lead to the adapter size growing indefinitely.

Fixes regression introduced by commit 2eb2b26a.

Coverity scan bug:

Dereference after null check: Either the check against null is
unnecessary, or there may be a null pointer dereference.

While looking for hte lowest poc, according to rest of the code, the
picture in the dbp (decoded picture buffer) might be NULL, thus we
could check for a NULL picture before assigned as found.

Also, split a comma operator because it is considered as a bad
practice because it possible side effects.

ffd5028a38 decoder: hevc: Fill dependent slice segment headers while parsing
Copy the data into the dependent slice segment header from the
corresponding independent slice segment header during parsing.

Previously the reference to the "previous" independent header was
held through the parsing phase and then dereferenced during the
decoding phase. This caused all dependent headers to be populated
with the data of the AU's last independent header instead of the
proper corresponding header.

61045041c4 Add 10 HEVC 10 bit decoding support
Only supporting vaapidecode ! vaapisink combination for now.

Missing dependencies:
1: No support for P010 video format in GStreamer
2: No support for P010 vaGetImage()/vaPutimage() in vaapi-intel-driver
3: As a result of 1&2 , we have no support for Vaapi Video memory mapping
   through GstVideoMeta.

Right now we only set chroma format (YUV420 with more than 8 bits per channel)
for surface pool and keeping GST_VIDEO_FORMAT as ENCODED. The underlying format
of the surfaces is implementation (driver) defined, which is P010.
