* java-*: Renamed to jv-*, to make fit within 14 characters.

	* jv-lang.h (java_type_print):  Added declaration.
	* jv-typeprint.c:  New file.  Provides java_print_type.
	* jv-lang.c (java_link_class_type):  New function.
	(java_language_defn):  Replace c_print_type by java_print_type.
	* Makefile.in:  Update accordingly.
