* core.c (core_file_command): Print frame at coredump with
its level number, by calling print_stack_frame. * frame.h: Add selected_frame_level, print_stack_frame. * frame.h, stack.c: Remove print_sel_frame, print_selected_frame. * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c: Change print_sel_frame and print_selected_frame callers to print_stack_frame. * dbxread.c (read_ofile_symtab): Avoid empty else clause. * symfile.c (free_named_symtabs): Ditto. * main.c (main): wrap_here needs an arg. * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero. (solib_add): Avoid noise. (solib_create_inferior_hook): Lint. (sharedlibrary_command): Move dont_repeat to here. * utils.c (error): Call wrap_here to force buffered output. Small patches from Peter Schauer: * coffread.c (start_symtab): Free any existing line_vector before malloc-ing new one. (read_coff_symtab): Ditto for type_vector. * source.c (lines_to_list): New variable, replacing function. (all uses): Use as variable. (_initialize_source): Add 'set listsize' and 'show listsize'. * utils.c (lines_to_list): Remove function. * stack.c (print_frame_info): Use as variable. * defs.h (lines_to_list): Remove declaration.
