* mi/mi-cmds.c (mi_cmds): Route -exec-run, -exec-until,

	* mi/mi-cmds.c (mi_cmds): Route -exec-run, -exec-until,
	-target-download and -target-select via CLI, so that
	the quoting rules are the same as they were (unfortunately)
	in all prior gdb releases.
	* mi/mi-cmds.h (mi_cmd_exec_run, mi_cmd_exec_until)
	(mi_cmd_target_download, mi_cmd_target_select): Remove.
	* mi/mi-main.c (mi_cmd_exec_run, mi_cmd_exec_until)
	(mi_cmd_target_download, mi_cmd_target_select): Remove.
	(mi_cmd_execute): Set current_token even for commands
	routed via CLI.
