[RFA] Kill cmd_async_ok.

[Vladimir Prus <vladimir at codesourcery dot com>]

Now that the 'ok for async mode' flag for commands is not used, this
patch garbage-collects whatever remains. OK?

- Volodya

	* cli/cli-decode.h (CMD_ASYNC_OK, set_cmd_async_ok)
	(get_cmd_async_ok): Remove.
	* cli/cli-decode.c (set_cmd_async_ok, get_cmd_async_ok): Remove.
	* cli/cli-cmds.c (init_cli_cmds): Don't use set_cmd_async_ok.
	* infcmd.c (_initialize_infcmd): Likewise.
	* thread.c (_initialize_thread): Likewise.
