java/d: remove useless macros

Browse Source 
There are many macros that are defined and used just
once (b4_public_if, b4_abstract_if, etc.).  That's overkill.  Rather,
let's define a macro to build the "public class YYParser" line.

It appears that the same syntax with "extends", "abstract", etc. is
implemented in the D parser, which looks very fishy...

* data/skeletons/d.m4, data/skeletons/java.m4 (b4_public_if)
(b4_abstract_if, b4_final_if, b4_strictfp_if): Replace with
(b4_parser_class_declaration): this.
* data/skeletons/lalr1.d, data/skeletons/lalr1.java: Adjust.
