%% state record used by back-end at partial decode
%% active is set to 'yes' when a partial decode function is generated.
%% prefix is set to 'dec-inc-' or 'dec-partial-' is for
%% incomplete partial decode or partial decode respectively
%% inc_tag_pattern holds the tags of the significant types/components
%% for incomplete partial decode.
%% tag_pattern holds the tags for partial decode.
%% inc_type_pattern and type_pattern holds the names of the
%% significant types/components.
%% func_name holds the name of the function for the toptype.
%% namelist holds the list of names of types/components that still
%% haven't been generated.
%% tobe_refed_funcs is a list of tuples {function names
%% (Types),namelist of incomplete decode spec}, with function names
%% that are referenced within other generated partial incomplete
%% decode functions. They shall be generated as partial incomplete
%% decode functions.
%% gen_refed_funcs is as list of tuples with function names,type etc
%% that have been generated. It is to prevent duplicates of referenced
%% functions, and to generate the correct decode_inc_disp functions.
%% suffix_index is a number that is used as a suffix to make function
%% names unique. It is increased for each additional step into a
%% constructed type in an exclusive decode.
%% current_suffix_index is the index of the top type that is generated
%% at the moment. It may be the same as the current suffix_index or an
%% earlier value of it.
