    parse.y: Remove almost all *_gen macros by passing parser_params explicitly
    
    In parse.y many functions were suffixed "_gen" and had companion macros
    to pass struct parser_params implicitly, which made parse.c bigger and
    more obscure.
    
    This change expands and removes almost all "*_gen" macros.  This
    requires explicit passing of struct parser_params, i.e., we need to
    write "foo(p, ..)" instead of "foo(..)".  However, it is just extra
    three letters.  I believe that this is easier to understand.
