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.

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.

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.
