Various Java skeleton improvements.

Browse Source 
* NEWS: Document them.

General Java skeleton improvements.
* configure.ac (gt_JAVACOMP): Request target of 1.4, which allows
using gcj < 4.3 in the testsuite, according to comments in
gnulib/m4/javacomp.m4.
* data/java.m4 (stype, parser_class_name, lex_throws, throws,
location_type, position_type): Remove extraneous brackets from
b4_percent_define_default.
(b4_lex_param, b4_parse_param): Remove extraneous brackets from
m4_define and m4_define_default.
* data/lalr1.java (b4_pre_prologue): Change to b4_user_post_prologue,
which marks the end of user code with appropriate syncline, like all
the other skeletons.
(b4_user_post_prologue): Add.  Don't silently drop.
(yylex): Remove.
(parse): Inline yylex.
* doc/bison.texinfo (bisonVersion, bisonSkeleton): Document.
(%{...%}): Fix typo of %code imports.
* tests/java.at (AT_JAVA_COMPILE): Add "java" keyword.
Support annotations on parser class with %define annotations.
* data/lalr1.java (annotations): Add to parser class modifier.
* doc/bison.texinfo (Java Parser Interface): Document
%define annotations.
(Java Declarations Summary): Document %define annotations.
* tests/java.at (Java parser class modifiers): Test annotations.
Do not generate code for %error-verbose unless requested.
* data/lalr1.java (errorVerbose): Rename to yyErrorVerbose.
Make private.  Make conditional on %error-verbose.
(getErrorVerbose, setErrorVerbose): New.
(yytnamerr_): Make conditional on %error-verbose.
(yysyntax_error): Make some code conditional on %error-verbose.
* doc/bison.texinfo (Java Bison Interface): Remove the parts
about %error-verbose having no effect.
(getErrorVerbose, setErrorVerbose): Document.
Move constants for token names to Lexer interface.
* data/lalr1.java (Lexer): Move EOF, b4_token_enums(b4_tokens) here.
* data/java.m4 (b4_token_enum): Indent for move to Lexer interface.
(parse): Qualify EOF to Lexer.EOF.
* doc/bison.texinfo (Java Parser Interface): Move documentation of
EOF and token names to Java Lexer Interface.
* tests/java.at (_AT_DATA_JAVA_CALC_Y): Remove Calc qualifier.
Make yyerror public.
* data/lalr1.java (Lexer.yyerror): Use longer parameter name.
(yyerror): Change to public.  Add Javadoc comments.  Use longer
parameter names.  Make the body rather than the declarator
conditional on %locations.
* doc/bison.texinfo (yyerror): Document.  Don't mark as protected.
Allow user to add code to the constructor with %code init.
* data/java.m4 (b4_init_throws): New, for %define init_throws.
* data/lalr1.java (YYParser.YYParser): Add b4_init_throws.
Add %code init to the front of the constructor body.
* doc/bison.texinfo (YYParser.YYParser): Document %code init
and %define init_throws.
(Java Declarations Summary): Document %code init and
%define init_throws.
* tests/java.at (Java %parse-param and %lex-param): Adjust grep.
(Java constructor init and init_throws): Add tests.
