Tom Tromey 60b3cef2e4 Use function_view in cli-script.c
This changes some functions in cli-script.c to use function_view
rather than a function pointer and closure argument.  This simplifies
the code a bit and is useful in a subsequent patch.

ChangeLog
2018-05-04  Tom Tromey  <tom@tromey.com>

	* tracepoint.c (actions_command): Update.
	* mi/mi-cmd-break.c (mi_command_line_array)
	(mi_command_line_array_cnt, mi_command_line_array_ptr)
	(mi_read_next_line): Remove.
	(mi_cmd_break_commands): Update.
	* cli/cli-script.h (read_command_lines, read_command_lines_1): Use
	function_view.
	* cli/cli-script.c (get_command_line): Update.
	(process_next_line): Use function_view.  Constify.
	(recurse_read_control_structure, read_command_lines)
	(read_command_lines_1): Change argument types to function_view.
	(do_define_command, document_command): Update.
	* breakpoint.h (check_tracepoint_command): Don't declare.
	* breakpoint.c (check_tracepoint_command): Remove.
	(commands_command_1, create_tracepoint_from_upload): Update.
