Fix for PR gdb/209, PR gdb/156:

	* gdbarch.c, gdbarch.h: Rebuilt.
	* gdbarch.sh: Added `construct_inferior_arguments'.
	* cli/cli-decode.h (cmd_list_element): Added pre_show_hook.
	Typo fix.
	* cli/cli-setshow.c (do_setshow_command): Call the pre_show_hook.
	* infcmd.c (_initialize_infcmd): Set sfunc on `set args' command.
	(inferior_argc, inferior_argv): New globals.
	(notice_args_set): New function.
	(set_inferior_args): Clear inferior_argc and inferior_argv.
	(set_inferior_args_vector): New function.
	(get_inferior_args): Handle inferior argument vector.
	(run_command): Use get_inferior_args().
	(notice_args_read): New function.
	(_initialize_infcmd): Don't call set_inferior_args.
	* command.h: Typo fix.
	(cmd_list_element): Added pre_show_hook.
	* main.c (captured_main): Added --args option.
	(print_gdb_help): Document --args.
	* inferior.h (construct_inferior_arguments): Declare.
	(set_inferior_args_vector): Likewise.
