call it with a vb initialized to 0
- Returns:
- pointer after the parsed parts and sets vb->error
- Warning:
- don't forget to cleanup on error with free_via_list(vb)!

entry state must be F_PARAM, or saved_state=F_PARAM and state=F_{LF,CR,CRLF}! output state = L_PARAM or F_PARAM or END_OF_HEADER (and saved_state= last state); everything else => error
- Warning:
- param->start must be filled before, it's used in param->size computation.
