20669d461a Fix 'ignoring return value of function declared with const attribute' 
This always happens with GstByteReader/Writer and friends when
not taking into account returned boolean of the _read/_write functions
(which is actually wrong).

Make use of the *_unchecked variant as much as possible, or take the
returned value into account.

5c9f790075 codecparsers: h264: record number of emulation prevention bytes in slice_header(). 
Some hardware video decode acceleration API (VA-API, DXVA) require
a bit count to the first macroblock, minus the number of emulation
prevention bytes. So, instead of having the consumer of the library
scan the slice_header() again, just record that number while parsing.

4964db6a1c codecparsers: h264: fix parsing of VUI parameters. 
max_dec_frame_buffering was mis-parsed because log2_max_mv_length_vertical
was parsed twice.

c92efe38e9 codecparsers: h264: fix ref_pic_list_modification() 
The entries were not filled in linearly and the termination was not
recorded either. Now, the actual number of modifications is recorded
similarly to dec_ref_pic_marking(). i.e. an explicit counter instead
of storing the termination value in the array.

c4d987b6d3 codecparsers: Variant of _identify_nalu without checks 
This is useful for cases where the caller *knows* that the provided
input contains a whole NALU and can therefore avoid:
* the expensive checks for the next start code (which won't be present)
* delaying the input parsing (since we would need the next incoming NALU
  in order for the parsing code to detect the next start code)

12c678c7cf codecparsers: minor fixes 
Const-ify one more VLC table. Fix spelling of 'hybrid'.
No need to explicitly call ensure_debug_category() everywhere,
that will be done automatically from GST_LOG() and friends
via GST_CAT_DEFAULT.

cannot be accessed since they have not been set.

It was also possible that sps->fps_{num,den} end up initialized here.
