EXTRA_LOOP_ARGS optional macro specifying extra arguments passed

+ This macro stores the seen but unconverted input bytes

+ FROM_ONEBYTE optional. If defined, should be the name of a

+ FROM_ONEBYTE (struct __gconv_step *, unsigned char);
+ and does a special conversion:
+ - The input is a single byte.
+ - The output is a single uint32_t.

Modules can use mbstate_t to store conversion state as follows:
