h264parser: Remove un-needed checks and inline some functions
...
val and nr always exist (&nr, &value)
bits is always called smaller than the width
Makes parsing 30% faster

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.

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.

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.

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)
