	Eliminate struct ui_stream.

	* ui-out.h (struct ui_stream): Delete.
	(ui_out_field_stream): Adjust prototype.
	(ui_out_stream_new, ui_out_stream_delete)
	(make_cleanup_ui_out_stream_delete): Delete declarations.
	* ui-out.c (ui_out_field_stream): Change prototype to take a
	ui_file instead of a ui_stream.  Adjust.
	(ui_out_stream_new, ui_out_stream_delete, do_stream_delete)
	(make_cleanup_ui_out_stream_delete): Delete.
	* breakpoint.c (print_breakpoint_location)
	(print_one_detail_ranged_breakpoint, print_it_watchpoint): Use
	ui_file/mem_fileopen instead of ui_stream/ui_out_stream_new.
	* disasm.c (dump_insns): Ditto.
	(do_mixed_source_and_assembly, do_assembly_only): Adjust
	prototype.
	(gdb_disassembly): Use ui_file/mem_fileopen instead of
	ui_stream/ui_out_stream_new.
	* infcmd.c (print_return_value): Ditto.
	* osdata.c (info_osdata_command): Don't allocate a local
	ui_stream.
	* stack.c (print_frame_arg, print_frame_args, print_frame): Use
	ui_file/mem_fileopen instead of ui_stream/ui_out_stream_new.
	* tracepoint.c (print_one_static_tracepoint_marker): Don't
	allocate a local ui_stream.
	* mi/mi-cmd-stack.c (list_arg_or_local): Use ui_file/mem_fileopen
	instead of ui_stream/ui_out_stream_new.
	(list_args_or_locals): Don't allocate a local ui_stream.
	* mi/mi-main.c (get_register, mi_cmd_data_evaluate_expression)
	(mi_cmd_data_read_memory): Use ui_file/mem_fileopen instead of
	ui_stream/ui_out_stream_new.
	* cli/cli-setshow.c (do_setshow_command): Ditto.
