Mark Thompson 4b2e3de8c0 cbs_h264: Fix default value for max mv lengths 
A recent version of the standard changed the max and default to 15, from
16 in older versions.  This updates the default to 15 to match, but the
max stays as 16 so that we don't reject older streams.

Haihao Xiang 65be65da37 cbs_h264: Need [] in the name when subscript is required 
Otherwise it will hit an assert in the function
ff_cbs_trace_syntax_element() in cbs.c, line 400.

Mark Thompson 0e782661d6 cbs_h264: Fix overflow in shifts 
The type of the result of a shift operation is unaffected by the type of
the right operand, so some existing code overflows with undefined behaviour
when the element length is 32.  Add a helper macro to calculate the maximum
value correctly and then use it everywhere this pattern appears.

  cbs_h264: Add hack for pic_timing with no active SPS

Partially fixes #6896 - the sample stream from that ticket now works, but
more obscure cases can still fail.

Mark Thompson 7157d95926 cbs_h264: Move slice_group_id array out of PPS structure 
It's very large, and is only used in some FMO streams.

Mark Thompson 13ca5d34ba cbs_h264: Add hack for pic_timing with no active SPS 
If there is exactly one possible SPS but it is not yet active then just
assume that it should be the active one.
