+ Introduce make_symbol.
+ make_symbol provides a means to construct a full symbol (kind,
+ value, location) in a single shot. It is meant to be a Symbol
+ constructor, parameterized by the symbol kind so that overloading
+ would prevent incorrect kind/value pairs. Unfortunately
+ parameterized constructors do not work well in C++ (unless the
+ parameter also appears as an argument, which is not acceptable),
+ hence the use of a function instead of a constructor.
+
+ * data/lalr1.cc (b4_symbol_constructor_declaration_)
+ (b4_symbol_constructor_declarations)
+ (b4_symbol_constructor_specialization_)
+ (b4_symbol_constructor_specializations)
+ (b4_symbol_constructor_definition_)
+ (b4_symbol_constructor_definitions): New.
+ Use them where appropriate to generate declaration, declaration of
+ the specializations, and implementations of the templated
+ overloaded function "make_symbol".
+ (variant::variant): Always define a default ctor.
+ Also provide a copy ctor.
+ (symbol_base_type, symbol_type): New ctor overloads for value-less
+ symbols.
+ (symbol_type): Now public, so that functions such as yylex can use
+ it.

+
+ Test 214 was failing: it greps with a pattern containing [ ]*
+ which obviously meant to catch spaces and tabs, but contained only
+ spaces. Tabulations in sources are a nuisance, so to simplify the
+ matter, get rid of all the tabulations in the Java sources. The
+ other skeletons will be treated equally later.

+ * data/java.m4, data/lalr1.java: Untabify.
