Per Bothner 7a9eb4c45a * defs.h (enum language): Add language_java. 
* java-exp.y, java-lang.c, java-lang.h, java-valprint.c:  New files.
	* Makefile.in:  Upadte for new files.
	* objfiles.c (allocate_objfile):  Allow NULL bfd argument.
	* symfile.c (deduce_language_from_filename):  Recognize .java.
