• avcodec/cbs : Avoid leaving the ... out in calls to variadic macros

  avcodec/cbs : Avoid leaving the ... out in calls to variadic macros
  According to C99, there has to be at least one argument for every ...
  
  in a variadic function-like macro. In practice most (all ?) compilers also
  
  allow to leave it completely out, but it is nevertheless required : In a
  
  variadic macro "there shall be more arguments in the invocation than there
  
  are parameters in the macro definition (excluding the ...)." (C99,
  
  6.10.3.4).
  CBS (not the framework itself, but the macros used in the
  
  cbs_*_syntax_template.c files) relies on the compiler allowing to leave
  
  a variadic macro argument out. This leads to warnings when compiling in
  
   pedantic mode, e.g. "warning : must specify at least one argument for
  
  '...' parameter of variadic macro [-Wgnu-zero-variadic-macro-arguments]"
  
  from Clang.
  Most of these warnings can be easily avoided : The syntax_templates
  
  mostly contain helper macros that expand to more complex variadic macros
  
  and these helper macros often omit an argument for the .... Modifying
  
  them to always expand to complex macros with an empty argument for the
  
  ... at the end fixes most of these warnings : The number of warnings went
  
  down from 400 to 0 for cbs_av1, from 1114 to 32 for cbs_h2645, from 38 to
  
  0 for cbs_jpeg, from 166 to 0 for cbs_mpeg2 and from 110 to 8 for cbs_vp9.
  These eight remaining warnings for cbs_vp9 have been fixed by switching
  
  to another macro in cbs_vp9_syntax_template : The fixed values for the
  
  sync bytes as well as the trailing bits for byte-alignment are now read
  
  via the fixed() macro (this also adds a check to ensure that trailing
  
  bits are indeed zero as they have to be).
