6523c5bcb6 h264decoder: Add ability to lookup by system_frame_number
This is to avoid having to create a reference chain in decoders from
GstVideoCodecFrame to GstH264PIcture to implementation wrapper.

So this change introduces:

 - gst_h264_dpb_remove_outputed (dpb)
 - gst_h264_dpb_get_picture(dpb, system_frame_num)
 - gst_h264_decoder_get_picture (dec, system_frame_num)

In order to ensure that frames can be looked up during the draining
process, we now first remove all (including reference) frames that
have been outputed but are still in the DPB. Then for each remaining
buffers, we remove it from the DPB to reach reference 1 and output it.

Previously we could take all not outputed outside of the DPB which would
prevent lookup by the base class.

82fb55bdff codecs: h264decoder: Make GstVideoCodecFrame hold the last reference of the buffer
... when gst_video_decoder_finish_frame() is called.

Some subclasses attach GstBuffer to GstH264Picture as an user data
which will increase reference count of the buffer. It would result
to buffer copy per every frame.

Background here is, GstVideoDecoder wants writable output buffer for
GstMeta handling, and if the output buffer is not writable
(i.e., reference count is not one), the buffer will be copied.
Even if underlying GstMemory wouldn't be copied, buffer copy operation
will introduce extra memory allocation overhead which is not optimal.

By this modification, subclass might be able to receive the last
reference to GstH264Picture

e921a07715 codecs: h264decoder: Pass GstVideoCodecFrame to output_picture()
All subclasses are retrieving list to get target output frame, which
can be done by baseclass. And pass the ownership of the GstH264Picture
to subclass so that subclass can clear implementation dependent resources
before finishing the frame.

The lifecycle of GstH264Picture is being managed by our DPB
implementation. If it's still required, subclass can do that
by itself in the new_picture() method.

9ff332e15d codecs: h264decoder: update max_dpb_frames only if VUI is present
There are some streams, with HRD, where the the calculated
max_dpb_frames is zero (max_dpb_mbs is less than size mb). In order to
get the dbp size it is required to rely on the VUI parameters if they
are present.

According to the spec Annex E.2.1

**max_dec_frame_buffering** specifies the required size of the HRD
decoded picture buffer (DPB) in units of frame buffers.  It is a
requirement of bitstream conformance that the coded video sequence
shall not require a decoded picture buffer with size of more than
Max(1, max_dec_frame_buffering) frame buffers to enable the output of
decoded pictures at the output times specified by dpb_output_delay of
the picture timing SEI messages. The value of max_dec_frame_buffering
shall be greater than or equal to max_num_ref_frames. An upper bound
for the value of max_dec_frame_buffering is specified by the level
limits in clauses A.3.1, A.3.2, G.10.2.1, and H.10.2.

When the max_dec_frame_buffering syntax element is not present, the
value of max_dec_frame_buffering shall be inferred as follows:

– If profile_idc is equal to 44, 86, 100, 110, 122, or 244 and
constraint_set3_flag is equal to 1, the value of
max_dec_frame_buffering shall be inferred to be equal to 0.

– Otherwise (profile_idc is not equal to 44, 86, 100, 110, 122, or 244
or constraint_set3_flag is equal to 0), the value of
max_dec_frame_buffering shall be inferred to be equal to MaxDpbFrames.

c213b6ea17 nalutils: Improve slightly the error trace
Until now, bound check would simply trace the values and the range. This
enhances the trace by also tracing the name of the variable that was to be set
or read. This is not magically perfect in all cases, but greatly speed the
debugging work. Here's an example before and after this change:

Before: gst_h264_parser_parse_slice_hdr: value not in allowed range. value: 819183, range -87-77
After:  gst_h264_parser_parse_slice_hdr: value for 'slice->slice_qp_delta' not in allowed range. value: 819183, range -87-77

The unit tests only checked for vulkan_dep.found(), which can
be true if the libs are there but glslc was not found, in which
case the plugin wouldn't be built and the unit tests would fail
because of missing vulkan plugins.

Doesn't really make much sense to build the vulkan integration lib
either if we're not going to build the vulkan plugin, so just disable
both for now if glslc is not available.
