Add support for Java demangling under the v3 ABI:

	Add support for Java demangling under the v3 ABI:
	* cp-demangle.c (NAMESPACE_SEPARATOR): New define.
	(struct demangling_def): Add `style' field.
	(demangling_new): New parameter `style'. Set it in demangling_t.
	(demangle_prefix): Use NAMESPACE_SEPARATOR.
	(demangle_type_ptr): Don't emit pointer symbol if doing Java output.
	(cp_demangle): New parameter `style'. Pass it to demangling_new().
	(main): Call cp_demangle with extra parameter.
	(java_demangle_v3): New function.
	(java_builtin_type_names): New. Table of primitive type names used
	for Java demangling.
	(demangle_builtin_type): Look up in java_builtin_type_names if doing
	Java output.
	* cplus-dem.c (cplus_demangle): Use java_demangle_v3 to do Java
	demangling.
	(long_options): Remove obsolete `java' option.
	(main): Remove explicit handling of `java' option. Instead, pass style
	parameter in cplus_demangle flags as gdb does.
	* testsuite/demangle.expected: Add some Java test cases.
