Implement generic debugging support. Implement a stabs reader and
a generic printer. * budbg.h, debug.c, debug.h, prdbg.c, rddbg.c, stabs.c: New files. * objdump.c: Include "debug.h" and "budbg.h". (dump_debugging): New global variable. (usage): Mention --debugging. (long_options): Add "debugging". (display_bfd): Handle --debugging. * Makefile.in (OBJDUMP_OBJS): New variable. ($(OBJDUMP_PROG)): Use $(OBJDUMP_OBJS). * binutils.texi, objdump.1: Document --debugging.
